Win rate
Win rate is the percentage of winning trades out of the total. It is never enough to judge a strategy without the size of wins and losses.
If you win 60 trades out of 100, your win rate is 60%. It is the figure signal sellers push hardest, because it is flattering and easy to understand.
But an 80% win rate can hide a losing strategy if the losses are five times bigger than the wins. Conversely, many trend followers make money with 35% to 40% winning trades, thanks to wins far larger than their losses.
Always read this number alongside the average win to average loss ratio, expectancy and profit factor, over a large enough sample.
