How do I size a trade from the risk instead of guessing?
Trade › the order ticket › Risk-based sizing (auto)
Switch on Risk-based sizing (auto). Enter the share of the account you accept losing in Risk per trade and the Stop distance; the ticket computes the Position size so that a stopped trade loses exactly that amount. Use size copies it into the order. The block also shows the money at risk, the reward at target, and the break-even win rate.
Step by step

Good to know
- Breakeven win rate is the share of trades that must win for this Reward : Risk to come out flat. Your win rate and Expected value below it come from your own journal history, not from a guess.
- The app never picks the percentage for you. The guide on how much to risk explains how to choose one.
