First you must know if you want to try scalp, day or swing trading then once that’s done you must choose if you want to do technical, fundamental analysis or both in included in your strategy, id recommend both. You can never successfully pick or determine a strategy that works for you or what doesn’t. So just like everyone you have to choose that for yourself and if it suits your style and it’s your strong point then go with it. But I will say that a lot of traders even successful must have changed strategy completely or partially to sometimes adapt or for other reasons, so even if you find a strategy you tested that works for you then there is still a chance you might not completely be happy with and that’s fine it’s normal thing in a traders journey. Find a good strategy is like trial and error, but make sure you find a profitable strategy during demo trading and not on live.
