Has your edge changed? Ask your own trades.
Drop the trade history from your platform. A change-detection test tells you whether the recent losses are noise or a real shift, and how much room your prop firm's limits have left.
Runs in this tab. Your trades are never uploaded.

Know the day it changes. Not the month after.
Strategy Vitals Live runs this test on your live trades every day and alerts you when the watch or alarm level is crossed, with your prop firm's limits alongside. Leave an email and we will tell you once, when it opens.
How it works
A CUSUM, the test factories use to catch a process drifting off spec. The same test, with the same levels, runs on our own live gold bot every day.
Baseline
Your backtest numbers, or the first half of your trades: win rate, average win, average loss. From those comes the break-even win rate.
Edge health
Each tested trade moves a running edge-health line that starts at zero. A loss pulls it down, a win lifts it back, scaled by how far the baseline sits above break-even. It never rises above zero.
Verdict
Watch at −2.5, alarm at −4.5. It cannot tell you why the edge moved or whether it returns. It is a statistic about your own trades, not advice.
