Typically three lines are shown; a moving average and then a lower and upper band. This creates the appearance of the price moving within an envelope, and the envelope widens during times of volatility and contracts during sedate markets.

Bollinger Bands have multiple uses, including forecasting volatility, reversals, trend continuations and profit targets. The middle line is a 20 period moving average, and the outer bands are always two standard deviations away from the moving average.

As volatility increases, this makes the standard deviation larger and therefore the bands expand. When the market is quiet, the bands contract since the standard deviation gets smaller.

The actual calculations for the indicator are beyond the scope of this article, yet it is important to understand that Bollinger Bands expand and contract with volatility or lack of it, respectively. John Bollinger recommends 20 periods for the moving average, and 2 standard deviations for the outer bands.

Traders can alter these settings to suit their own strategies or market, but Bollinger did note that using less than 10 periods is not likely to work well. Bollinger made several observations about Bollinger Bands. Of those observations I find two of them the most intriguing; below I discuss these two observations as well as personal trading methods for how to utilize the observations in the real world.

A sharp price movement tends to come after the bands have tightened significantly. When Bollinger Bands tighten, it is means the price is being compressed like a spring. When trading, mark the high and low of the price range. This will likely be similar to the Bollinger Bands levels. If the price breakouts out on a 15 minute chart, the binary option trade should ideally expire within the next 15 minutes, or 3 to 4 bars after the breakout 45 to 60 minutes as this allows for a pullback and then another move in the breakout direction.

If trading an hourly chart, the binary option should expire within the next hour, or the next three to four hours. A move that originates at one band tends to go all the way to the other band. This method is useful for trading purposes.

For example, if the price bounces off the lower band even if it penetrated it and then starts moving back toward the upper band, assume that the price will move close to the upper band. If the price bounces off the upper bands and then starts to move back toward the lower band, assume the price will move close to the lower band. The price may stop just short of the band, or pierce it. What matters is that the price gets close to a band, and then starts to move back toward the other band.

If trading an all-or-nothing binary option, buy puts when the price begins to fall away from the upper band. Buy calls when the price begins to rise off the lower band. Estimate how long it will take for the price to reach the middle moving average line, and then use that estimate as your expiry.

Since the tendency is for the price to move from one outer band to the other outer band, is even more likely that the price will at least move to the moving average line after bouncing off an outer band.

I prefer using this method when the price is moving in an overall sideways direction. When a strong trend develops, for example a downtrend, it is very possible to have multiple losing trades in a row when buying calls as the price bounces off the lower band. Therefore, avoid trading against the trend.
