Mostly stuff based on highs and lows. Learn geometrics for high probability patterns, 50% areas between any two points of interest and time and sales.

Looks like you are a newcomer to technical analysis. If you start without relying on stochastics, rsi, macd, cci, ergodic, smi and any of that lagging crap, you will already start with an edge because you will learn to be faster than the typical daytrader. Don't let any of the fans infect you with divergence either, divergence is a product of the imperfection of the indicator which leads to results as good as 50% or also commonly known as flipping a coin.

I use price action and momentum indicator (cci) for entries and price action only for exits. I trade of constant volume bars. If interested read the thread " why people use odd tic, volume and range bars"
