Salve a tutti, chiedo aiuto se possibile per la conversione dell’idicatore Fisher scritto con Editor Pine, riporto il codice:

////////////////////////////////////////////////////////////
// Market prices do not have a Gaussian probability density function
// as many traders think. Their probability curve is not bell-shaped.
// But trader can create a nearly Gaussian PDF for prices by normalizing
// them or creating a normalized indicator such as the relative strength
// index and applying the Fisher transform. Such a transformed output
// creates the peak swings as relatively rare events.
// Fisher transform formula is: y = 0.5 * ln ((1+x)/(1-x))
// The sharp turning points of these peak swings clearly and unambiguously
// identify price reversals in a timely manner.
////////////////////////////////////////////////////////////

Length = input(9, minval=1)
xHL2 = hl2
xMaxH = highest(xHL2, Length)
xMinL = lowest(xHL2,Length)
nValue1 = 0.33 * 2 * ((xHL2 – xMinL) / (xMaxH – xMinL) – 0.5) + 0.67 * nz(nValue1[1])
nValue2 = iff(nValue1 > .99, .999,
iff(nValue1 < -.99, -.999, nValue1))
nFish = 0.5 * log((1 + nValue2) / (1 – nValue2)) + 0.5 * nz(nFish[1])
plot(nFish, color=green, title=”Fisher”)
plot(nz(nFish[1]), color=red, title=”Trigger”)

Grazie
