indicateur avec Bollinger en exponentielle

  Bonjour

  je voulais me faire un petit indicateur qui m’indique quand une bougie commence et fini en dehors des Bollinger paramétrées en exponentielle sur une période de 20. Existe t’il une fonction que je peux utiliser?

  Merci

  voila le code des bandes en exponentielle si j’ai bien compris

  p = 20 dev = 1.5 BollInf = Average[p,1](close)-dev*std[p](close) BollSup = Average[p,1](close)+dev*std[p](close)

  1 2 3 4 5

  p = 20 dev = 1.5 BollInf = Average[p,1](close)-dev*std[p](close) BollSup = Average[p,1](close)+dev*std[p](close)

  Petit Indicateur…

  Candle above/below BB

  // Calculate the Bollinger Bands with exponential moving average Period = 20 //20 periods Deviation = 2 //2x standard deviation MiddleBand = Average[Period,1](Close) BollUp = MiddleBand + Deviation * Std[Period](Close) BollDown = MiddleBand - Deviation * Std[Period](Close) // Check for conditions where candle starts or ends outside the bands CandleAboveBB = (Open > BollUp and Close > BollUp) CandleBelowBB = (Open < BollDown and Close < BollDown) // Draw signals on the chart IF CandleAboveBB THEN DrawArrowUp(BarIndex,High)Coloured("Green") EndIf If CandleBelowBB THEN DrawArrowDown(BarIndex,Low)Coloured("Red") EndIf RETURN MiddleBand,BollUp coloured("Green"),BollDown coloured("Red")

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

  // Calculate the Bollinger Bands with exponential moving average Period = 20 //20 periods Deviation = 2 //2x standard deviation MiddleBand = Average[Period,1](Close) BollUp = MiddleBand + Deviation * Std[Period](Close) BollDown = MiddleBand - Deviation * Std[Period](Close)   // Check for conditions where candle starts or ends outside the bands CandleAboveBB = (Open > BollUp and Close > BollUp) CandleBelowBB = (Open < BollDown and Close < BollDown)   // Draw signals on the chart IF CandleAboveBB THEN DrawArrowUp(BarIndex,High)Coloured("Green") EndIf   If CandleBelowBB THEN DrawArrowDown(BarIndex,Low)Coloured("Red") EndIf   RETURN MiddleBand,BollUp coloured("Green"),BollDown coloured("Red")
