I've tried a few things. They all work in certain conditions. Range bound days are easy to print money if you can identify support/resistance levels early enough in the day, but those levels tend to be squishy so you can't use too tight of a stop loss, and can't be too specific with your entries. 

Trend days are my favorite. Just attack every little pullback and ride the trend. Those days don't happen often enough though. 

I tend not to have enough patience to stare at a screen and do nothing for days and days until I get the market conditions that I want.

Most days are choppy with shifting market conditions where by the time you define your levels the next swing invalidates them. It can be very frustrating.

I don't do a lot of TA. It's a craps shoot. Except for wedges. When price action started narrowing down into a tighter and tighter wedge it's usually going to break out and run soon. But a lot of that TA nonsense is just hoodoo voodoo. Astrology for men.
