Pour toute personne intéressée, voici un exemple de la façon de mettre les résultats de backtesting dans un indicateur. Cela calcule les mêmes valeurs que vous trouverez dans l'écran de résumé du backtester de stratégie intégré. Cela utilisera la même taille de résultat que le backtester standard, c'est-à-dire que le graphique de 5 minutes récupère environ 1 mois de données, le graphique de 1 minute récupère 1 semaine de données, etc... J'ai essayé de garder cela aussi autonome que possible, alors j'ai mis la plupart du code pour les résultats dans le bas de l'indicateur. Les résultats s'arrêtent au dernier signal commercial terminé, c'est-à-dire qu'un achat a une vente. C'est le même indicateur que j'ai publié plus tôt avec le PCT Trailing StopLoss, vous verrez donc ce code ici aussi. Comme je l'ai dit dans mon article précédent, l'indicateur n'est qu'un simple EMA pour lui donner quelque chose d'utile et je ne recommande pas d'utiliser cet indicateur sur
