Quoted odds versus obtainable prices: the execution gap

A practical checklist for quote timestamps, available size, price changes and settlement terms before acting on tennis research.

A screenshot records a moment

A displayed price is evidence of what a screen showed at a particular time. It does not establish that every subscriber could place a bet at that price. Historical examples, indicative quotations and a currently available offer should be labelled separately. None of the examples here is an official selection.

Check the market, side and timestamp

Confirm the exact match, selected player and match-winner market. Record the forecast time separately from the odds-verification time and scheduled start. If the match is delayed, withdrawn or moved, recheck the selection rather than carrying an old quote forward without review.

Available size changes the question

An exchange headline price may cover only a limited stake. Review the available amount and the prices beyond it; the average obtained across several fills can differ from the first price. A displayed bookmaker price may also be subject to acceptance and limits. Never report a matched stake or obtainable price without evidence.

Price movement can change the decision

For illustration, a 60% probability estimate at decimal odds of 1.80 gives 8% theoretical expected return before costs. At 1.60 it gives −4%. Both calculations depend on the probability estimate being accurate. Use the approved minimum-price rule; do not chase a move or substitute a new selection.

Compare settlement terms before comparing returns

Check the provider’s applicable retirement, withdrawal and void rules for that market. Commission and other applicable costs also matter. Two identical headline prices need not produce identical settlement. Keep these assumptions with the original record, and retain corrections separately.

What a useful research alert contains

Selected player and opponent; tournament and surface; scheduled start; forecast timestamp; model information where verified; reference price, provider and quote timestamp; and the applicable execution rule. Where a field cannot be verified, say so. A missing or stale price can justify waiting or passing.
