Bollinger Bands®
Bollinger Bands were created by John A. Bollinger. They compare volatility and relative price levels over a period time. The indicator consists of three bands designed to encompass the majority of a security's price action: a Moving Average in the middle, an upper band (moving average plus x standard deviations) and a lower band (moving average minus x standard deviations).
Since the bands encompass normal price behavior, it is possible to identify abnormal price levels; the bands squeeze together when volatility is low and spread 烛台Bollinger Bands apart when volatility is high.

| Simple Function Version | Top | BBTOP(d, x, z) | x =Period, d =StdDev, z =Offset |
| Bottom | BBBOT(d, x, z) | ||
| Center | AVG(Cz, x) | ||
| Width | 2 * d * 烛台Bollinger Bands STDDEV(x, z) | ||
| Simple Indicator Version | Top | BBTOPd.x.z | |
| Bottom | BBBOTd.x.z | ||
| Center | AVGCx.z | ||
| Width | 2 * d * STDDEVx.z | ||
| Other Average Types of Price | Top | tAVGCx.z + d * STDDEVx.z | x =Period, d =StdDev, 烛台Bollinger Bands z =Offset, t =AverageType |
| Bottom | tAVGCx.z - d * STDDEVx.z | ||
| Center | tAVGCx.z | ||
| Width | 2 * d * STDDEVx.z | ||
| Generalized Version | Top | tAVG(w, x) + d * SQR(ABS(SUM((w) ^ 2, x) - x * AVG(w, x) ^ 2) / x) | w 烛台Bollinger Bands =Formula, x =Period, d =StdDev, t =AverageType |
| Bottom | tAVG(w, x) - d * SQR(ABS(SUM((w) ^ 2, x) - x * AVG(w, x) ^ 2) / x) | ||
| Center | tAVG(w, x) | ||
| Width | 2 * d * SQR(ABS(SUM((w) ^ 2, x) - x * AVG(w, x) ^ 2) / x) |
Width should not be confused with the Bollinger Bandwidth indicator. The width from the table above is the actual distance between the top 烛台Bollinger Bands and bottom bands. In the Bollinger BandWidth indicator, this value is divided by the value of the centerline.
Where w is any 烛台Bollinger Bands formula which returns a numeric value.
Where x is the period which must be an an integer.
Where d is the width of the distance of the bands from the centerline in standard deviations and can be any numeric value in the function version, but must be an integer in the 烛台Bollinger Bands indicator version.
Where z is the offset. An offset of 1 is 1 bar ago.
Where t is the average type. Leave blank for simple, set to X for 烛台Bollinger Bands exponential, F for front weighted, and H 烛台Bollinger Bands for Hull.
The value of the upper Bollinger Band 20, 2.00 can be written as follows.
But you can leave out the offset setting for the current bar 烛台Bollinger Bands since it is zero.
The lower Bollinger Band just changes TOP to BOT.
