Wise Guy tool terms
Words you will meet inside our betting tools, from the +EV Board to the Parlay Builder. Each one is explained here in full, with a link to the tool that uses it.
Prices and fair value
Implied win %
The win rate a price needs just to break even. It still has the book's margin inside it, so the two sides of a market add up to more than 100%.
Example: -110 implies 52.4%: win more often than that at -110 and you profit over time.
How our tools use it: 1 divided by the decimal price. For -110: 1 / 1.909 = 52.4%. Remove the margin with the No-Vig calculator to get a fair win %.
Edges and stakes
Data support
A 0 to 100 checklist of how well the data backs this price. It is not a win chance.
Example: Strong 70+, Moderate 45 to 69, Thin under 45.
How our tools use it: A 0 to 100 checklist score: how many books post both sides, whether the edge is a normal size, the edge band, and an exact sharp match. Strong is 70+, Moderate 45 to 69, Thin under 45. A price that is not confirmed is capped at Thin. It is not a win probability.
Trust tier
The server's label for how well-backed an edge was when first seen: Strong, Solid or Speculative.
Example: 6 books, a normal-size edge and a sharp match reads Strong.
How our tools use it: Points for books quoting (6+ books 45, 4 to 5 38, 3 30, 2 16), +18 when the edge is 10% or less, +17 for an edge of 1% to 8% (+8 under 1%, +4 above 8%), +20 when sharp-confirmed. Strong is 70 or more, Solid 45 or more, else Speculative. Strong was called Verified before Oct 20.
Actionable
A price fresh and clean enough for us to suggest a stake. Prices that fail stay on the board marked Verify price.
How our tools use it: The price has a fresh quote (under 25 minutes pregame, 3 minutes live), a quote time, passes the long-price and exchange checks, and its fee is known. Only actionable prices get a stake.
Verify price
We could not confirm this price right now. Open the book and check the number before you bet it.
How our tools use it: We could not confirm this price right now: the quote is stale, has no quote time, or changed since the edge was computed. No stake is suggested and Data support is capped at Thin. Open the book and check the number first.
Trust tier
The board's label for how well-backed the edge was when first seen: Strong, Solid or Speculative.
How our tools use it: The board's trust tier for the edge when it was first seen.
Qualified
Whether the edge was big enough for its price to count: longer prices need bigger edges.
Example: A +250 price needs a 4% edge to qualify.
How our tools use it: Qualified = the edge cleared the board's odds-scaled minimum (2% at short prices, 4% at +200, 6% at +300).
Payout and profit
Payout is everything the book pays back on a win, your stake included. Profit is the payout minus the stake.
Example: $100 at +150 pays $250: $150 profit plus the $100 stake.
How our tools use it: Payout = stake times the decimal price. Profit = payout minus stake.
Splits and sharp signals
Steam
Several books moved this line the same way within minutes before the flag.
How our tools use it: At the first flag: a coordinated move across books on this game and market in the 6 hours before, toward our side (With us) or the other side (Against us); None = no steam.
Sharp money (Circa vs DraftKings)
Sharp Vegas money on one side while public app bettors are on the other, when the edge was flagged.
How our tools use it: At the first flag: Circa money 55%+ on a side while DraftKings bets are 45% or less on it, a gap of 15+ points, same market and number. With us = that side is ours; Against us = the other side; None = checked, no such split. Recorded from Oct 21 while signals are on.
Market agrees
Whether sharper prices outside the US books agreed with our fair price.
How our tools use it: At the first flag: Pinnacle's no-vig price or the de-vigged Pinnacle fair within 2.5 points of our fair, and no reference (incl. Kalshi, Polymarket) more than 5 points away = Agrees; references present but not close = Differs.
Vegas agrees
Whether the Las Vegas books' price agreed with our fair price.
How our tools use it: At the first flag: the Vegas books (Circa, Westgate, South Point, Wynn, Station Casinos) median no-vig price on the same number within 2.5 points of our fair = Agrees; quoted but not close = Differs. Recorded while Vegas references are on.
Sharp Report rating
How strongly the Sharp Report pointed at our side, using only the rating recorded before the edge was flagged.
Example: 70 or more reads Sharp side; under 31 reads Sharp money on the other side.
