Bollinger Bands Contracting

(Arthur Merrill suggested multiply and dividing by one plus the desired percentage.) When I started using trading bands percentage bands were the most popular bands by far. Along the way we got another fine example of envelopes, Donchian bands, which consist of the highest high and lowest low of the immediately prior n-days. Over the years there have been many variations on those ideas, some of which are still in use. Today the most popular approaches to trading bands are Donchian, Keltner, Percentage and, of course, Bollinger Bands. Double tops and double bottoms are essential technical analysis patterns used by traders.

A double top has an M shape and signals a bearish price movement. A double bottom has a W shape and indicates a bullish reversal in trend. Bollinger Bands are a relatively simple trading tool and are incredibly popular with professional as well as at-home traders. However, using only the bands to trade is a risky strategy since the indicator focuses on price and volatility while ignoring various other relevant information.

Upper resistance and lower support lines are first drawn and then extrapolated to form channels within which the trader expects prices to be contained. As long as prices do not move out of this channel, the trader can be reasonably confident that prices are moving as expected. On their own, traders predict the price and create a vision about the upcoming trend through deep market analysis. The tool solely doesn’t allow the trader to predict the prices. Bollinger bands, over time, have become the most used technique among traders.

The bands give no signs of when the change may take place or in which direction the price might move. According to Bollinger, it is necessary to look to other indicators to determine breakout direction. He suggests using the relative strength index along with one or two volume-based indicators such as the intraday intensity index or the accumulation/distribution index.

As the pressure builds, there can be a sudden burst of https://forexarena.net/ action which can be either higher or lower.

Exponential Bollinger Bands eliminate sudden changes in the width of the bands caused by large price changes exiting the back of the calculation window.
