Starc Bands are overlays used in conjunction with Bollinger Bands® to create trading signals. Starc bands are calculated by adding/subtracting a multiple of Average True Range (ATR) from a simple moving average. Bollinger Bands® are similar except standard deviation is used in place of ATR. The user may modify the input (close), method (SMA), periods and multipliers. This indicator’s definition is further expressed in the condensed code given in the calculation below.
How To Trade Using Starc Bands
Adjust the band widths with multiplier factors to control the quantity and quality of the trading signals. The trend is calculated from the slope of the ma. If a high goes above the bands and it is a down trend a sell signal is generated. Conversely, a buy is given if a low goes below the bands and it is in an up trend.
