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.

Firm presets show the date they were last checked against the firm's own pages. If your firm or product is not listed, choose Custom rules.