How our tools use it: At the first flag: the Sharp Report rating of our side as first recorded before the flag. Sharp side = 70 or more, Leans sharp = 58 to 69, No clear sharp side = 43 to 57, Leans the other way = 31 to 42, Sharp money on the other side = under 31, Not rated = recorded with no proven reading on that side. No rating recorded by the flag reads Unknown.
Slow book
The market moved our way and this book had not caught up yet.
How our tools use it: At the first flag: the market steamed toward our side in the last 3 hours and the book with our price had not moved (Slow book); None = no such lag.
Exchanges and prediction markets
Exchange buyers
Exchange buyers on Kalshi and Polymarket: which side the buyers who paid the asking price took, by dollars. Not a betting split: every trade has a buyer and a seller.
Example: 65% of the dollars traded on the Eagles reads strongly with.
How our tools use it: Share of the dollars Kalshi and Polymarket buyers paid for the edge's side since the market opened, at the first flag: 65%+ strongly with, 58%+ with, 42% or less against, 35% or less strongly against. Thin = under 30 trades or $5,000 traded; None = no prediction market listed the game (or the line was more than a point away).
Exchange buyers
Exchange buyers is not a betting split: on an exchange every trade has a buyer and a seller, so the money is always even. This shows which side the buyers who paid the asking price took.
Example: Exchange buyers 62% on the Eagles: 62% of the money from buyers who paid the asking price went to the Eagles.
How our tools use it: Exchange buyers is not a betting split. On an exchange every trade has a buyer and a seller, so the money is always even. This shows which side the buyers who paid the asking price took. Kalshi and Polymarket publish each trade's taker side; ProphetX and Novig publish money matched or contracts traded only, so they show volume, never a side.
Big prediction market trades
Trades of $1,000 or more on Kalshi and Polymarket. When most big-trade dollars land on one side, larger bettors lean that way.
How our tools use it: Trades of $1,000 or more on Kalshi and Polymarket since the market opened: With = 65%+ of those dollars on the edge's side, Against = 65%+ on the other side, Mixed otherwise, None = fewer than 3 big trades.
Polymarket US
The US version of the Polymarket prediction market. We show its moneyline prices only to members in states where it is listed as available.
Example: Prices show in every state. If your state is not set, the bet button reads Set your state.
How our tools use it: Moneylines only (NFL, college football, NBA, college basketball, NHL, MLB, WNBA), pregame within 36 hours, snapshot fresh under 25 minutes. The price to buy is the ask (or 1 minus the bid on the other side), after its fee. Members only, in a state where it is listed as available; it never sets the fair price.
Exchange depth
How much money was available at the flagged price on the exchange.
How our tools use it: When an exchange held the flagged price and published its size: Thin = under $250 available at that price on a sports exchange (Novig, ProphetX) or under $500 on a prediction market (Kalshi, Polymarket); else OK. Books that publish no size read Unknown (limits are never estimated).
Exchange buyers
Which side the Kalshi and Polymarket dollars were on when the edge was flagged.
How our tools use it: Share of the dollars Kalshi and Polymarket buyers paid for the edge's side since the market opened, at the edge's first flag: 65% or more = strongly with, 58% or more = with, 42% or less = against, 35% or less = strongly against. Thin = under 30 trades or $5,000 traded; None = no prediction market listed the game (or the line was more than a point away).
Big prediction market trades
Which side the $1,000-plus trades on Kalshi and Polymarket were on.
How our tools use it: Trades of $1,000 or more on Kalshi and Polymarket since the market opened: With = 65% or more of those dollars on the edge's side, Against = 65% or more on the other side, Mixed otherwise, None = fewer than 3 big trades.
Prediction market depth
How many dollars you could take at the price on Kalshi, Polymarket, Novig or ProphetX at the flag.
How our tools use it: Only when the edge's best price was Kalshi, Polymarket, Novig or ProphetX on the same number: dollars a buyer could take at that price from the order book at the flag. Thin = under $500 on a prediction market (Kalshi, Polymarket) or under $250 on a sports exchange (Novig, ProphetX), the same rule as Exchange depth (the price may not fill). Not used = the best price was a sportsbook or the book was not recorded.
Exchange $ at the price
How many dollars were available at the price on an exchange or prediction market, in bands.
