If your trade size is too large it means you are trying too hard, being greedy and you are hoping to make unrealistic amounts of money in the short-term. Greedy traders destroy their accounts. Trading is about making small amounts of money in the long term.
Money management is the backbone of successful trading. Without it, even the best strategies will fail. Control your losses & the profits will take care of themselves.
@daytradesignals I have 2 accounts, the one in which I will take 3 swings trades for the week on 3 chosen assets. Then I have a account which I'll day trade another 3 assets with a pivot based breakout strategy
