How to Verify an Arbitrage Trade Before Placing
A checklist for evaluating a ready arb: market, odds, limits, settlement rules, bankroll split and red flags.
Don't place blindly
A pre-built trade saves time but doesn't remove your responsibility to verify it. Odds change, limits vary by account, and settlement rules can differ even on similar-looking markets.
Treat every trade as a hypothesis: it may be valid, but you need to confirm it against a checklist before placing.
Verify the market and settlement rules
Confirm both sides cover the same event and compatible markets. Pay close attention to tennis, esports, handicaps, totals, overtime inclusion, pushes, and early event termination.
If settlement rules differ, a mathematical arb may be illusory. For example, one bookmaker may include overtime while another settles on regular time only.
Check live odds and limits before placing
Don't calculate the trade on stale odds. Open both markets, confirm the current odds and max stake, then calculate your stake split. Only then place.
If the limit on one side is below your required stake, reduce the total trade size or skip it. Don't cover positions asymmetrically without understanding the risk.
Evaluate red flags
Very high yield, low-liquidity market, unknown bookmaker, unusual bonus conditions, frequent withdrawal complaints, and sharp line movement — any of these are reasons to stop and recheck.
The goal isn't to take every arb. It's to select situations where execution risk doesn't consume the mathematical edge.
