Support and resistance are the two horizontal pillars every chart-reader uses. They are mirror images, not different concepts. Knowing what makes a level strong is the same exercise in both directions.
Support and resistance are not two different things; they are the same idea applied above and below price. Support is a price zone where buyers have historically stepped in with enough force to halt declines. Resistance is a price zone where sellers have historically stepped in with enough force to halt rallies. The mechanics, the strength criteria, and even the way they fail are mirror images of each other.
What makes both strong is identical: multiple touches (three is the conventional threshold for a "valid" level), recent rejections (more recent matters more), round-number gravity (humans cluster orders at psychological prices like 100, 500, 10,000), and higher-time-frame confluence (a level visible on the daily is stronger than one visible only on the hourly).
Both are zones, not lines. Treat every level as having some thickness — a few cents at the equity level, a handful of pips in FX, sometimes meaningful percentages in crypto. A level tested three times within a small band counts as one support (or one resistance), not three.
The most useful trick once any level breaks is role reversal: a broken resistance often becomes new support, and a broken support often becomes new resistance. That isn't magic — it''s the result of traders trapped on the wrong side of the level now defending their entries, plus new participants treating the broken level as the freshest reference point. The same mechanism produces the same outcome in both directions, which is why mature traders learn the two as one concept.
The hardest part for beginners is psychological: a level below the market feels safer than a level above the market, which leads to over-trading support bounces and under-trading resistance fades. The math is symmetric; the bias is human.
| Feature | Support | Resistance |
|---|---|---|
| Direction | Below current price | Above current price |
| Force at the level | Buyers defend | Sellers defend |
| Strength criteria | Multi-touch, recent rejection, round-number, HTF | Multi-touch, recent rejection, round-number, HTF |
| Best entry | Bounce confirmation (wick + close back up) | Rejection confirmation (wick + close back down) |
| Invalidation | Close below the zone | Close above the zone |
| On break | Often flips to resistance | Often flips to support |
| Common mistake | Trading every minor swing low as 'support' | Trading every minor swing high as 'resistance' |
When to use Support
Support matters when price is approaching a tested floor from above. The disciplined trade waits for evidence the floor is defended: a long lower wick, a bullish reversal candle, or simply a close holding within the support zone. Invalidation is a close below the zone — at which point the level has failed and the bullish thesis is dead. Pair support trades with a known resistance above to define a clean R:R target.
When to use Resistance
Resistance matters when price is approaching a tested ceiling from below. The disciplined trade waits for evidence the ceiling is defended: a long upper wick, a bearish reversal candle, or a close back inside the prior range. Invalidation is a close above the zone — at which point the level has failed and the bearish thesis is dead. Pair resistance trades with a known support below to define a clean R:R target.
Horizontal price zones where buyers (support) or sellers (resistance) have historically stepped in with enough force to stop or reverse a move. Multi-touch levels carry more weight than single touches.

A directional bias in price made visible by a sequence of higher highs and higher lows (uptrend) or lower highs and lower lows (downtrend). When that sequence breaks, the trend is in question.

A move in which price decisively closes through an established support or resistance zone, signalling a potential continuation or trend change. The close — not the wick — defines the breakout.

Three is conventional. Two is a working hypothesis; four-plus makes it well-known to other traders and therefore obvious.
No. Symmetrical mechanics. The asymmetry beginners feel is psychological, not structural.
A broken resistance becomes new support (or vice versa). The level itself doesn't change; the side defending it does.
Yes, but with weaker confidence than horizontal levels. Diagonal lines are subjective; horizontal levels are agreed-upon by more participants.
