Read the amount and the reason together
A void amount without context cannot show whether an order was corrected, cancelled or removed for another reason. Preserve the submitter’s explanation in the service-report workflow and review it alongside the venue and trading date.
Compare void ratios within the same reporting window
Daily, MTD and YTD percentages answer different questions. Use revenue from the same period as the denominator. Comparing a single day’s void amount with monthly revenue understates the daily control signal.
Escalate patterns rather than isolated numbers
Repeated reasons or amounts can justify a training or process review. A dashboard flag should lead to examination of the underlying reports, not an unsupported accusation against a staff member. Missing days can also distort comparisons.