Example: Bands: under $500, $500 to $2,500, $2,500 to $10,000, $10,000 or more.
How our tools use it: Only when the edge's best price was Kalshi, Polymarket, Novig or ProphetX on the same number: the dollars a buyer could take at that price at the flag, in bands. Not used = the best price was a sportsbook.
Exchange buyers
Exchange buyers is not a betting split. Every exchange trade has a buyer and a seller, so this shows which side the buyers who paid the asking price took.
Example: Kalshi since open: Patriots 55%, Bears 45% of buyers' money, $504K traded.
How our tools use it: Share of the money paid by buyers on each side of the market at that exchange, since the market opened or in the last hour. Under 10 trades or $500 traded the row is hidden; under 30 trades or $5,000 it is shown with a Light trading tag and never counts as a signal (the shared light-trading rule).
Exchange price vs books
Members: the exchange's latest price for a side, as a win chance, next to the books' no-vig win chance for the same side. A gap means the two markets disagree.
Example: Kalshi 58% · books 54%: the exchange rates the side 4 points higher than the books.
How our tools use it: The exchange contract's latest price as a percent beside the books' no-vig fair percent for the same side. Shown to members only, and only when the exchange market is fresh (read in the last 45 minutes) and not light trading.
Results and proof
First flag per game
The board can flag the same game many times as prices move. We count only the first flag, a rule you could have followed at the time.
Example: Flagged at +3.1% at noon and +5% at 6 pm: only the noon flag counts.
How our tools use it: How the Results page counts bets when the board flags the same game more than once as prices move. Only the first flag on each game's moneyline, spread or total counts. That is a rule you could have followed at the time, and a later, bigger edge never replaces it.
Market filter
Game lines (the headline), player props, or every market. Props count the same way: pre-game prices only, the first flag per game, stat and player.
Example: Player props, first flag: one row per game, stat and player, however many times the price moved.
How our tools use it: The Results page opens on game lines (moneylines, spreads and totals). Player props lists the graded player-prop edges the board flagged before the game started, one first flag per game, stat and player. All markets adds alternate lines too. Props and All markets show counts and the list of graded picks, never totals.
The headline view
The one result the page leads with, picked by a published rule that is the same on every load, never by hand.
How our tools use it: The one result the +EV Board Results page leads with, picked by a published rule that is the same on every load. The rule scores every sport (and all sports together), every edge minimum (2%, 3%, 5% and 10%) and every window, always using pre-game bets, the first flag on each game's moneyline, spread or total, and 1 unit flat at the posted price after fees.
The view with the most units over at least 300 decided bets, with units and ROI above zero, leads; if none reaches 300, the biggest over 100 decided bets leads with a small-sample note; failing that, closing line value leads (over half of 300 or more closes beaten); failing that, no number leads. A losing view never leads.
Every view compared
Every combination of sport, minimum edge and window, winning and losing. Compare that many and one will look good by luck, so trust sample and range, not rank.
How our tools use it: A table in the Advanced part of the Results page listing every combination of sport, minimum edge (2%, 3%, 5% and 10%) and window, using pre-game bets and the first flag per game, scored in the stake mode you choose. Every view is listed, winning and losing. Compare that many views and one will look good by luck, so trust a view by its sample size and its range, not by its rank.
Windows
The time range the results cover. Shorter windows hold fewer bets, so they swing more.
Example: Since Aug 20 is the whole ledger; Since Sep 24 starts after the September 24 board update.
How our tools use it: The time ranges on the Results page. Since Aug 20 is the whole ledger. Last 30 days counts games in the last 30 Eastern game days, from edges first seen after the September 24 board update. Since Sep 24 counts edges first seen after that update. Shorter windows hold fewer bets, so their results swing more.
Minimum edge
Only edges at or above this size are counted.
Example: Set 3% and a 2.5% edge drops out of every figure.
How our tools use it: Only edges at or above this size count. It is applied first, before the first flag per game is chosen, exactly like the rest of the page.
Board view
The edges a member saw on the +EV board with its default filters.
Example: A prop priced +180 sits behind Show more, so it is not in the Board view.
