I have made a schoolboy error in the past of leaving my profit in my trading account, until i learnt the hard way. I started losing bits of it until i lost everything.
Here are the list of things u can do
1. Withdrawal immediately
2. Leave the money in your trading
3. Allow the broker to take their money back...
Whatever you do avoid number 3.
i just leave the money to compound. It is a form of delayed gratification for me.
Always pay the trader. Withdraw your profit and pay yourself for a work well done. It helps with your psychology.
