However, this can steer you away from a carefully planned trading strategy. Even worse, it could cause you to make rash decisions, with the hope of turning that losing trade around, causing you to lose much more money than you would have if you had just left it to play out. Instead of focusing on the long term plan, your mind wants to focus on making the best out of this short term losing position.
The problem is that this is where traders are most likely to succumb to overconfidence bias. It's not uncommon for traders to complete a winning streak and then believe that they can't get anything wrong in the future. To believe this is of course unwise, and is only going to end in failure. Make sure you always analyse your trading sessions and look at your wins and losses in detail.
