Loss aversion bias derives from the prospect theory. Humans have a funny way of evaluating their gains and losses, along with comparing their perceived meanings against each other. For example, when considering our options before making a choice, we are more willing to give preference to a lower possible loss over a higher possible reward. Fear is a much more powerful motivator than greed. In practice, a trader with a loss bias is more akin to cutting profits when they are still low, while allowing bigger drawdowns.
It's easy for traders to feel confident in their ability to remain calm and collected during their trading sessions before the market opens. However, once the clock starts it's a different story. When faced with real financial decisions, it's very easy for emotions to come into play. We can't avoid our emotions, but we can learn to work around them.
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.
Probably the most important tip I can give you is to accept the fact that some trades are just going to lose. There is nothing you can do about that. Every trader has losing trades. It is part of the forex game, forex is a game, there are buyers and sellers, and our job is to pick the right side. We can't always do it, but if we enter trades with at least 3 strong technical & fundamental reasons, then we give ourselves the best chance to succeed in the long run.
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 blender company could have reduced this risk by shorting the euro and buying the USD when they were at parity. That way, if the dollar rose in value, the profits from the trade would offset the reduced profit from the sale of blenders. If the USD fell in value, the more favorable exchange rate will increase the profit from the sale of blenders, which offsets the losses in the trade.
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.
