You need to not over-trade. Most traders trade way too much. You need to know what your trading edge is with 100% certainty and then ONLY trade when it’s present. Once you start trading just because you “feel like it” or because you “sort of” see your trading edge…you kick off a roller coaster of emotional trading that can be very hard to stop. Don’t start over trading and you will likely not become an emotional Forex trader.
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.
