The core idea
Support is a price zone where buyers have repeatedly stepped in (a floor). Resistance is where sellers keep showing up (a ceiling). They are areas, not exact lines.
How to draw them
- Find prices the market has touched and reacted to multiple times.
- Use both bodies and wicks, and treat each level as a band, not a pixel.
- More touches + higher volume = a stronger level.
Role reversal — the pro move
When price breaks resistance, that old ceiling often becomes the new floor (and vice-versa). Watching old resistance flip to support is one of the cleanest entries in all of TA.
Why it works
Levels are memory. Traders remember where they got hurt or paid — and place their orders there again.
