What's my total account drawdown if all my open positions dropped at the same time?

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.
