How this is calculated
This assumes every listed position drops by the same percentage at the same time, the way a broad market selloff or a shared sector or macro event can hit correlated positions together, not the way independent, uncorrelated positions normally behave.
Total drawdown equals the sum of each position's dollar value multiplied by the move percentage. Percent of account lost divides that total by your account size.
This is a stress test, not a prediction. It shows what a simultaneous move would cost if it happened, it doesn't estimate how likely that scenario is.
If this number is larger than you expected, it usually means more of your open positions are correlated with each other than your per-trade risk limits accounted for on their own.
