Support vs Resistance — same idea, opposite direction

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.
