Closed Bars with Low < Bollinger or High > Bollinger

  A request that was addressed to ProRealTime:

  I am using a Bollinger Band indicator with SMA5 and 1,8 deviation.
  I was trying to implement a screener to show occurrencies of closed Bars with Low < Boll- or High > Boll+.
  I tried to use the automatic code builder, then adjusted it a bit, but t seems not to work as expected.
  How should it be modified to work properly?

  Suggestion for an anwser:

  p=5 //time period calculation of bollinger s=1.8 //standard deviation REM Calculate the moving average of Bollinger and the standard deviation moyenneBollinger = AVERAGE[p](CLOSE) REM Define standard deviation (can also be done using the STD fonction) IF BARINDEX >= p-1 THEN sumy2 = 0 sumy = 0 FOR i = 0 TO p-1 sumy2 = sumy2 + SQUARE(CLOSE[i]) sumy = sumy + CLOSE[i] NEXT ecartType = SQRT(sumy2 / p - SQUARE(sumy / p)) ELSE ecartType = UNDEFINED ENDIF REM Deduce Bollinger bollSup = moyenneBollinger + s * ecartType bollInf = moyenneBollinger - s * ecartType //bollMoy=(bollSup+bollInf)/2 c1 = (bollSup < high[1]) c2 = (bollInf > low[1]) criteria = close SCREENER[c1 or c2] (criteria AS "Price")

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

  p=5 //time period calculation of bollinger s=1.8 //standard deviation REM Calculate the moving average of Bollinger and the standard deviation moyenneBollinger = AVERAGE[p](CLOSE)   REM Define standard deviation (can also be done using the STD fonction)   IF BARINDEX >= p-1 THEN sumy2 = 0 sumy = 0 FOR i = 0 TO p-1 sumy2 = sumy2 + SQUARE(CLOSE[i]) sumy = sumy + CLOSE[i] NEXT   ecartType = SQRT(sumy2 / p - SQUARE(sumy / p)) ELSE   ecartType = UNDEFINED ENDIF   REM Deduce Bollinger bollSup = moyenneBollinger + s * ecartType bollInf = moyenneBollinger - s * ecartType //bollMoy=(bollSup+bollInf)/2   c1 = (bollSup < high[1]) c2 = (bollInf > low[1])   criteria = close   SCREENER[c1 or c2] (criteria AS "Price")
