Expectancy = win rate × average win − loss rate × average loss, in R (multiples of what you risk). At 1% risk, +0.2R per trade is about +20% over 100 trades before compounding.

Flowsense computes expectancy, R and profit factor for every setup, symbol and session from your own trades, so you know which ones to keep.

FAQ

What is trading expectancy?
The average result per trade in R (multiples of the amount risked): win rate × average win − loss rate × average loss. Positive expectancy means the strategy makes money over many trades.
What is an R-multiple?
Profit or loss divided by the initial risk. If you risk $100 and make $250, the trade is +2.5R. Measuring in R lets you compare trades of any size.
What win rate do I need to break even?
Average loss ÷ (average win + average loss). With 2R winners and 1R losers you break even at 33.3%.
