How to find the levels price actually respects, why they flip roles on a break, and how to trade the reaction instead of guessing.

// key takeaways
▸ Support is where buyers repeatedly step in; resistance is where sellers do.
▸ The more reactions a level has, the more it matters.
▸ On a clean break, support becomes resistance and vice-versa (role reversal).
▸ Trade the reaction at the level, not a naked guess in open space.

What a level really is
A support or resistance level is simply a price where the order flow has repeatedly turned. It is not a magic line — it is a zone where enough buyers or sellers have historically committed to change direction. Draw levels off obvious swing highs and lows and off prices that have been tested more than once.
Role reversal
When price closes decisively through resistance, that old ceiling often becomes the new floor — buyers who missed the breakout defend it on the retest. The same works in reverse for broken support. This flip is one of the highest-quality entries in technical analysis because it gives you a defined level to lean your stop against.
How to trade it
› Mark the zone, then wait — do not front-run the level.
› Look for a reaction: a rejection wick, a lower-timeframe reversal, or a volume spike.
› Enter on confirmation with a stop just beyond the zone, where your idea is proven wrong.
// common mistakes
✕ Drawing dozens of lines until every price is 'a level'.
✕ Placing stops exactly on the level where liquidity gets hunted — give it room.
✕ Assuming a level holds forever; every level eventually breaks.
