Comparison
Support vs resistance
Support and resistance are the same phenomenon viewed from opposite sides: a price area where the market has repeatedly changed its mind. Support is a floor under price, where falling prices have tended to stall because buying interest keeps emerging. Resistance is a ceiling, where rallies have tended to fade as selling interest appears.
| Support | Resistance | |
|---|---|---|
| Position relative to price | Below current price | Above current price |
| What halts price there | Buying interest emerging | Selling interest emerging |
| Typical origins | Prior lows, round numbers, heavy-volume zones | Prior highs, round numbers, trapped buyers |
| When broken decisively | Often flips into resistance | Often flips into support |
| Strengthened by | More touches with reactions, higher volume | More touches with reactions, higher volume |
| Weakened by | Each retest chips away the resting orders | Each retest chips away the resting orders |
The role flip
The most useful idea in this pair is the flip: when a level breaks decisively, its role often reverses. Old resistance can act as new support because breakout buyers defend their entries and late sellers look to exit flat, clustering orders at the same price. The reverse holds for broken support. That is why chartists watch the retest of a broken level as closely as the break itself.
Zones, not lines
Neither support nor resistance is a precise number. Orders cluster in areas, so wicks routinely pierce a 'level' that then still holds on a closing basis. Our guides teach reading levels as zones, weighting closes over wicks, and counting genuine reactions — and always with the caveat that every level fails eventually; a floor holding in the past is never a promise about the future.
Frequently asked questions
Can a level be support and resistance at the same time?
At a single moment, no — the roles are defined by which side price is on. But the same price area frequently serves both roles across time, flipping when it is decisively broken. Those long-memory levels are the ones chartists mark first.
How many touches make a level valid?
Convention says at least two reactions to draw it and a third to confirm it. But there's a trade-off: each additional test also consumes the resting orders defending the level, so a heavily-tested level can be simultaneously well-proven and close to giving way.
Do support and resistance work on every timeframe?
The mechanics are the same from one-minute to monthly charts, but levels drawn on higher timeframes reflect more participants and more volume, which is why they're generally treated as more significant.
