How to read these numbers

Max drawdown floor

This is the lowest your account balance can ever reach before you fail the evaluation. For trailing drawdowns, the floor moves up as your equity grows — so a good session tightens your margin going forward. For static drawdowns, the floor is fixed at the starting balance minus the max drawdown and never changes.

Daily loss limit

The maximum P&L loss allowed in a single trading session. If your position hits this number on open trades intraday, stop trading for the day immediately. Some firms measure this on realized trades only; others include open floating losses. Check your firm's exact definition.

Safe risk per trade

The recommended stop-loss size per trade such that you'd need a long consecutive losing streak to breach the drawdown floor. A common rule of thumb is sizing so a single loss is 2–5% of your max drawdown. The calculator shows how many consecutive losers you can absorb at your chosen risk size before hitting each limit.