How our tools use it: What a member saw with the board's default filters: every tab All, every sport, est. edge 1%+ after fees, higher-variance markets and edges starting within 15 minutes hidden, no state and not My books only. Yes = on the board by default, No = hidden by a default filter. Use Every price (not first flag per game) and Minimum edge 1% to match the board's list.
Break down by
Splits the bets into one row per value of what you pick, like one row per sport.
How our tools use it: Splits the filtered bets into one row per value of the dimension you pick. A row marked as counting twice (team, division) can hold one game under two teams, so those rows do not add up to the total.
Unknown
We had no data for that filter on those bets, so they are shown as Unknown instead of being guessed or dropped.
How our tools use it: The row has no data for that rule (for example, books quoting was recorded from Sep 30, splits were archived from Oct 1). Unknown rows are kept and shown, never dropped or guessed.
Proof labels
Our verdict on whether a tool signal or system holds up on graded results: Proven winner, Promising, needs more data, Not working, or Too few results.
Example: Proven winner = made money on older and newer results and on the most recent 20% we held back.
How our tools use it: Proven winner: every proof test passed and the pooled ROI is above 0. The tests, in order: 150+ graded results in both the older and the newer half; the newer half's 95% range is above 0; it survives a false-discovery check across every row or version tried (q 0.10 or lower); the held-back most recent 20% has 50+ results and an ROI above 0.
Promising, needs more data: ROI above 0, a test not passed yet. Not working: ROI at or below 0 with 30+ graded (shown in red only at 100+ graded with the whole 95% range below 0). Too few results: under 30 graded. Arbitrage gets no label (no win or loss to prove).
Holdout
The most recent 20% of results, kept aside and never used to pick the rule. A rule that also wins there is far less likely to be luck.
Example: 500 graded bets: the newest 100 are the holdout, tested only at the end.
How our tools use it: The most recent 20% of graded results by time (the cut is at 80% of the rows in time order). Rows before the cut are split by count into an older and a newer half. The explorer cuts per signal type, the monthly retune uses one cut for everything, and Labs cuts per source and family from the whole population, so no system picks its own holdout dates.
Is it proven?
We split your system's graded results by date and test both halves plus a held-back recent slice. Only a system that passes them all is a Proven winner.
Example: Making money but under 150 results in each half reads Promising, needs more data.
How our tools use it: We split every graded result by date. Proven winner = it made money on the newer half with room to spare, kept making money on the most recent 20% we held back, and still passes after counting every version you have tried. Promising = making money, not every test passed yet. Not working = at or below break-even. Too few results = under 30 graded.
Live or past-season replay
Live results are what our tools recorded at the time; past-season replay re-runs the board on stored odds. The two are never added together.
How our tools use it: Live results = edges and signals as our tools recorded them at the time, graded from final scores. Past-season replay = the +EV Board re-run on stored odds from past seasons; not live results and not a picks record. They cover some of the same games, so they are never added together.
Only what was known
Every filter is something you could have known before placing the bet, so a system can never peek at the result.
Example: The closing line is not a filter: you cannot know it when you bet.
How our tools use it: Every filter here was known before the bet could be placed. Readings from after the bet (the closing line, how long a price lasted, later flags) are never filters, so a system cannot peek at the result.
Versions tried
Every different set of filters you test counts once. Try enough versions and one will look good by luck, so the bar for Proven winner rises with each try.
How our tools use it: Every different set of filters you test counts once. Try enough versions and one will look good by luck alone, so the bar for Proven winner rises with every version (the false-discovery check multiplies by the versions tried). A warning shows from 5 versions.
Units
1 unit = your usual bet size. A win at +150 pays 1.5 units, a win at -110 pays 0.91, a loss costs 1 unit.
Example: At $100 a bet, +25 units is about +$2,500.
How our tools use it: 1 unit = your usual bet size. A win at +150 pays 1.5 units, a win at -110 pays 0.91, a loss costs 1 unit. At $100 a bet, +25 units is about +$2,500.
Return per $100
What came back for every $100 risked on bets that won or lost. Pushes return the stake and count nowhere.
How our tools use it: What came back for every $100 risked on bets that won or lost. Pushes return the stake and count nowhere.
Likely range
Where the true return probably sits, given how many bets there are. A wide range means luck can still explain the result.
How our tools use it: Where the true return probably sits, given how many bets there are. A wide range means luck can still explain the result.
