when asked the reasons behind their losses they have always responded by saying this,( bad luck).
Bad luck? Well for me it means he rely on his luck when it comes trading and don't have enough knowledge and strategy in order to win and to minimize losses.
If that so, or if i am on that situation, probably i will stop trading because surely you will end up massive losses afterwards.
Summary: Your profit must be greater than your losses if your a good trader so trade with wisdom.
Correct, that's why all traders must have risk management so that despite of losses you can still regain and have a profits at the end of day of trading.
