As early as in 1960, Wilfrid Ledoux used monthly highs and lows of the Dow Jones Industrial Average to predict long-term market movement. After that, the history of trading bands got lost in time, until it was resurrected by Hurst.

To understand the Bollinger band, you should know the basics of technical analysis so that you can interpret the results from the chart. As the name suggests, the Bollinger band consists of three bands named upper, lower, and middle bands. Bollinger band comprises the volatility indicator. To measure volatility we use standard deviation therefore Bollinger Bands are price envelopes drawn at a standard deviation level above and below the price’s simple moving average. In the Bollinger band, we use 2x times of standard deviation which gives approximately 95% accurate results. The line above the SMA is denoted as upper Bollinger line and the line below as lower Bollinger band.
For instance, if prices pull back but stay within the middle band and again move forward to the upper band, it discloses lots of strength in the stock. In short, the upper band is deemed as the profit target if the price drops below to the lower band and suddenly glides up and crosses the moving average. During an uptrend, traders tend to sell their stocks before the reversal occurs.

You buy when stock prices are closer to the lower band and forming a W pattern in the lower band.
Bollinger bands, over time, have become the most used technique among traders. It provides them an in-depth overview of the trend.

In simple words- during a strong downtrend, the prices are likely to stay constant alongside the lower band. That’s why technical traders pay special attention to the uptrend and constantly monitor its behavior to disclose the varying situations of weakness and strength of the stock.

For different securities, different variable settings can be chosen. Typically traders use 20-day simple moving average with a standard deviation of 2. Some traders may use exponential moving average too. A strong trend continuation is signaled if the price falls below or breaks above the moving average band with strong volume and continues to move in the same direction.
This strategy uses the RSI indicator together with the Bollinger Bands to sell when the price is above the upper Bollinger Band . This simple strategy only triggers when both the RSI and the Bollinger Band indicators are at the same time in a overbought or oversold https://1investing.in/ condition. In such situations, traders also observe the signs of ‘downtrend strength,’ especially when the price pullbacks or stays below the middle band. However, it can also indicate the reversing of the trend if the prices break above the upper band.
