  Salve, chiedo aiuto se possibile per la conversione dell’indicatore Fisher 9 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”)

  Per favore usa sempre il pulsante “Insert PRT code” quando inserisci il codice nei tuoi post per facilitare la lettura degli altri. Grazie 🙂

  Scusami, perché hai postato questo codice che già esiste nella libreria?

  Ciao,

  “Per favore usa sempre il pulsante “Insert PRT code” quando inserisci il codice nei tuoi post per facilitare la lettura degli altri. Grazie”

  Ok grazie e scusami.

  “perché hai postato questo codice che già esiste nella libreria?”

  Il codice presente nella libreria aveva un errore nella formula, l’ho corretto e ho inserito dei dettagli grafici per meglio intepretare il segnale. La rappresentazione ed i valori sono uguali a quelli di Tradingview.
