Many traders focus on having as many winning trades as possible. But it actually doesn’t matter how many winning trades a trader produces, all it comes down to is the bottom-line of are the accumulated profits per period bigger than the total losses? So even if a trader generates 99% little losses but then 1% large profits that well outperform the losses, than they have still performed better than the trader who proudly announces that they have a 90% profit loss ratio with 10% of losses outweighing the profits.
The examples below is a great illustration how focusing on % winning trades can be detrimental. Trading System 2 is the better system because it generates more profits. Trading System 1 is all about ego and results in losses. System 2 is all about mathematics.
