Bollinger Band and Macd
If you plot the Bollinger Bands with your currency pair and the current price of the pair drops to the lower band, it could be taken as a sign of a coming positive reversal in the price. Conversely, if the current price rises to the upper band, it may be taken as a sign the pair is overbought and a fall in price is pending. [As the standard day setting for the moving average is 20 days, setting your Bollinger Bands to 25 days could aid you in counter trading.]
When multiple indicators are used at the same time and they reinforce each other, they can be used to identify high-probability opportunities.
Here we use the MACD (with the setting 12-day EMA and 26-day EMA). The MACD is a trend-following momentum indicator that searches for changes or breaks in a trend, just like the Bollinger Bands. The MACD can be used to ascertain whether the price is at a top or bottom. If the price of a currency pair falls to the lower Bollinger Band, you can take a look at the MACD to provide more proof of whether a price reversal is on the way or not. If the MACD is relatively low and starts to rise, a price reversal is more likely and you have reached a possible buying point.
You could also look at your moving averages for more proof. An EMA crossover, when the shorter (or faster) moving average crosses above the the longer (slower) moving average, provides additional comfort that a bull movement is coming.
In the contrary case, if the price of your currency pair rises to the upper Bollinger Band and the MACD is considerably high and starts to drop, a downward movement in the pair is more likely.
You should look to your Bollinger Bands before checking the MACD for confirmation of a break in trend. Vice versa the signal is not as effective because the MACD is a lagging indicator, meaning a significant move may have already occurred and you may enter your position too late. Look for breaks in trends using the Bollinger Band first, and then confirm it from the MACD.
When the market moves sideways, or non-directionally, the MACD does not give a good performance.
