Levels - Look for previous Resistance levels to become areas of support, Look for previous Support levels to become areas of Resistance.
Structure - Basic Elliott Wave Concepts. Look for An Impulse Leg making a new Higher High or Lower Low, then wait for a pullback to Level. Structure qualifies Identified Levels as Trading Levels.
Reaction - Once Level, Structure and Liquidity have been Established the final step is to see the market react at the Pre Determined Level.
Fractals - Markets are Fractal, I like to see the market react from a Level then drop 2 timeframes and watch for a second iteration (Level, Structure, Liquidity).
