600

Bollinger Bands are a technical analysis tool developed by John Bollinger in the early 1980s. They are a type of price envelope that is plotted two standard deviations above and below a simple moving average of the price. The bands are typically 20 days in length, but this can be customized.

Bollinger Bands are used to identify overbought and oversold conditions, as well as to track the volatility of a market. When prices move closer to the upper band, it indicates that the market may be overbought. Conversely, the market may be oversold when prices end up moving closer to the lower or bottom band.

Bollinger Bands can also be used to identify trends. When the bands are relatively narrow, it indicates that the market is in a trend. When the bands are wide, it indicates that the market is in a period of high volatility.

Bollinger Bands are a versatile technical analysis tool that can be used to identify a variety of market conditions. They are a popular tool among traders and investors, and they can be used to supplement other technical analysis techniques.
