ProRealTime – Bollinger Band – Built In Indicator

  Hi there

  Does anyone have the code for the standard/built in Bollinger Band indicator within Prorealtime?  For some reason, it provides a significantly different reading/level to anything else I compare (compared to 3 other platforms/brokers) it to on identical settings.

  Any help would be appreciated.

  Thanks

  Andrew

  Here is the code of the Bollinger Bands:

  period = 20 dev = 2.0 data = customclose MA = average[period](data) BolUp = MA+STD[period]*dev BolDn = MA-STD[period]*dev RETURN BolUp, BolDn

  1 2 3 4 5 6 7 8

  period = 20 dev = 2.0 data = customclose MA = average[period](data) BolUp = MA+STD[period]*dev BolDn = MA-STD[period]*dev   RETURN BolUp, BolDn

  I know this is an “old” post, but I react anyway:

  Maybe the difference is in the MA. PRT uses expMovAv (exponentialAverage) and Nicolas uses SimpMovAv (Average) I think.

  @Pi

  Did you spot any difference between this code and the original Bollinger Bands of the platform?

  I confirm that BB uses SMA.

  Hi Nicolas,

  I don’t have the PRT code, but I just compared the PRT BB and your BB in one chart and saw a different outcome.

  Then I changed your BB SimpMovAv  into a expMovAv, and the outcome was the same as the PRT BB. So then I knew.

  I now made a combination indicator with BB and Keltner (both with the same SimpMovAv) so that I can easily change the periods, the BB deviation and the Keltner ATR-percentage with one action without opening the probuilder. (therefor  you have to create indicator parameters named “per” (period) “dev” (BB deviation) and “ATR” (ATR-percentage)

  // you have to create indicator parameters named "per" (period) "dev" (BB deviation) and "ATR" (ATR-percentage) period = per dev = dev data = customclose MA = average[period](data) BolUp = MA+STD[period]*dev BolDn = MA-STD[period]*dev MiddleMovingAverage=Average[per](close) UpperKchannel=MiddleMovingAverage+ATR*AverageTrueRange[per](high) LowerKchannel=MiddleMovingAverage-ATR*AverageTrueRange[per](low) RETURN bolup as "BOLsim++", ma as "BOLkeltMA", BolDn as "BOLsim--", UpperKchannel AS "KeltSim hi",LowerKchannel AS "KeltSim Lo"

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

  // you have to create indicator parameters named "per" (period) "dev" (BB deviation) and "ATR" (ATR-percentage)   period = per dev = dev data = customclose MA = average[period](data) BolUp = MA+STD[period]*dev BolDn = MA-STD[period]*dev MiddleMovingAverage=Average[per](close) UpperKchannel=MiddleMovingAverage+ATR*AverageTrueRange[per](high) LowerKchannel=MiddleMovingAverage-ATR*AverageTrueRange[per](low)       RETURN bolup as "BOLsim++", ma as "BOLkeltMA",  BolDn as "BOLsim--",     UpperKchannel AS "KeltSim hi",LowerKchannel AS "KeltSim Lo"