Edge
How much better the price was than our estimated fair price when the board first saw it.
Example: A 3% edge is an estimated $3 per $100 over many bets, if the fair price is right.
How our tools use it: How much better the price was than our estimated fair price when the board first saw it. A 3% edge is an estimated $3 per $100 over many bets, if the fair price is right.
Labs
Build your own betting system from filters and test it on our graded results before you risk a dollar on it.
Example: +EV Board edges, NFL, edge 3% or more, home underdogs: see how that system did.
How our tools use it: A member saves a set of filters (a system) and tests it on graded results: +EV Board edges (live and past-season replay), Sharp money, reverse line movement, steam and middles (live), sharp opener and market line moves (replay). Results are graded results of the filters you chose, not Wise Guy Team plays. Past results do not predict future results.
Wise Guy Team record
Every Wise Guy Team play is posted before the game and graded after it, wins and losses, at $100 = 1 unit. Each program keeps its own record.
Example: A $100 play that wins at -110 adds +0.91 units; a loss costs 1 unit.
How our tools use it: Units at $100 = 1 unit from the graded units on each play. A graded play is a win or a loss; pushes and postponed plays are left out of the won-lost record. Programs are never blended, and Owner Selections always stand alone. The years claim is 6 straight winning years: full calendar years 2020 to 2025 on the officials board, and the current year is not counted until it closes. The model's +EV Board results are separate from Wise Guy Team plays.
CLV in probability points
How many win-chance points the closing price gave your side over the price you took. Positive means you beat the close.
Example: You took -105 (51.2%), it closed -120 (54.5%): +3.33 points.
How our tools use it: Closing implied % minus your implied %, both straight from the prices (margin included), the same unit the Bet Tracker uses.
CLV as a relative %
The same CLV as a share of your own implied chance, so small and long prices compare fairly.
Example: +3.33 points on a 51.2% ticket is +6.5% relative.
How our tools use it: (Closing implied % minus your implied %) divided by your implied %. Positive means you beat the close.
Units and ROI in these tables
Units is how many equal-size bets you would be up or down. ROI is units won divided by units risked, so it compares a big group with a small one.
Example: +9.4u at +34.9% ROI over 27 bets: up nine and a half bets, about $35 back for every $100 risked.
How our tools use it: A win at +150 pays +1.5 units, a win at -110 pays +0.91, a loss costs 1 unit, after exchange fees. ROI = units won divided by units risked on won and lost bets. Small groups swing a lot, so read the Bets column first.
Arbitrage, middles and parlays
Best bets only
A stricter rule for auto-build: only legs with strong data, a qualified edge and a price of +250 or shorter. Off by default.
How our tools use it: An optional stricter bar for auto-build: actionable quote, Data support 70+ or an exact sharp match, qualified after fees (2% under +200, 4% to +299, 6% beyond), +250 or shorter. Off by default; the default rule is any leg at +0.5% or better after fees at the chosen book, the same rule the live builder uses.
Hedge stake
The bet on the other side that sets your result in advance, whichever way the game goes. You give up some upside to remove the risk.
Example: A $10 ticket paying $500 can be hedged so both outcomes return the same amount.
How our tools use it: Equal result: the stake that makes the payout on both outcomes the same, net of what you already staked. Break even: the smallest stake that returns your total outlay if the hedge wins.
Round robin
Every parlay of a chosen size built from your picks, each with the same stake. One loss does not sink the whole ticket.
Example: 4 picks by 2s = 6 two-leg parlays.
How our tools use it: Number of parlays = combinations of the picks taken k at a time. Payout if all win = the stake times the sum of every k-pick product of the decimal prices.
Arbitrage margin
How much the prices on every side cross after fees. Above zero, a stake split exists that returns more than the total staked whatever the result.
Example: +105 and +102 on the two sides of one game: about 1.7% back on the total.
How our tools use it: 1 minus the sum of the implied chances of every outcome after each book's fee. Stakes are split so every outcome returns the same amount, then rounded to whole dollars and every outcome is checked again.
Game context
Rest days
How many full days off the team had since its last game. Tired teams often play worse.
Example: Played Sunday and again Tuesday = 1 rest day.
