What is the Bollinger and MACD Combination?
As the title suggests, traders can make use of Bollinger Bands® in conjunction with MACD to support trade set ups. Bollinger Bands® allow traders to view the cyclical nature of volatility while the MACD is an effective trend-following, momentum indicator.
Using these two indicators together can assist traders when making higher probability trades as they can gauge the direction and strength of an existing trend, along with volatility. As a result, traders can use the MACD to assess if a trend is picking up in momentum or slowing down and setting up for a possible breakout; while the Bollinger Band® can be used as an entry trigger and subsequent confirmation of a trade.
How to Use Bollinger Bands® and MACD to Trade Forex
Traders can trade with Bollinger Bands® and MACD in a number of different ways but two of the most common ways to trade with these two indicators involve breakouts and trend trading.
Bollinger Band® Breakout Strategy using Bollinger Bands® and MACD
Traders looking to trade Bollinger Band® breakouts should consider the following steps:
- Identify a trending market using the MACD
- Look for divergence in the histograms of the MACD (signalling potential breakout)
- Look for entry on a break of the 20 moving average or trendline
- Look for confirmation of a breakout via a breach of the Bollinger Band®, along with increased volatility (Bollinger Bands® expanding) and increasing momentum (longer histograms)
In the GBP/NZD chart below, it is clear to see a strong downtrend where price starts to trade within a descending channel. Traders can trade the breakout by looking for slowing downward momentum (divergence in the MACD histograms).
A break of the 20 period Moving Average (centre line within the Bollinger Bands®), after witnessing bullish divergence, provides the signal to enter the long trade. The dotted line on the upper side of the channel represents trendline resistance and coincides with the 20 MA of the Bollinger band® when price breaks through it. A break of these two lines confirms that this is a significant level, further reinforcing the bullish bias.
The MACD indicator supports the bullish trade as the MACD line has crossed the signal line and continues to move above the signal line, showing strong upward momentum. The Bollinger Band® then confirms the move to the upside as price begins to “walk the band” on increased volatility (expansion of the band).
Stops can be placed below the lower Bollinger Band® or at the low of the descending channel. Targets can be placed at a previous high or significant level of resistance – while maintaining a positive risk to reward ratio. Since there is a possibility that the breakout trade turns into a trend reversal, traders should consider multiple target levels and manually move stops up or utilize a trailing stop.
Trend Trading using Bollinger Bands® and MACD
The Bollinger Band®, MACD combination can also be used in trending markets via the following process:
- Identify the trend using MACD
- Use bounces off the 20 MA as potential entry points (in line with the trend)
- Look to the MACD for confirmation of continuing momentum
- Use the lower (higher) band as a stop loss in an uptrend (downtrend).
The EUR/USD chart below depicts the Bollinger and MACD trend trading strategy. The MACD confirms the uptrend with MACD line above the signal line and both lines are above the zero mark. This sets the filter that traders should only be looking to enter long trades.
After the initial spike in momentum to the upside, momentum slows down and although the MACD line crosses below the signal line, these moves are on low volume and result in short term consolidation rather than a move against the current trend. The uptrend is further reinforced by the fact that price bounces off the 20 MA and continues making higher highs and higher lows.
Traders can look to enter long trades in accordance with the Bollinger Band® Squeeze (green arrows). Long traders can either choose to exit the trade as price drops to the 20 MA or can look for a breach of the lower Bollinger Band® as the exit signal.
Traders can make use of a trailing stop or stops can be manually moved along the lower Bollinger Band® as price rises. Targets can be set at significant levels of support and resistance while maintaining adequate risk management.
Advantages and Limitations of the Bollinger Bands® and MACD System
- Bollinger Bands® can be applied to any asset, across any timeframe and the same goes for MACD.
- Bollinger Bands® naturally provide stop loss levels that coincide with the lower band for long trades and the upper band for short trades.
- Traders can determine the trend and volatility of any market at a glance.
- The combination of the Bollinger Band® and MACD is not suitable for novice traders. Those that are new to FX trading will require in-depth knowledge of both Bollinger Bands® and the MACD.
- Bollinger Bands® are known to work best in ranging markets while the MACD is a trend following momentum indicator. If these are applied incorrectly, traders can receive mixed signals.
