It is so named because the pattern is in the form of English alphabet 'W', with one swing top and two swing bottoms. Hence the name Double Bottom Chart Pattern.


Trend is your friend. Dance with the friend. Tune to the trend.


How Double Bottom Chart Patterns are formed?

There are two great forces which move the price up and down. They are demand and supply. Double Bottom is the result of increase in demand over supply for the stock.

These are pressure areas in a downtrend. These are major target areas or major support areas where most traders wish to buy the stock. Here downtrend changes to uptrend.

In a downtrend the price keep making lower low swing highs and lower low swing lows. As the target area or the support area is approached there is increased buying.  As the demand increases the price rises up forming a swing low. This swing low forms the first swing bottom of double bottom chart pattern formation.

Because of increase in demand over supply for the stock, the price rises. When buying is exhausted, selling continues because it is a better price to sell in view of previous price fall. So there is an increase in the supply for the stock and the price falls. This price fall creates the swing top of this pattern.

Although many traders are selling and the price is falling, it is not backed by smart money. Major funds are not selling. Instead they are interested in buying at this level. This time the price does not fall much below the previous swing low. It does not make a lower swing low. Rather it just falls to the level of previous swing low which is the major support level.

Here the demand again increases and the price swings up forming the second swing bottom of this double bottom chart pattern. A trend line connecting the lowest points of these swing bottoms and extended to right forms the support line for this pattern.

Between these two swing bottoms there is a swing top. A horizontal trend line drawn at the highest point of this swing top forms the resistance line for this pattern.

What is the significance of Double Bottom Chart Pattern?

Pattern trading is one of the strategies of making money in stock trading. Among the chart patterns reverse double bottom chart pattern formation gives us the opportunity to cover our short position and enter a long trade. These trades will have high rate of success.

What is invisibly going on in the market is very well expressed on the visible chart. The first bottom is lower low swing low with lower low swing highs. This is in tune with a downtrend. But unusual increase in volume at this level should rise suspicion of entry of bulls to accumulate stock. It is easy to accumulate great quantity of stock in a bearish trend.

The failure of second swing bottom to form lower low swing low at the level of the previous support, tells us that the down fall has arrested. If the support is strong enough to stop the further fall of the price, it is an indication that bulls are active behind the screen. If the price takes support, it should alert the formation of two bottoms.

Next when all the sellers are exhausted, the price rises and breakout above the resistance trend line of this pattern. Here the price crosses above the previous swing high and makes first higher high. Now an uptrend begins. By definition uptrend is marked by higher high swing highs and higher high swing lows.

The moment you see a stock making a double bottoms chart pattern cover all your short position and  get ready to go long above the resistance line drawn above the high of the central swing high. A close above the resistance trend line is a buy signal to go long. Protect this long trade by placing a stop loss sell order below the support trend line of the double bottom pattern.

Once the price breaks out above the resistance line, many a time it pulls back to test the resistance turned support line. Those stocks which does not pullback after a breakout do much better than those which do pull back. Stocks which breakout with heavy volume perform better than those which breakout with low volume.

If the price pulls back and rises, move the stop loss sell order to just below the swing low formed when the price rises after pull back.

The minimum target for this long trade is equal to the range of the pattern. That is the height from the support line of the pattern to the resistance line of the pattern, applied above the resistance line from the break out point. Though this is the minimum target, many times the reward will be many times this which increases the risk to reward ratio.

The two swing bottoms need not be exactly at the same level. A difference of up to three percent, is considered as acceptable.
