Please note that this study uses a long lookback period. On daily
charts with little history, you may need to change TimeAvRngLen
to 10 in order to have enough data for the calculation.
Range 1000 The lookback period for comparing range.
Offset 1 This is to be used if using the closing price as the method for
calculating the average. It is offset forward 1 bar so that the
current bands value is fixed on the current bar. If using the
opening value then the offset can be zero as the bands will still
have a fixed value on the current bar.
StdMult1 1.0 The first bands.
StdMult2 2.0 The second bands.
StdMult3 3.0 The third bands.
StdMult4 4.0 The fourth bands.
Extra Steps 4000 The maximum lookback period for comparing range. A number too
high may degrade performance, while a number too low will
prevent the study from being displayed. The approximate
calculation is ExtraSteps = “Number of bars per day” *
TimeAvRngLen.
Price Close The value by which the Average is calculated.
