Sometimes I was not aware when I'm emotion, and usually, I realized it when I've lost. so to control my emotion is learning from previous experience.
It is very difficult to cope with their emotions when it comes to finance and some aspects of earnings. First of all, this applies to gambling and then trading. Of course there is a person very much Already in the course of all matters and it is much easier for all to trade for example and the nerves in his place.
Its difficult indeed, to control my emotions in trading is that when I am losing I will cut my losses or selling it at losing price than to leave it and lose big time or wait several months again to let the price jacks up. Also, if trading is fast, I will leave my PC and do something else. But usually I trade only on small amount, so that when I lose it is negligible.
Yes, controlling emotions is a difficult task especially in gambling. we can not handle the situation when we are in long run loss or win. But in trading it is different, we can handle this, but sudden price fall will make us panic, and we sell our coins for a low price. If we control this, then we can make a good profit in trading.
