Common error to avoid when you day trade, I modified some to reflect my own opinion.
1. Revenge trading, trying to get back a trade that has been lost or chasing a trade.
Ergh.
This is one of my weaknesses. One of the mostly used by my brain and it is like a black out moment. Nothing else to think but just to get it back. The losses have been larger for me because of this and I though I could get it back by just a moment and yet nothing comes back, profit or ROI.
Do not let it get the best out of you. Control is a must.
Somehow this is the reason that is why I think trading is also a gamble.
