Why I always lose insanely after I make large profit?

I made 1200USD yesterday and I lose 900USD today. Actually my daily max loss allowable is 600USD and I have a lose trade when I lost 580USD lol.

I don’t really think it’s the problem of overconfidence, it always comes together with overtrading but I only take 4 trades today, 1Win2Loss and 1 Huge loss because of slippage.

Is like a curse, once I make over 1000USD in one day I will always lose them in following day immediately.