How our tools use it: Sides and moneylines: full days off for the team we picked since its previous game (0 = back-to-back; a normal football week is 6; off a bye is 12 or more). From the schedule, which is known in advance. Not applicable = the rule does not cover this sport or market.
Rest edge
How much more (or less) rest our team had than the opponent.
Example: Our team had 3 days off, the opponent 1: 2 extra days.
How our tools use it: Our team's rest days minus the opponent's: 3 or more extra days, 1 to 2 extra, even, 1 to 2 fewer, 3 or more fewer. Not applicable = the rule does not cover this sport or market.
Back-to-back spot
Whether a basketball or hockey team is playing on back-to-back nights or a packed stretch.
How our tools use it: Basketball and hockey. Sides and moneylines, our team: Back-to-back (played yesterday), 3rd game in 4 days, Normal (1 day off), Rested (2+ days off). Totals: Either team on a back-to-back, or Neither. Not applicable = the rule does not cover this sport or market.
Travel distance
How far the team traveled since its last game. Long trips can mean tired legs.
Example: Boston to Los Angeles is about 2,600 miles.
How our tools use it: Miles from the team's previous game venue to this one (our team on sides and moneylines; the visiting team on totals): under 50, 50 to 499, 500 to 999, 1,000 to 1,999, 2,000 or more. Not applicable = the rule does not cover this sport or market.
Time zones crossed
How many time zones the team moved since its last game, and which way.
How our tools use it: Time zones moved since the previous game (our team; the visiting team on totals): None, 1 east, 2+ east, 1 west, 2+ west. Not applicable = the rule does not cover this sport or market.
Body clock
Whether the start time feels early or late to the team's body after flying across time zones.
Example: A West Coast team playing at 1 pm in New York reads Early.
How our tools use it: Our team (visiting team on totals): Early = playing 2+ zones east of home with a local start before 2 pm; Late = 2+ zones west of home starting 7 pm local or later; Normal otherwise. Not applicable = the rule does not cover this sport or market.
Home stand or road trip
Which game of a home stand or road trip this is for the team.
How our tools use it: Daily sports. Which game of a home stand or road trip this is (our team; the visiting team on totals): 1st, 2nd or 3rd, 4th or later. Not applicable = the rule does not cover this sport or market.
Elo vs market
Elo is a simple team rating that rises with wins and falls with losses. This compares what our Elo ratings expect with the board's price.
Example: Elo says 60%, the board's fair price says 54%: Elo strongly backs us.
How our tools use it: Our own Elo ratings (both teams with 5+ rated games) against the board: moneylines (not soccer, where a draw is possible) compare Elo's win chance for our side with the board's fair chance (5+ points higher = Elo strongly backs us, 2 to 5 = backs us, within 2 = about the same, then the other way); spreads compare Elo's expected margin with our points (3+ points of cushion = strongly backs us, 1 to 3 = backs us). Not applicable = the rule does not cover this sport or market.
Covers, last 5 (ATS form)
How often the team beat the spread in its last 5 games. ATS means against the spread.
Example: Covered 4 of the last 5 = 4 or 5.
How our tools use it: Our team's covers in its last 5 games with a closing spread, counting only games final before the first flag: 4 or 5, 3, 2, 0 or 1. Fewer than 5 such games = Thin sample. Not applicable = the rule does not cover this sport or market.
Covers, last 10 (ATS form)
How often the team beat the spread in its last 10 games.
How our tools use it: Our team's covers in its last 10 games with a closing spread, final before the first flag: 7 or more, 5 to 6, 3 to 4, 0 to 2. Fewer than 10 = Thin sample. Not applicable = the rule does not cover this sport or market.
Over/under trend, last 5
Whether both teams' recent games have mostly gone over or under the total.
Example: 7 of the last 10 went over and we bet the over: With us.
How our tools use it: Totals: both teams' last 5 games with a closing total (10 games), final before the first flag. Over trend = 65%+ went over, Under trend = 35% or less; With us = the trend matches our side, Against us = the other side, Mixed otherwise. Either team under 5 games = Thin sample. Not applicable = the rule does not cover this sport or market.
Over/under trend, last 10
The same over/under trend over both teams' last 10 games.
