Screener con indicatore personalizzato

Buongiorno,

volevo chiedere cortesemente come si può trasformare l’indicatore “Enhanced Volume Pocket Pivot” visibile in questa pagina https://www.prorealcode.com/prorealtime-indicators/enhanced-volume-pocket-pivot/  in uno screner che ricerchi i giorni in cui si verifica il volume pocket pivot.

Ho provato a richiamare l’indicatore tramite il comando CALL ma non riesco a finalizzarlo e non funziona.

Allego il codice originale.

Grazie mille

// This indicator identifies different interesting configurations
// on volumes and especially on the appearance of "pocket pivots".
// As describe by Gil Morales et Chris Kacher in their book "Trade like an O'Neil disciple" ,
// a "pocket pivot" volume is an up day volume that is greater than the highest down volume day of the last 10 down days.
//
// Also this indicator try to identify "distribution day" and can help to regnonize instutionnal selling.
// O’Neil referred to these days as " heavy volume, without further price progress higher. ".
// I use these criterias to identify them : price drop greater than 0.2 % on heavier volume than the prior day
// Clusters are more relevant than a ditribution day here and there.
// When the bar count reaches 5-7 be on guard. Note that price can continue uptrends even with an elevated distribution bar counts.
// Also closing range matters
// Distribution days are erased when price index rises 5% from a ditribution day
// or after 25 trading days have passed.
//
//
// Disclaimer : this indicator is not a buying signal, it simply gives a sense of institutional buying or selling pressure  and must imperatively be
// analyzed according to many others parameters (trend, price, stage, stock fundamentals...)
//
// Here is the meaning of the different graphical elements rendered by this indicator :
//   Green bars : 10 day pocket pivots
//   Blue bars : 5 day pocket pivots
//   Dark gray bars : dow volume days bars
//   Light gray bars : up volume days bars
//   Red bars : distribution bars
//   Orange line : average volume over the last 50 days.
//   Orange Down Arrows on average line : dry volume < 45 % of the 50 days average volume
//
//
