A two-outcome habit from other sports, such as comparing only the favorite and underdog, throws away the draw, which is about a quarter of matches. This skill reads the whole triple.\n\n## When to Use\n\n- \"What are the odds on Liverpool against City?\"\n- \"Which book has the best price on the draw?\"\n- \"How much margin is each book charging?\"\n- \"Did the line move toward the home side?\"\n- \"What was the closing line for this finished match?\"\n\n## When NOT to Use\n\n- Converting prices to fair probabilities: `odds-analysis`\n- Anytime goalscorer prices: `goalscorer-prop-modeling`\n\n## Commands Available\n\n| Command | What It Does | Credits |\n|---------|-------------|---------|\n| `get_schedule` | Upcoming fixtures with `line`: books count, median `home_ml`, `draw_ml`, `away_ml`, `total`, `home_handicap`, `implied` | 2 |\n| `get_odds` | Per-book three-way moneyline, handicap, total, with open and close, and for finished matches the outcome | 5 (`game_id`), 10 (`date`), 2 per match (`season`) |\n| `get_line_movement` | Time series of each book's `home_ml`, `draw_ml`, `away_ml`, `home_handicap`, `total` before kickoff | 10 |\n| `get_game` | Includes each book's opening and closing line inside a full match (5) | 5 |\n\n## Commands That Do NOT Exist\n\n| Not Available | Use Instead |\n|--------------|-------------|\n| `get_live_odds` | `get_odds` for a match, `get_schedule` for the median line. No in-play prices |\n| `get_best_odds` | Compare the `books` array from `get_odds` yourself |\n| `get_btts_odds`, `get_corners_odds`, `get_card_odds` | Not available. The markets are three-way moneyline, goal handicap and goal total |\n| `get_closing_line` | The `*_close` fields in `get_odds` |\n| `get_public_betting` | Not available. Infer from movement only, cautiously |\n\n## What the Prices Look Like\n\nMoneylines are American odds. A home price of `+290` risks 100 to win 290. A price of `-118` risks 118 to win 100. The three prices for one book sum to more than 100% implied, and the excess is the overround.\n\n`get_odds` returns, per match, a `books` array. Per book:\n\n| Field | Meaning |\n|-------|---------|\n| `provider`, `source` | Book name; `the_odds_api` or `espn` |\n| `home_ml_open`, `home_ml_close` (and `draw_`, `away_`) | Opening and closing moneyline. ESPN rows often have `null` opens |\n| `close_prob` | No-margin home, draw and away probabilities plus `overround` |\n| `home_handicap_*`, `total_*`, `over_odds`, `under_odds` | Goal handicap and total where posted. Many Odds API rows have `null` here |\n| `captured_at` | When the row was captured. For ESPN rows on old matches it can be well after the match, so it is not a kickoff timestamp |\n\nFor a finished match there is also `outcome`: `result` (`H`, `D`, `A`), `median_total`, `median_home_handicap`, `over`, `home_covered`.\n\n## How It Works\n\n**Step 1: Get the match id.** `get_schedule` for upcoming, `list_games` (see `match-lookup`) for past.\n\n**Step 2: Pull every book.**\n\n```\nget_odds {\"game_id\": \"740968\"}\n```\n\n**Step 3: Find the best price per outcome.** Independently for home, draw and away, take the highest American number (the largest payout). For `+330` versus `+290`, `+330` is better. For `-106` versus `-118`, `-106` is better. The best price for each side usually sits at a different book.\n\n**Step 4: Measure each book's margin.** Convert each price to implied probability, sum the three, subtract 1.\n\n```\nimplied(+x) = 100 / (x + 100)          implied(-x) = x / (x + 100)\noverround   = implied_home + implied_draw + implied_away - 1\n```\n\nBetting exchanges and Pinnacle typically run far below high-street books. `close_prob.overround` gives it directly.\n\n**Step 5: Clean the rows before ranking.