Simple real candle body outside Bollinger Band screener please?

  Hello all, would any of you be so generous to help me code a screener that detects when the real body (high-low) of the current candle is outside of the Bollinger Bands with user-defined Bollinger Band length and Standard Deviation?  Thank you so much 🙂

  Oh also, my (high-low) statement does not mean high minus low. I meant basically the high and low of the candle (real body) are outside of the bollinger bands(either above or below). Thank you 🙂

  Please find below the code that detects whenever the High and Low of the current candlesticks is above the upper Bollinger Band or below the lower Bollinger Band.

  Parameters of the Bollinger Bands can be changed at will in the code (period of the moving average, applied price and deviation coefficient of the bands).

  Example attached.

  // --- Bollinger Bands parameters period = 20 data = close dev = 2 // --- MA = average[period](data) BolUp = MA+STD[period]*dev BolDn = MA-STD[period]*dev condition = (high>BolUp and low>Bolup) or (high<BolDn and low<BolDn) SCREENER [condition]

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

  // --- Bollinger Bands parameters period = 20 data = close dev = 2 // ---   MA = average[period](data) BolUp = MA+STD[period]*dev BolDn = MA-STD[period]*dev   condition = (high>BolUp and low>Bolup) or (high<BolDn and low<BolDn)   SCREENER [condition]

  Let us know if it’s working properly on your side.

  Thank you so much Nicolas, it works perfectly when I run the scan! I have one more question 🙂 How do I make the Bollinger Band EMA-based, instead of SMA? Thanks again Sir!

  Just replace the word ‘average’  by ‘exponentialaverage’ and you’ll get a quicker and more reactive Bollinger bands 🙂
