Support is a price area where falling markets repeatedly stop falling; resistance is where rallies repeatedly stall. These levels exist because memory and unfinished business concentrate there — trapped buyers waiting to exit breakeven, limit orders from those who missed the last move, stops clustered just beyond. Nearly every strategy on this site is, underneath, a way of trading these zones. Master this one first.

Finding levels that actually matter

Three rules separate meaningful levels from chart clutter:

1. Zones, not lines. Price reverses in areas, not at exact ticks. Draw a band around the cluster of highs/lows, roughly the width of an average candle's wick.
2. Touches + reaction strength. A level that has reversed price twice with strong moves away from it beats one with five weak grazes. The violence of the reaction shows how much the market cares.
3. Higher timeframe wins. A daily level outranks a 1H level. Mark levels top-down: weekly/daily first, then refine intraday. If your chart has more than 4–5 zones, you're drawing noise.

Role reversal is the concept that unlocks the rest: broken resistance becomes support, and vice versa. The trapped traders from the break defend the level from the other side. Retest entries — the core of the breakout strategy — are role reversal in action.

Strategy 1: The bounce

• Setup: established zone (2+ strong reactions), price approaching it with the higher-timeframe trend (buying support in an uptrend, shorting resistance in a downtrend)
• Entry trigger: rejection candle at the zone — hammer, engulfing, or morning star
• Stop-loss: beyond the far side of the zone
• Target: the opposite level; take partials at 2R
• Skip: the third-plus consecutive test of a level — each test consumes the orders defending it, and repeatedly hammered levels tend to break

Strategy 2: The break and retest

• Setup: the zone breaks with conviction — a full candle close beyond it, ideally on expanded volume
• Entry: on the retest, when price returns to the broken level and holds it from the other side (rejection candle again)
• Stop: beyond the reclaimed zone
• Target: the measured move or next major level

How to backtest it

Level-drawing is a judgment skill, which makes this the perfect manual backtest:

1. In chart replay, pause at a random point in history and mark your zones before playing forward — the hidden future keeps you honest.
2. Play forward; trade only bounces and retests at your pre-marked zones, 50 trades.
3. Grade the levels themselves: which of your zones did the market respect? Within weeks your level selection tightens dramatically — that improvement is the strategy.

Common mistakes

1. Exact-line thinking — stopped out by the wick that pierces your line by 0.2% before the level holds perfectly.
2. No trigger — a limit order at a level is a hope; a rejection candle at a level is a trade.
3. Counter-trend bounces — support in a freefall is a suggestion, not a floor.
4. Trading every touch of a fading level — levels wear out; fresh, strongly-defended zones pay best.

FAQ

How do I identify strong support and resistance?

Look for zones with at least two sharp reversals, visible on the daily or 4H chart, ideally coinciding with round numbers or prior all-time levels. If you have to squint, it isn't one.

Why does price break support then reverse immediately?

Stop hunts: clustered stops just beyond obvious levels are liquidity, and fast money pushes through to trigger them before the real move. It's why zones beat lines, why closes matter more than wicks — and why the failed break itself is a tradeable signal (see smart money concepts).

Does support and resistance work in crypto?

Exceptionally well — crypto's retail-heavy flow respects obvious levels and round numbers strongly. Replay any BTC era and you'll watch the same zones get hit, defended, broken and retested for months.
