The three big reasons for trading drawdowns according to renown trading Psychologist Brett Steenbarger:
1) They’re trading a strategy that doesn’t fit the present market;
2) They’re trading the right strategy, but their head isn’t in the game and they’re not following their strategy;
3) They’re trading the right strategy with a good mindset, but they’re employing the wrong tactics and thus not implementing their strategy the right way.
The may be so but I find the STOP the simplest most effective and reliable way to stop drawdowns.
