Resistance is a price area where sellers have repeatedly stepped in and absorbed buying, slowing or reversing an advance. Like support, it is best treated as a zone, because orders are dispersed and wicks often overshoot the level.
How it works
Resistance forms where past selling absorbed buying: price stalled, left upper wicks, or reversed. Returning to that band can bring the same reaction again.
A break is judged by closes. Consecutive closes above the zone confirm the resistance failed and that price is no longer being capped there.
Why it matters
Resistance defines the invalidation point for short ideas and the reference for targets on long ideas, which is how it becomes a risk decision.
Reading resistance as a zone stops you from exiting a trade just because a wick touched the level, then watching it continue to the target.
A simple market example
A stock repeatedly fails to close above $80 over several months, leaving upper wicks each attempt. A trader marks $80 as a resistance zone and waits for either a reaction down from it or a confirmed close above it before acting.
Common mistakes
Taking a short at resistance without waiting for reaction evidence, treating the zone as an automatic rejection.
Ignoring a confirmed close above resistance and staying short, even though the level has failed.
Frequently asked questions
Can resistance become support?
Yes. After a confirmed break, old resistance frequently flips and acts as support on the retest.
What is the best way to use resistance?
As a risk reference: stop above the zone for shorts, target reference for longs, and a defined point where your idea is wrong.
Is the first touch of resistance tradable?
Not usually. The first touch is often the least reliable; reaction evidence inside the zone matters more.
