Classic Candlestick Pattern Explanation: W Bottom (Double Bottom)
The W bottom, also known as a double bottom pattern, is the most classic bottom-reversal candlestick formation at the end of a prolonged downtrend. The overall price action resembles the letter “W” and is one of the key signals for judging a trend shift from falling to rising.
Pattern Structure Characteristics:
After a sustained downtrend, the market forms two successive troughs. The prices of the two lows are basically the same and do not make a new low. The rebound high point between the two bottom lows is the key resistance level of the W bottom—the neckline.
Market Logic Behind the Pattern:
After the first low is formed following the down leg, bargain-hunting capital enters and drives a modest rebound. However, the selling pressure overhead has not been fully absorbed, so the market falls again to form the second bottom (second probe).
This second pullback cannot break below the first low. This indicates that the bearish sell-off momentum has been completely exhausted, the support below is effective, buyers’ strength gradually begins to dominate the board, and the trend-reversal signal is initially taking shape.
Core Entry Signal:
The most critical effective signal of the W bottom is a volume-backed breakout above the neckline.
After an effective breakout, the market is highly likely to pull back to the neckline to test it, thereby completing the confirmation of support. At that point, the entire double-bottom pattern is fully completed. The downtrend is officially switched to an uptrend—this is a steady, low-risk opportunity to enter.
Trading Volume Confirmation Rules (Most Important):
1. The trading volume at the second bottom must be clearly lower than the volume at the first bottom. This shows that bearish selling pressure is decreasing and the market is stabilizing as supply/positions gradually “settle.”
2. During the neckline breakout phase, volume must expand. Breakouts without volume are often false breakouts, and the pattern’s validity is significantly reduced.
Upside/Downside Potential Estimation:
The theoretical upside after the W bottom forms is roughly equal to the vertical distance from the bottom low to the neckline level. This can be used as a reference for take-profit and target projections afterward.
Invalidation Conditions:
If, during the second probing low, the price effectively breaks below the first bottom low, it means the bottom support has collapsed and bearish momentum has restarted. In that case, the W bottom pattern is immediately invalid, and it is strictly forbidden to blindly enter based on the pattern.
