as a trader, losing one or two trades is part of the game but sometimes losing everything that had been accumulated for weeks, months is very painful and there is need to know whether it's due to ignorance or insufficient trading skill. Acquiring sufficient trading skill is very important in trading which can also help to get good results.
I usually ask myself questions whenever I have consecutive loses in trading, trying to know where I'm getting it wrong. This had helped me many times to get more trading knowledge that had improved my entire trading.
