  Bonjour,
  Voici deux prises d’écran avec le même indicateur “ZERO LAG TRENDS SIGNALS”
  Origine tradingview et traduit sur PRT. On s’aperçoit qu’avec le code PRT on a un changement alors qu’il est inexistant sur tradingview.
  Que se passe-t-il ?
  merci

  Vous ne pouvez pas comparer les deux car ils utilisent des données différentes, regardez « bar[2] par exemple », dans PRT cette barre est complètement différente de celle de Tradingview…

  Ils utilisent la même formule « zero-lag » « (src+(src-src[lag]) » mais les données sont différentes…

  les barres des deux graphiques sont strictement identiques (timeframe H4). Ce code PRT a été traduit par ivan .

  Je parlait du bandeau rouge sur tradingview et déjà vert sur PRT.

  J’ai aussi parlé de la « bannière » et cela est dû à la différence de données.

  Si vous pensez que les données sont « strictement identiques », vous devriez y jeter un autre coup d’œil…
