The idea behind Bollinger Bands is to get a sense of whether a stock’s price is high or low, relative to the market, and how much volatility is playing a part in impacting prices. This can help with making decisions about whether to buy or sell a particular stock and when it makes sense to do so.

As the bands grow and contract, it’s easy to see the volatility of the stock’s price, which informs traders as to how much movement they might expect to see in a given day. Once the indicator is set up and seemingly working well, the indicator may still have a tendency to produce false signals. During low volatility times, the bands will contract, especially if the price is moving sideways. During such times, the price may bounce off both the upper and lower band. The narrow bands are just closer to the price and thus likely to be touched.

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. It occurs when a reaction low forms close to or below the lower band.

What is average true range in stocks?

Average True Range (ATR) is the average of true ranges over the specified period. ATR measures volatility, taking into account any gaps in the price movement. Typically, the ATR calculation is based on 14 periods, which can be intraday, daily, weekly, or monthly.

The most important thing to remember is to limit trading activity during the compression phase. Usually this period is full of chop and headfakes that can frustrate traders to a point of over leveraging a position on the wrong side when the expansion phase forms. All breakouts and breakdowns look identical to wiggles, except the pullbacks are shallower as they make higher highs and higher lows on breakouts and lower highs and lower lows on breakdowns.

For instance, you can use them to gauge how likely a stock’s price trend is to continue in the near- or long-term, based on whether the movement is up or down. They can also be helpful for determining when a period of low volatility may be followed by a period of increased volatility or vice versa.

In the chart depicted below, Bollinger Bands® bracket the 20-day SMA of the stock with an upper and lower band along with the daily movements of the stock’s price. Because standard deviation is a measure of volatility, when the markets become more volatile the bands widen; during less volatile periods, the bands contract. Many traders believe the closer the prices move to the upper band, the more overbought the market, and the closer the prices move to the lower band, the more oversold the market. John Bollinger has a set of 22 rules to follow when using the bands as a trading system. The upper and lower bands are typically 2 standard deviations +/- from a 20-day simple moving average, but they can be modified.
