Topstep drawdown calculator

Topstep Trading Combine (futures): The Maximum Loss Limit (MLL) trails your end-of-day balance upward, never moves down, and locks once it reaches your starting balance. Open (unrealized) losses count in real time.

How "safe risk per trade" is worked out

It takes the room between your equity and the binding floor (the closer of the max-loss and daily-loss limits), uses only the share you choose (50% by default), and splits it across the number of full stop-outs you want to survive in a row (2 by default). This is a conservative planning aid, not a prediction or a recommendation.

Topstep rules in plain English

Monitored in real time, but the floor only updates at the end of each trading day.
Both realized and unrealized P&L count toward the limit.
On breach the Combine account is liquidated and you must Reset before funding.
