How to read your results

Every number on the results page describes your past trades under each evaluation's current rules. None of them is a forecast.

Pass rate

For each evaluation, the replay starts a fresh account on every trading day in your history and runs it forward until it passes, fails or runs out of trades. The pass rate is the share of those start days that passed.

Start days near the end of your file can run out of trades before they finish. Those are left out, because the ones that do finish early are mostly quick failures and would drag the rate down unfairly.

Likely range

Start days next to each other share most of their trades, so 800 start days are not 800 independent tries. The likely range is a 95% Wilson interval sized by the number of back-to-back attempts your history holds: buy on day one, pass or fail, buy again the next trading day, and so on. A rate from 6 such attempts gets a wide range; a rate from 200 gets a narrow one.

Results are ranked by the low end of that range, so a 100% from two attempts doesn't outrank a well-measured 60%.

Expected evaluation cost

The price you'd expect to pay to pass once: the first purchase, plus one reset or repurchase for each expected failure, plus any activation fee. Monthly plans are billed for the months the attempts would take. The firm's list price is used unless you enter the price you'd pay; firms run coupons constantly. This is the cost to pass the evaluation, not to receive a payout.
