 Another head-scratcher question: Can someone show me a method of writing a formula that uses Typ() as the DA for a 20/2 Bollinger Band for all days PRIOR to a given bar, but for that bar's BB value, the BB calc would use the Open price for DA instead??? Second attempt for my previous Q: any way to access the Interval of a chart within an indicator, to base boolean decisions (or other math) on it??? Jim Figured it out - just have to do it longhand - if anyone can come up with a faster way, esp if it avoids the expansion of the Std Dev calc, please let me know. The following function finds the 20-bar, 2-SD Upper BBand based on 19 previous Typ()'s, and the current High. It uses the current Low for the Lower BBand, and the current Open for the middle. Intended use: for backtesting, to simulate what the 20/2 BB would be using intraday "Last" value for the final daily bar, to see if an extreme-band crossover would occur when the day's value was at its extreme ... One could adapt this for many other uses ...​ ​ Bollinger Band - Last-Extreme / for 20-bar, 2-SD PSum := Ref(Sum(Typ(),19),-1); MA := (PSum+High)/20; SOS := Power(Ref(Typ(),-19)-MA,2) + Power(Ref(Typ(),-18)-MA,2) + Power(Ref(Typ(),-17)-MA,2) + Power(Ref(Typ(),-16)-MA,2) + Power(Ref(Typ(),-15)-MA,2) + Power(Ref(Typ(),-14)-MA,2) + Power(Ref(Typ(),-13)-MA,2) + Power(Ref(Typ(),-12)-MA,2) + Power(Ref(Typ(),-11)-MA,2) + Power(Ref(Typ(),-10)-MA,2) + Power(Ref(Typ(),-9)-MA,2) + Power(Ref(Typ(),-8)-MA,2) + Power(Ref(Typ(),-7)-MA,2) + Power(Ref(Typ(),-6)-MA,2) + Power(Ref(Typ(),-5)-MA,2) + Power(Ref(Typ(),-4)-MA,2) + Power(Ref(Typ(),-3)-MA,2) + Power(Ref(Typ(),-2)-MA,2) + Power(Ref(Typ(),-1)-MA,2) + Power(High-MA,2); HiSD := Sqrt(SOS/20); MA := (PSum+Low)/20; SOS := Power(Ref(Typ(),-19)-MA,2) + Power(Ref(Typ(),-18)-MA,2) + Power(Ref(Typ(),-17)-MA,2) + Power(Ref(Typ(),-16)-MA,2) + Power(Ref(Typ(),-15)-MA,2) + Power(Ref(Typ(),-14)-MA,2) + Power(Ref(Typ(),-13)-MA,2) + Power(Ref(Typ(),-12)-MA,2) + Power(Ref(Typ(),-11)-MA,2) + Power(Ref(Typ(),-10)-MA,2) + Power(Ref(Typ(),-9)-MA,2) + Power(Ref(Typ(),-8)-MA,2) + Power(Ref(Typ(),-7)-MA,2) + Power(Ref(Typ(),-6)-MA,2) + Power(Ref(Typ(),-5)-MA,2) + Power(Ref(Typ(),-4)-MA,2) + Power(Ref(Typ(),-3)-MA,2) + Power(Ref(Typ(),-2)-MA,2) + Power(Ref(Typ(),-1)-MA,2) + Power(Low-MA,2); LoSD := Sqrt(SOS/20); MA := (Psum+(O+H+L)/3)/20; MA + HiSD*2; MA; MA - LoSD*2​
