How to use the trading calculators
Start with position size so one stop-out risks only the percentage you planned. Use the risk/reward calculator to compare the distance to your stop and target, then check the breakeven win rate before entering. After a sample of trades, use profit factor and win rate with expectancy to review whether the edge is repeatable. Options traders can add strike, premium, contracts, and expiry to see the payoff range. These browser-based tools do not send your inputs anywhere and support your trading plan; they are not investment advice.
