Fisher indicator on positive / negative green / red histogram or colors to choose.
Variable p can be modified from properties
// variable p = 89
//Fisher indicator en histograma verde/rojo positivo/negativo o colores a elegir.
//variable p puede modificarse desde propiedades
Once period = p
Once priceSmoothing = 0.3
Once indexSmoothing = 0.3
cero = 0
lowestLow = Lowest[period](Low)
highestHigh = Highest[period](High)
periodRange = highestHigh - lowestLow
midPrice = (High + Low) / 2
priceLocation = 2.0 * ((midPrice - lowestLow) / periodRange) - 1.0
If smoothedLocation[1] then
smoothedLocation = priceSmoothing*smoothedLocation[1] + (1.0 - priceSmoothing)*priceLocation
Else
smoothedLocation = (1.0 - priceSmoothing)*priceLocation
Endif
If smoothedLocation > 0.99 then
smoothedLocation = 0.99
Elsif smoothedLocation < -0.99 then
smoothedLocation = -0.99
Endif
fishIndex = Log((1+smoothedLocation)/(1-smoothedLocation))
If smoothedFish[1] then
smoothedFish = indexSmoothing*smoothedFish[1] + (1.0 - indexSmoothing)*fishIndex
Else
smoothedFish = (1.0 - indexSmoothing)*fishIndex
Endif
Return smoothedFish as "Fisher Index", cero
