Double Bollinger Bands Strategy
Traders should adjust their SMA and standard deviation assumptions accordingly and monitor them. The key nuance in setting up Bollinger Bands is maintaining the optimal ratio between the period of the moving average and the number of standard deviations. If the period for some reason increases to 50 bars, you should use the ratio 2.1. If the BandWidth narrows, the trader should be prepared to see a breakout of one of the Bollinger Bands. We enter the market as soon as one of the candles closes above or below the line. The direction of the position coincides with the direction of the breakout.
One of these limitations is that Bollinger Bands are primarily reactive, not predictive. The bands will react to changes in price movements, either uptrends or downtrends, but will not predict prices. In other words, like most technical indicators, Bollinger Bands are a lagging indicator.
The mechanics of Bollinger Bands
By default, the upper and lower bands are set two standard deviations above and below the moving average.

W-Bottoms and M-Tops were part of Arthur Merrill’s work that identifies 16 patterns with a basic W-Pattern and M-Pattern, respectively. Bollinger Bands use W patterns to identify W-Bottoms when the second low is lower than the first low but holds above the lower band.
At extreme lows, a failure of RSI to reach the lower band triggers a buy signal. This is similar to double top and double bottom patterns, respectively, that can occur for the price. The narrowing of the bands indicates a decrease in volatility to a minimum. The narrowing is always followed by expansion, and expansion is always followed by narrowing.
And indeed, after a while there is a transition from a bullish trend to a bearish one. If you look closely at this formula, you will understand that if the last price is located on the upper Bollinger bands, the calculation result will be 1. If it is located on the moving average, the %b value will be 0.5. And if the price falls and stops at the lower bands, the result of the above formula will be 0. As with most other technical analysis tools, Bollinger Bands, too, come with its own set of unique advantages and disadvantages.
The look-back period for the standard deviation is the same as for the simple moving average. The outer bands are usually set 2 standard deviations above and below the middle band. In the chart, the blue middle band channel represents standard bands based on a 20-period moving average.
