Bollinger Bands Trading Strategy One should actually buy when the upper band is exceeded and short when the lower band is broken to the downside One should buy on strength as one approach the upper band only if an indicator confirms and sell on weakness as the lower band is approached, if and only if confirmed by other indicators Upper band = midline + 2 Std Dev. Lower band = midline – 2 Std. Dev. John Bollinger decided to use two Standard Deviations as the basis for counting variable-width bands, so as not to widen the dynamic channel too much and limit cases where prices may fall outside the bands. Bollinger Bands are a technical analysis tool used to analyze the price and volatility of a traded asset in order to make informed buy or sell decisions. They consist of three lines or bands — one simple moving average (SMA) line and two standard deviations of the price (upper and lower) lines. ( (Upper Band - Lower Band) / Middle Band) * 100 A Bollinger Band indicator consists of a middle band with two outer bands. The middle band is a simple moving average usually set at 20 periods. The outer bands are usually set 2 standard deviations above and below the middle band. The bands automatically widen when volatility increases and contract when volatility decreases. Theoretically when price touches upper band / lower band it reverses to average. That means upper bollinger band acts as resistance and lower band acts as support. Middle Band = 20-day simple moving average (SMA) Upper Band = 20-day SMA + (20-day standard deviation of price x 2) Lower Band = 20-day SMA - (20-day standard deviation of price x 2) Download Bollinger Band Excel Template. BOLU = MA (TP, n) + m ∗ σ [TP, n] BOLD = MA (TP, n) − m ∗ σ [TP, n] where: BOLU = Upper Bollinger Band BOLD = Lower Bollinger Band MA = Moving average TP (typical price) = (High + Low

Bollinger Bands are indicators that are plotted at standard deviation levels above, and below a simple moving average. Since standard deviation is a measure of volatility, a large standard deviation indicates a volatile market, and a smaller standard deviation indicates a calmer market. Assume a 5 bar Bollinger band with 2 Deviations, and assume the last five closes were 25.5, 26.75, 27.0, 26.5, and 27.25. Calculate the simple moving average: 25.5 + 26.75 + 27.0 + 26.5 + 27.25 = 133.0. 133.0 / 5 = 26.6. Next, for each bar, subtract 26.6 from the close and square this value: For the upper band, add the standard deviation to the moving average. For the lower band, subtract the standard deviation from the moving average. Typical values used: Short term: 10 day moving average, bands at 1.5 standard deviations. (1.5 times the standard dev. +/- the SMA) Medium term: 20 day moving average, bands at 2 standard deviations. https://www.forexboat.com/ Get Your Free Membership Now! The Bollinger Band is a volatility based indicator used in Forex trading. The tool is among the most The Bandwidth formula is: Bandwidth = (Upper Bollinger Band ® - Lower Bollinger Band®)/Middle Bollinger Band® Applying the Bollinger Bandwidth Strategy: Top Tips Bollinger Bands are a technical analysis tool used to analyze the price and volatility of a traded asset in order to make informed buy or sell decisions. They consist of three lines or bands — one simple moving average (SMA) line and two standard deviations of the price (upper and lower) lines. Bollinger Bands are displayed as three bands. The middle band is a normal moving average. In the following formula, "n" is the number of time periods in the moving average (e.g., 20 days). The upper band is the same as the middle band, but it is shifted up by the number of standard deviations (e.g., two deviations).
Also in market place there is lot of modify Bollinger Bands concept which is known as a double bollinger bands afl, bollinger band and cross over system for amibroker afl, bollinger band stop loss, bollinger bands reversal, bollinger %b afl, bb squeeze indicator afl, squeeze momentum indicator afl etc.

As you can see, the Bollinger Bands calculation using only a Simple Moving Average with 2 standard deviations. Note: Bollinger Bands® is a registered trademark of John Bollinger. SharpCharts Calculation * Middle Band = 20-day simple moving average (SMA) * Upper Band = 20-day SMA + (20-day standard deviation of price x 2) * Lower Band = 20-day SMA - (20-day standard deviation of price x 2) Standard deviation is a mathematical formula that measures volatility, showing how the stock price can vary from its true value.By measuring price volatility, Bollinger Bands® adjust themselves Bollinger Bands Trading Strategy One should actually buy when the upper band is exceeded and short when the lower band is broken to the downside One should buy on strength as one approach the upper band only if an indicator confirms and sell on weakness as the lower band is approached, if and only if confirmed by other indicators Upper band = midline + 2 Std Dev.
