Trading calculators
Four small calculators for numbers traders look up constantly. Each one states its formula in full, shows a worked example, and says plainly what the number does not tell you. Nothing is stored and nothing is sent anywhere.
Win rate calculator
Work out win rate from a count of winning and losing trades, and see the loss rate alongside it. Free, instant, nothing stored. The formula is shown in full.
Open → CalculatorRisk/reward calculator
Work out the risk-to-reward ratio from entry, stop and target, and the win rate that ratio needs to break even. Free, instant, nothing stored.
Open → CalculatorProfit factor calculator
Work out profit factor from gross profit and gross loss, and see what the result means. Free, instant, nothing stored. The formula is shown in full.
Open → CalculatorTrading expectancy calculator
Work out expectancy per trade from win rate, average win and average loss. Free, instant, nothing stored. The formula and a worked example are shown in full.
Open →Why these four
These are the metrics that appear in almost every trading-record review, and the four of them interlock. Risk-to-reward sets the win rate you need merely to break even. Win rate on its own says nothing about whether a record made or lost ground, because it ignores the size of each result. Profit factor adds that size back in. Expectancy combines rate and size into a single per-trade average.
Read in that order they answer one question: did this record do better or worse than its own structure required? A calculator cannot answer whether a strategy is sound, and none of these pages claims it can.
