There are two parts to fixing any psychological problems:

1. Recognizing that it exists
2. Accepting it so you can move on
In trading, this is where it’s so crucial to take responsibility for your own actions because it induces change and you can start making improvements. If you don’t recognize and accept a problem, then you won’t get anywhere!
What are some of these issues  ? Here are a few along with their causes and/or effects:
1. Anger over a losing trade – Traders usually feel as if they are victims of the market. This is usually because they either 1) care too much about the trade and/or 2) have unrealistic expectations. They seek approval from the markets, something the markets cannot provide.
2. Trading too much – Traders that do this have some personal need to “conquer” the market. The sole motivation here is greed and about “getting even” with the market. It is impossible to get “even” with the market.
3. Trading the wrong size – Traders ignore or don’t recognize the risk of each trade or do not understand money management. There is no personal responsibility here.
4. PMSing after the day is over – Traders are on a wild emotional roller coaster that is fueled by a plethora of emotions ranging throughout the spectrum. Focus is taken off of the process and is placed too heavily on the money. These people are very irritable akin to the symptoms of premenstrual syndrome.
5. Using money you can’t afford to lose – Usually, a trader is pinning his/her last hopes to make money. Traders fear “losing” the “last best opportunity”. Self-discipline is quickly forgotten but the power of greed drives them, usually over a cliff.
6. Wishing, hoping, or praying – Do this in church, but leave this out of the market. Traders do not take control of their trades and cannot accept the present reality of what’s happening in the market.
7. Getting high after a huge win – These traders tie their self-worth to their success in the markets or by the value of their account. Usually, these folks have an unrealistic feeling of being “in control” of the markets. A huge loss usually sobers them up pretty quickly.
8. Adding to a losing position – Also known as doubling, tripling, quadrupling down, typically, this means that the trader does not want to admit the trade is wrong. The trader’s ego is at stake and #6 comes into effect as the trader is hoping the markets will “work in their favor”.
9. Compulsive trading – Similar to #2, except these traders have an addiction to trading and quite possibly gambling issues. They need to constantly be trading, even if there is no rational reason to do so. They are always excited whether they win or lose.
10. Afraid of “pulling the trigger” – This usually means that the trader does not have a system or approach already in place. They have not calculated risk/reward and many times, these trades are unplanned. This also comes after a string of losses. They don’t want to be “wrong again”. There is no trust from within.
11. Over-thinking or second guessing – Similar to #10, but these people are usually looking for a “sure thing”, when they clearly don’t exist. Losing is not recognized a normal part of trading and the risks and unknowns of trading are not fully accepted.
12. Limiting profit or getting out too early – These traders have poor self-esteem. This is a direct effect of believing that the profits were undeserved. Usually a trader is stressed over a trade for some reason and closing the position quickly eliminates the anxiety. Usually, there is a fear of “giving back” those gains.
13. Fear of being stopped out – Traders fear failure and the pain from taking losses is great. Here is another instance where the ego is at risk. They must always be correct or suffer a feeling of “let down”.
14. Not following your system – This is a trust and follow-through issue. Perhaps the trader didn’t test it enough, or it recently produced a string of losses, casing some doubt. Your faith in the system is broken. Not only do you not trust the system, you can’t even trust yourself with picking one that works for you.
15. Following other traders (indiscriminately) – These traders do not have a system. They are also limited in trading knowledge. They feel that they will become winners if they simply “follow” someone. These trades are usually impulsive.
The key to all things is creating balance. This means that if you are winning or losing, you should not care. When you finally recognize and accept each of these common pitfalls, you’ll be well on your way to acquiring the trader’s mindset.
