Compression in Price Action — Complete Guide

What is Compression?

Compression occurs when price makes progressively smaller ranges — lower highs pushing into support, or higher lows pushing into resistance. It represents building pressure that will eventually release in an explosive directional move.

How Compression Forms

Bullish Compression (Into Resistance):

Resistance ─────────────────────────────
              ╱  ╱  ╱  ╱  ╱  ← Higher Lows pushing UP
           ╱  ╱  ╱  ╱  ╱
        ╱  ╱  ╱  ╱
     ╱  ╱  ╱

Buyers getting more aggressive (higher lows)
while sellers hold at resistance.

Eventually: EXPLOSIVE BREAKOUT ABOVE

Bearish Compression (Into Support):

Sellers getting more aggressive (lower highs)
while buyers hold at support.

Eventually: EXPLOSIVE BREAKDOWN BELOW

Why Compression is Powerful

Types of Compression

1. Ascending Triangle Compression

• Flat resistance + rising support (higher lows)
• Buyers increasingly aggressive
• Break above resistance = explosive move
• Target: Height of triangle from breakout

2. Descending Triangle Compression

• Flat support + falling resistance (lower highs)
• Sellers increasingly aggressive
• Break below support = explosive move
• Target: Height of triangle from breakout

3. Symmetrical Compression (Pennant/Wedge)

• Both converging → bilateral breakout potential
• Trade the break direction
• Often resolves in prior trend direction

4. Internal Compression (Within Range)

• Price compresses within a larger range
• Usually precedes range breakout
• Look for which side is being compressed INTO

Trading Compression

Entry Strategy:

1. Identify compression forming (3+ higher lows into resistance
   OR 3+ lower highs into support)
2. Wait for the breakout candle (strong close beyond level)
3. Enter on:
   a) The breakout candle close (aggressive)
   b) Retest of broken level (conservative)
4. Stop: Beyond the last compression point
5. Target: At least 1:1 of compression range (often 2-3×)

Anticipating Direction:

• Higher lows into resistance → likely bullish break
• Lower highs into support → likely bearish break
• Which side is absorbing? That side will win

False Break Warning:

• If breakout candle is weak (small body, long wick) → likely false
• If volume doesn't increase on break → caution
• Wait for strong close + follow-through candle

Compression + Liquidity

Compression often forms before a liquidity sweep:

1. Price compresses into equal lows (support)
2. Liquidity accumulates below equal lows
3. Price finally breaks below (sweeps liquidity)
4. Smart money fills on the sweep
5. EXPLOSIVE reversal back up through compression zone

Pro move: Wait for the sweep, THEN enter the reversal.

Identifying Quality Compression

Strong Compression:

• 5+ touches on the flat level
• Clear higher lows (bullish) or lower highs (bearish)
• Duration: 10-50 candles (not too short, not too long)
• Volume declining during compression
• Located at significant HTF level

Weak Compression (Avoid):

• Only 2-3 points
• Messy, no clear pattern
• Already compressed too long (exhaustion)
• Against higher-timeframe trend
