I've found that once you do thorough statistical analyses of price action patterns in various context, you'll find one or more positive expectancy setups. (By "setup" I mean a price action pattern within specific context.)
My earliest forays into trading strategies involved indicators. This was moderately useful, but without an understanding of price action, I put too much faith in indicators to the extent that I traded my opinion about what price should do instead of making my trading decisions off what price was actually doing.
Once I learned about price action, I realized that indicators are unnecessary, though they can be very useful in helping define context.
In a nutshell: Learn about price action first (Brooks, Volman, Beggs, etc.), then investigate whether any indicators are useful or even necessary at all.
And definitely trade in a sim environment until your trading is as relaxed, automatic, and consistent.
