The worst day, measured twice

Closed trades and account equity can describe different daily losses.

Verdict: a closed-trade total can hide how far the account moved while positions were open. Logan booked a 30,247.94 USD loss on its worst closing day.

Why the numbers differ

The closing-day figure assigns a trade's full result to the date it ended. A position may build a loss over several days and place the entire realised amount on only the final day.

The equity view follows the account during the run. It can show pressure from positions that are still open, but its daily result depends on the account level carried into each day.

Logan shows the opposite shapes

Logan's second-worst closing day lost 0.24 USD. That sharp gap means the realised record concentrates nearly all of its daily damage in one event rather than showing a sequence of similar closing days.

The equity record tells a broader story. Its deepest measured point was 68,317.63 USD after a previous peak of 100,636.82 USD, while no single intraday drop matched the one-day realised loss.

Which number should you use?

Use closed-trade totals to understand when losses became final. Use equity drops to judge the pressure the account experienced while positions were still alive. A daily-loss rule normally cares about the second view.

Neither view is a forecast, and one cannot replace the other. Read them together before accepting a claim about a strategy's worst day.

The window the vendor could not see: 13 of 26 audits have one at all (September 2026)

Every audit cuts its trades at the release date and at the date the audited build shipped (until 29 September at the vendor's last update), and only the piece behind that cut is guaranteed unfitted for that build. 13 of the 26 default audits in our catalog on 4 September 2026 carry such a window at all, its median is 46 days and 47 trades, and seven sit at exactly zero because the vendor shipped an update after our test had ended. Six of the thirteen read better out of sample and six read worse, on samples as small as 2 trades.
