The minimum record
Identify the innings, score, wickets, legal-ball count and market period when available. A price without that context cannot support a reliable historical comparison.
Overs are not decimals
Cricket notation such as 10.3 refers to ten overs and three legal balls, not 10.3 arithmetic overs. Do not feed that display directly into a run-rate calculation.
Acceptance matters
A market can suspend between deliveries. The accepted price and selection on a receipt matter more than a quote displayed before an action.
Our observations are dated
This calendar is not a ball-by-ball live trading service. An old snapshot never becomes live merely because the match is still being played.
