The main question is, do you have an edge, do you make money? If you do, then good, do whatever you are doing. If you don't, then I would recommend that you try a higher time frame, even if you have to trade something else in order to accommodate your account size, like individual stocks, micro ES...I don't have 6 figure account... 15 minutes even 5,
Is to much. High leverage market, small account, big expectations, I must act close to price and orders...
I find that I lose money very consistently on anything under 5m time frame.
