Double Bottom Strategy: Catching Reversals

Overview

A double bottom is a classic reversal pattern shaped like a "W." Price falls to a low, bounces, then returns to test the same low before reversing higher. It signals that sellers have failed twice to push price lower — exhaustion is setting in. This strategy enters once the pattern confirms, capturing the turn from downtrend to uptrend.

Setup

• Instruments: stocks, forex majors, index ETFs, crypto
• Timeframe: 4H or daily (more reliable on higher timeframes)
• Indicators: horizontal support line, the "neckline," ATR(14), volume
• Market regime: at the end of a downtrend, near a significant support zone

A valid double bottom needs two lows at roughly the same price, separated by a bounce that forms the neckline (the high between the two lows).

Entry rules

1. Identify two lows at the same price level with a bounce between them
2. Draw the neckline across the bounce high
3. Wait for price to close above the neckline with rising volume
4. Enter on the next bar's open, or on the retest of the neckline from above

Stop loss

• Stop below the second bottom, or 1 × ATR(14) below the lows if they are equal
• Exit if price closes below the second bottom — the pattern has failed
• Never widen the stop hoping the pattern "still works"

Use the stop loss calculator to set the level.

Take profit

• Measure the pattern: target = neckline + (neckline − low) projected upward
• Take partial profits at the measured move target
• Trail the remainder below a swing structure or the 20 EMA

Confirm the target with the risk-reward calculator.

Risk management

• Risk 1% of account equity per double bottom
• Position size = risk amount ÷ (entry − stop). Verify with the position size calculator
• Take only one reversal trade per instrument — averaging into a third bottom is gambling
• Reduce size when the broader market trend is still down; reversal patterns fail more often against the higher-timeframe trend

When it fails

Double bottoms fail when the second low breaks lower — the sellers were not exhausted after all. The stop below the second bottom is your protection. Patterns also fail when volume does not expand on the neckline break; without buyers stepping in, the reversal has no fuel.
