hi i would like to build my own bolliger band in the sperate chart, i know the formula of bollinger band as: mid band = SMA of 20 upper band = mid band + 1.96*(volatility) lower band = mid band + 1.96*(volatility) i have few issues need you to guide me how to build my own with IB, 1) i would like to set the mid band SMA 20, not with the closing price, i would like to replace with RSI value, 2) i don't know the calculation of volatility, but i would like to replace the price value to RSI value, 3) i would like this bollinger band and RSI in the same chart
hope i can get ur reply soon
thank you, derek
