Fixed Odds Betting Margin Lab
Overround · break-even · executable prices
Fixed odds betting is the classic bookmaker market. Bookmakers embed margin (overround). Your edge must clear that tax. Break-even hit rate is approximately 1 ÷ average decimal odds.
Margin
If both sides are 1.91, each implies ~52.4%; sum ~104.7% → about 4.7% overround.
Break-even
At average odds 1.95, break-even hit rate ≈ 51.3% before considering edge.
Value test
Stake only when estimated probability exceeds implied probability by your minimum threshold.
