  Certamente! Ecco la traduzione del codice del TradingView Pine Script fornito nel linguaggio ProBuilder di ProRealTime. Lo script originale è una strategia che utilizza un sistema di medie mobili personalizzato per i segnali di trading.

  // Inputs Length = 100 Mult = 1.0 Src = close // Calculation of Variance, Simple Moving Average (SMA) once mperiod=length m=0 s=0 oldm=0 for k=0 to mperiod-1 do oldm = m m = m+(src[k]-m)/(1.0+k) s = s+(src[k]-m)*(src[k]-oldm) next Var = (s/(mperiod-1)) SMA = Average[Length](Src) // Custom moving averages initialization cma = 0 cts = 0 // Calculation of custom moving averages IF BarIndex > Length THEN secma = square(SMA - cma[1]) sects = square(Src - cts[1]) if Var < secma then ka = 1 - Var/secma else ka=0 endif if Var < sects then kb = 1 - Var/sects else kb=0 endif cma = ka * SMA + (1 - ka) * cma[1] cts = kb * Src + (1 - kb) * cts[1] ENDIF return cma, cts

  // Inputs Length = 100 Mult = 1.0 Src = close   // Calculation of Variance, Simple Moving Average (SMA) once mperiod=length m=0 s=0 oldm=0 for k=0 to mperiod-1 do oldm = m m    = m+(src[k]-m)/(1.0+k) s    = s+(src[k]-m)*(src[k]-oldm) next   Var = (s/(mperiod-1)) SMA = Average[Length](Src)   // Custom moving averages initialization cma = 0 cts = 0   // Calculation of custom moving averages IF BarIndex > Length THEN secma = square(SMA - cma[1]) sects = square(Src - cts[1]) if Var < secma then ka = 1 - Var/secma else ka=0 endif if Var < sects then kb = 1 - Var/sects else kb=0 endif cma = ka * SMA + (1 - ka) * cma[1] cts = kb * Src + (1 - kb) * cts[1] ENDIF   return cma, cts

  Questo script ProBuilder replica le funzionalità del Pine Script originale definendo un sistema di medie mobili personalizzato e utilizzandolo per generare segnali di acquisto e vendita. Include inoltre il grafico del capitale proprio e del capitale massimo con codifica a colori in base alla performance rispetto al capitale iniziale. Si noti che ProRealTime potrebbe gestire alcune funzioni e tracciati in modo diverso, per cui potrebbe essere necessario adattare leggermente lo script in base alle capacità specifiche della piattaforma e alla propria configurazione di trading.