How our tools use it: Totals: the same rule over both teams' last 10 lined games (20 games). Not applicable = the rule does not cover this sport or market.
Official total lean
Some referees and umpires see more overs or unders than usual. This checks the key official's history on totals.
Example: An umpire whose games went over 58% of the time = over lean.
How our tools use it: Totals only, recorded when the board first flagged the edge: in the key official's earlier games (MLB home plate umpire, NBA crew chief, NFL and NHL referee) the total went over the closing number at least 56% of the time (over lean) or at most 44% (under lean). With = our side matches the lean; Against = the other side; No lean = enough games, no lean; Thin sample = fewer games than the floor. Other markets read Not a total.
Wind
Forecast wind at game time. Strong wind can cut scoring in football and change fly balls in baseball.
How our tools use it: Forecast wind at the start, only from a forecast captured BEFORE the first flag: Calm = under 8 mph, 8 to 14, 15 to 19, 20 mph or more; Indoors = dome (or the MLB park report says the roof is closed). No forecast before the flag = Unknown. Not applicable = the rule does not cover this sport or market.
Temperature
Forecast temperature at game time.
How our tools use it: Forecast temperature at the start, captured before the first flag: 32F or colder, 33 to 49, 50 to 69, 70 to 84, 85F or hotter; Indoors = dome or roof closed. Not applicable = the rule does not cover this sport or market.
Rain chance
Forecast chance of rain or snow at game time.
How our tools use it: Forecast chance of precipitation at the start, captured before the first flag: Dry = under 20%, 20 to 49%, 50% or more; Indoors = dome. Not applicable = the rule does not cover this sport or market.
Roof
Whether the stadium is open air, has a fixed dome or a roof that can open.
How our tools use it: Outdoor sports: Dome = fixed roof; Retractable = retractable roof (open or closed not known in advance); Open air otherwise. Not applicable = the rule does not cover this sport or market.
Weather flag (totals)
A flag for weather that tends to matter on totals: strong wind, freezing cold or likely rain.
How our tools use it: Totals in outdoor NFL, college football and MLB games: wind 15 mph+, temperature 32F or lower, or 50%+ chance of rain in the forecast nearest kickoff (Flag); None = none of those. Domes read None.
Move since the open
Whether the line has moved toward or away from our side since it opened.
How our tools use it: Game lines: the consensus opening line (captured before the first flag) against the market at the flag. With the move = the market moved toward our side since the open (spreads and totals 0.5+ points; moneylines 2+ points of win chance on the median book); Against the move = it moved away from our side; No move otherwise. Not applicable = the rule does not cover this sport or market.
Market maturity
Early markets are thin and move a lot; mature markets have more books and more betting behind them.
How our tools use it: At the first flag: Early = 12+ hours before the start (36+ for NFL and college football) or fewer than 5 books quoting; else Mature.
Injury news after the line
Whether an injury report changed after the board first showed the edge.
How our tools use it: When the edge was first recorded: an injury-report change for either team after the board first showed it (After); None = no change.
Starter status (MLB, NHL)
Whether the starting pitchers or goalies were confirmed when the edge was flagged.
How our tools use it: MLB pitchers and NHL goalies at the first flag: both listed (Confirmed), a listed starter changed after the board first showed the edge (Changed), else None.
Board controls
Board tabs
Quick views of the board: Best bets (the best-backed prices), Sharp-matched, and Longshots (+300 and longer).
How our tools use it: Best bets: actionable, Data support 70+ or an exact sharp match, qualified after fees, +250 or shorter. Sharp-matched: our exact sharp check agrees. Longshots: +300 and longer, noisy, smaller stakes.
Recommended order
The default sort: prices you can act on first, then by edge, stake size and data support together.
How our tools use it: Actionable prices first, then by edge after fees, stake size and Data support together. Pick another sort to rank by one thing only.
Hide starting in 15 min
Hides games about to start or already in progress, because pregame prices close fast.
How our tools use it: Hides games that start within 15 minutes, and games already in progress, because pregame prices close fast.
Day filter
Show today's games, tomorrow's, or all of them, by Eastern time.
How our tools use it: Today and Tomorrow use Eastern time calendar days. Games in progress count as Today. Games that started on an earlier day and are not in progress (delayed, postponed or not yet removed by the books) show only under All.
