Over trading is one of the major reason of having loss in Forex trading. We should avoid over trading.
Some trader start over trading when they make two more consecutive win to make more profit but the matter of regret is that most of them loss all the profit with balance because of this over trading.
Again some trader over trade on anger when they face consecutive losses.
According to me if you win three trade consecutively stop trading and be happy with profit and if you face three consecutive loss stop trading immediately and go for refreshment.