** Drop or flag a book whose three prices sum to less than 100% (negative overround) or far above 115%. Exchange snapshots in thin markets produce nonsense. In one line-movement pull, an exchange row early in the series read `-323 / -1000 / -323`, which is not a real market.\n\n**Step 6: Movement.** `get_line_movement` returns snapshots per book. ESPN lines are captured once a day, The Odds API lines hourly for matches in the next two days, so a quiet series is not necessarily a quiet market.\n\n```\nget_line_movement {\"game_id\": \"401879267\"}\n```\n\nCompare the first and last real snapshot per book, in implied probability rather than raw price, because a move from `+230` to `+200` and from `-110` to `-125` are different sizes.\n\n## Worked Example\n\nCrystal Palace vs Arsenal, closing lines from `get_odds {\"game_id\": \"740968\"}` (Arsenal won 2-1, `result` A):\n\n```\nbook              home    draw    away    overround\n888sport          +290    +250    -118     8.3%\nBet 365 (espn)    +310    +260    -118     6.3%\nBetfair Exchange  +330    +290    -106     0.4%\nDraftKings        +300    +270    -110     4.4%\nFanDuel           +320    +260    -115     5.1%\nMarathonbet       +315    +274    -110     3.2%\nPinnacle          +317    +279    -111     3.0%\nWilliam Hill      +290    +250    -118     8.3%\n```\n\nBest home price: `+330` (Betfair Exchange). Best draw: `+290` (Betfair Exchange). Best away: `-106` (Betfair Exchange), then `-110`. Lowest margin: the exchange at 0.4%, then Pinnacle at 3.0%. The same book at the worst prices (888sport, William Hill) costs about 8% overround, so the choice of book moves the expected cost of a bet by several percent. The match total: Pinnacle `2.75` with `-106` over and `-104` under; William Hill `2.5`; `outcome.median_total` was `2.75` and the total went over (`over: true`).\n\nOpening versus closing for the home price at Pinnacle was `+649` to `+317`: the market moved heavily toward the home side's chance (Arsenal were still favorites at `-111`), which shows how much information gets priced in during the final days.\n\n## Reading Movement\n\n| Pattern | Reading |\n|---------|---------|\n| All books shorten the same side together | Information or heavy money; follow the sharpest book first |\n| One soft book lags the others | A stale price, a line-shopping chance, not a signal |\n| Draw price drifts while home and away hold | Often margin redistribution, not a view on the match |\n| Total moves 2.5 to 2.75 | Quarter lines: the book is shading, price the over and under at the stated odds |\n\n\n## Anti-patterns\n\n| Rationalization | Why It's Wrong | Do This Instead |\n|----------------|---------------|-----------------|\n| \"Compare home and away only\" | The draw holds about a quarter of the probability | Always show all three |\n| \"Best price at one book for all three\" | Best prices sit at different books | Choose per outcome |\n| \"Pinnacle open to close is a steady line\" | Compare `source`: ESPN and Odds API rows differ in timing | Report the source with each number |\n| \"Trust any row\" | Thin exchange snapshots can be garbage | Sanity check overround |\n| \"Median across books is a real line\" | Medians such as `2.88` or `0.13` are not postable lines | Use them for comparison, not as a bet |\n\n## Output Format\n\n```\n[Home] vs [Away] - [date], [competition]\nBest home: [price] @ [book]    Best draw: [price] @ [book]    Best away: [price] @ [book]\nLowest margin: [book] [x.x]%   Highest: [book] [x.x]%\nTotal: [line] ([over] / [under]) @ [book]\nMovement: [book] [open] -> [close], implied [x]% -> [y]%\nCredits: [n]\n```\n\n## What to Do Next\n\n| What You Found | Next Action | Skill |\n|----------------|-------------|-------|\n| Need true probabilities | Remove the margin | `odds-analysis` |\n| Want context for the match | Form, Elo, xG | `match-preview` |\n"
