How it works
The formula.
Win rate = winning trades ÷ all trades; a result of exactly zero is a trade, but neither a win nor a loss. Profit factor = the sum of the wins ÷ the sum of the losses. Expectancy = the total ÷ the number of trades, the same as win rate × average win − loss rate × average loss. Example: 250, −100, 180, −120, −90 and 300 are six trades, three of them wins: a 50% win rate, a profit factor of 730 ÷ 310 = 2.35 and an expectancy of 70 a trade. A few dozen trades say little about the next one.
A calculator works out one trade or one list. Stocka’s trade journal keeps the real numbers for you: every buy and sell with its fees, your average cost, and your realised and unrealised P&L, on iPhone, iPad and Mac. The journal is free.
