  Hi

  I am having a problem creating a Bollinger%b for an indicator i want to use. i have the formula as listed by prorealtime %b = (close – lower Band)/(upperband – lowerband).

  he problem i am having is that he built in indicator does exactly waht i need it to do but i dont want to use the “call” function. The default has a few things in it that are not part of the listed formula. it seems to have some form of Standard Deviation as well as a selection of diferant methods.

  Does anyone have the code that will replicate the prorealtime indicator exactly.

  included a pic of the kind of thin I am looking for

  If it can be useful to you, I use this that I have written.

  //Bollinger %B lengthBol = 20 multiplier = 2 avg = average [lengthBol] (close) stDev = std [lengthBol] (close) percBolH = avg + multiplier * stDev percBolL = avg - multiplier* stDev percB = (close - percBolL) / (percBolH-percBolL)*100 overbought = 80 oversold = 20 RETURN percB as"%B", overbought, oversold

  1 2 3 4 5 6 7 8 9 10 11 12 13 14

  //Bollinger %B   lengthBol = 20 multiplier = 2 avg = average [lengthBol] (close) stDev = std [lengthBol] (close) percBolH = avg + multiplier * stDev percBolL = avg - multiplier* stDev   percB = (close - percBolL) / (percBolH-percBolL)*100 overbought = 80 oversold = 20   RETURN percB as"%B", overbought, oversold
