for the OP, i suggest you first figure out what time frame you prefer (day, swing, position) b/c that should dictate your strategy not the other way around.
if it's swing trading as an example come up with a plan for how you will enter, exit w/ a loss, exit w/ a profit and how much to risk on each trade. do not proceed under any circumstance unless you have each of these things WRITTEN DOWN. trust me on this one. it's fine to be discretionary vs systematic (each has plusses and minuses) but just know what you're looking for for each setup and stick to it.
there are so many strategies (mean reversion, trend following, etc) and ways to implement it (futures, options, stocks, etc) and this is just something you have to figure out what you want to do and what fits your personality and risk preference (e.g. if you're starting out trading spy instead of ES).
