no but seriously, the most effective strategy is buy and forget

and your gut feeling that you have made right investment

and wait for it to go up

which is why i don't do intraday, just buy with delivery and hold
I want to believe you are talking about bitcoin, even though you didn't explicitly mention, if it is bitcoin, then you are correct; i am a long term bitcoin investor, so i just buy and hodl for the long time while i also accumulate along the way. But if you have other coins in mind other than bitcoin, then i'd not advise this, altcoins are very risky and you better not buy them and forget it, lol.
That said, i am pretty sure this does not help OP because he is an active trader, i don't know of any strategy that would help you get profit in trading and i can only advise on hodling bitcoin which i think is better than trading.
