Double Bollinger Bands (DBB): A Guide for Forex Traders

The Forex market is a constantly changing and dynamic place, with price movements that can be difficult to predict. However, with the right tools and strategies, traders can improve their chances of success. One of the most popular and effective tools in Forex trading is the Double Bollinger Bands (DBB). In this blog post, we will explain what the DBB is, how to construct it, and how to use it to make informed trading decisions.

What is the Double Bollinger Bands (DBB)?

The Double Bollinger Bands (DBB) is a technical indicator that is used to help traders identify potential trend changes and trade opportunities. The DBB consists of two Bollinger Bands that are placed on top of each other, with the lower band representing the lower boundary and the upper band representing the upper boundary. The bands are based on a moving average, and they expand and contract as the price of the underlying asset moves. The distance between the bands is determined by the volatility of the price action, with the bands expanding during periods of high volatility and contracting during periods of low volatility.

How to Construct the Double Bollinger Bands (DBB)

The DBB is constructed using the following steps:

1. Determine the moving average: The first step in constructing the DBB is to determine the moving average that will be used as the base for the bands. The most common moving average used is the 20-day simple moving average (SMA).
2. Calculate the standard deviation: The next step is to calculate the standard deviation of the price action over the same period as the moving average. This will be used to determine the distance between the upper and lower bands.
3. Create the upper and lower bands: Once the standard deviation has been calculated, the upper and lower bands can be created. The upper band is calculated by adding the standard deviation to the moving average, while the lower band is calculated by subtracting the standard deviation from the moving average.

Price Behavior in the Three Zones of the Double Bollinger Bands (DBB)

Once the DBB has been constructed, traders can use it to identify potential trade opportunities by examining price behavior in the three zones of the DBB. These zones are:

1. The upper band zone: This is the area above the upper band and is considered to be an overbought area. Prices in this zone are likely to fall as traders take profits.
2. The middle band zone: This is the area between the upper and lower bands and is considered to be the neutral zone. Prices in this zone are likely to be range-bound, with no clear trend in either direction.
3. The lower band zone: This is the area below the lower band and is considered to be an oversold area. Prices in this zone are likely to rise as traders look to buy on the dip.

Determining the Trend and its Direction

In order to make informed trading decisions, traders must be able to determine the trend and its direction. The DBB can be used to do this by looking at the price action in relation to the bands. If the price is above the upper band, the trend is considered to be up. If the price is below the lower band, the trend is considered to be down. If the price is between the bands, the trend is considered to be neutral.

Finding Good Entry and Exit Points

Once the trend and its direction have been determined, traders can use the DBB to find good entry and exit points. For example, if the trend is up and the price is in the lower band zone, traders can look to enter a long position as prices are likely to rise. They can use the upper band as their target, and exit the trade once the price reaches the upper band or starts to show signs of reversal.

On the other hand, if the trend is down and the price is in the upper band zone, traders can look to enter a short position as prices are likely to fall. They can use the lower band as their target, and exit the trade once the price reaches the lower band or starts to show signs of reversal.

It is important to note that the DBB should not be used in isolation, but rather in combination with other technical indicators and fundamental analysis. Traders should also have a well-defined risk management plan in place, as the Forex market can be unpredictable and volatile.

In conclusion, the Double Bollinger Bands (DBB) is a useful tool for Forex traders that can be used to identify potential trend changes and trade opportunities. By understanding the three zones of the DBB and how to determine the trend and its direction, traders can find good entry and exit points and increase their chances of success in the Forex market.
