If you are emotional then don't participate in trading because that time you are unable to use strategies and to make profitable commitment. Trading is fraught with danger and if you make commitment emotionally then it become waste of your time and money.

If you think that market is not good then forget your losses for some time because this habit of forgetting will be a cause of avoidance from future full of regression. It is not necessary that if you are trading then you cannot leave it but its up to you that when you think that is is profitable for you then continue it and if you find it good to get benefit then leave it for sometimes.
