Double Bottom
The Double Bottom is the bullish counterpart of the Double Top. It forms when prices touch a support level twice with a moderate bounce in between, then break above the resistance formed by the intervening high. The pattern signals that sellers have failed twice and the trend may reverse upwards. Indian swing traders favour double bottoms after sustained corrections, especially on weekly charts of liquid stocks.
Key takeaways:
- Double Bottom has two roughly equal lows with a rally between them.
- A break above the intervening peak (the neckline) confirms the pattern.
- Volume usually decreases on the second bottom and surges on the breakout.
- Target = distance from lows to neckline, projected upward.
- Reliable after a long downtrend; less effective in ranging markets.
Anatomy of the Double Bottom
- First low: Strong selling exhausts; price prints a swing low.
- Bounce: Prices rally to an intermediate peak — this peak becomes the neckline.
- Second low: Selling resumes but stalls near the first low, forming a comparable trough.
- Breakout: Price closes above the neckline, confirming the reversal.
Confirmation rules
Wait for a clean close above the neckline before going long. A retest of the broken neckline as new support offers a higher-probability entry. Stops can be placed just below the second low.
Volume signature
Volume typically shrinks on the second bottom — indicating exhaustion of selling. A surge on the neckline breakout is essential for high-conviction trades. Breakouts on weak volume have a higher failure rate.
Measuring the target
Calculate the vertical distance from the two lows to the neckline. Add that distance to the neckline breakout price to estimate the minimum upside target. Strong patterns can extend well beyond the measured move.
Common variations
- Adam & Eve bottom: Sharp V-bottom followed by a rounded second low.
- Tri-test: Three close lows that form a “W” with a final third test before the breakout.
- Failed double bottom: Breakout fizzles and price slides below the lows — manage stops actively.
Trading double bottoms in India
Indices and large-cap stocks tend to print clean double bottoms at major support zones such as 200-day moving averages or psychological round numbers (e.g., Nifty 17,000). Combine the pattern with bullish RSI divergence and positive volume profile for higher-quality long entries. Options traders can use bull call spreads to capture the move with capped downside.
Frequently asked questions
How close in price should the two bottoms be?
Typically within 3% of each other. Wider variation weakens the pattern.
What is the best time frame?
Daily and weekly charts produce the most reliable signals.
Should I wait for a retest before entering?
It is a higher-probability entry than buying the initial breakout, but you may miss strong moves.
Can a double bottom fail?
Yes — if price breaks back below the second low, treat it as a bearish continuation and exit immediately.
