Support & Resistance

Price levels where buying pressure (support) or selling pressure (resistance) historically causes price to reverse or pause.

What is Support and Resistance?

Support: A price level where buying interest is strong enough to prevent further decline. Price tends to "bounce" off support.

Resistance: A price level where selling interest is strong enough to prevent further advance. Price tends to "reject" at resistance.

Why They Work

These levels form because traders remember past prices:

  • Buyers who missed previous lows want to buy at support
  • Sellers who missed previous highs want to sell at resistance
  • Stop-losses cluster around these levels

Identifying Key Levels

Historical Highs/Lows

Previous peaks and troughs often become future S/R.

Round Numbers

Psychological levels like $100,000, $50,000 attract orders.

Moving Averages

200 SMA, 21 EMA often act as dynamic S/R.

Volume Profile

Price levels with high historical volume.

Trading S/R Levels

Bounce Strategy

  • Buy at support with stop below
  • Sell at resistance with stop above

Breakout Strategy

  • Buy when price breaks above resistance
  • Sell when price breaks below support

Role Reversal

  • Broken resistance becomes support
  • Broken support becomes resistance

Strength Indicators

Stronger levels have:

  • Multiple touches without breaking
  • High volume at the level
  • Confluence with other indicators
  • Longer timeframe significance

Common Mistakes

  1. Treating S/R as exact prices (they're zones)
  2. Ignoring context (trend direction matters)
  3. Not using stop-losses
  4. Fighting strong breakouts
  5. Over-relying on S/R alone
