Fear – Traders become fearful of entering the market usually when they are new to trading and have not yet mastered an effective trading strategy like price action trading (in which case they should not be trading real money yet anyways). Fear can also arise in a trader after they hit a series of losing trades or after suffering a loss larger than what they are emotionally capable of absorbing. To conquer fear of the market, you primarily have to make sure you are never risking more money than you are totally OK with losing on a trade. If you are totally OK with losing the amount of money you have at risk, there is nothing to fear. Fear can be a very limiting emotion to a trader because it can make them miss out on good trading opportunities.
Euphoria – While feeling euphoric is usually a good thing, it can actually do a lot of damage to a trader’s account after he or she hits a big winner or a large string of winners. Traders can become overly-confident after winning a few trades in the market, for this reason most traders experience their biggest losing period’s right after they hit a bunch of winners in the market. It is extremely tempting to jump right back in the market after a “perfect” trade setup or after you hit 5 winning trades in a row…there’s a fine line between keeping your feet grounded in reality and thinking that everything you do in the markets will turn to gold.
Revenge – Traders experience a feeling of wanting “revenge” on the market when they suffer a losing trade that they were “sure” would work out. The key thing here is that there is no “sure” thing in trading…never. Also, if you have risked too much money on a trade (starting to see a theme here?), and you end up losing that money, there’s a good chance you are going to want to try and jump back in the market to make that money back….which usually just leads to another loss (and sometimes an even larger one) since you are just trading emotionally again.
This is great, as the markets are open so long, we can enter or close a trade whenever we need to, whereas if you were trading stocks on the NYSE you can only trade during market hours, and once the market is closed you have to wait until the next trading day to trade your position. This forex help tip can really save you when there is a big unexpected political or news release and you need to close your position right away.
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.
