Adapter un indicateur déjà codé

[KeKhou]

Bonjour, j'ai trouvé en opensource un indicateur qui m'inetéresse, GravityCenter de Moustafa Belkhayate, mais qui est codé pour NinjaTrader, j'aimerai l'adapter pour qu'il marche sur ProRealTime mais je ne sais pas vraiment comment m'y prendre, s'il y a des programmeurs qui peuvent m'aider, je vous en serait reconnaissant.

Moi non mais il me semble que PRT proposait des robots pour faire ce genre de chose, voire l'aide de programmeurs. Saurais tu au moins le commenter ? Parce que brut de code pour quelqu'un qui n'est pas au fait du code NT c'est pas limpide.

[KeKhou]

Oui je comprend, il y a déjà quelques commentaires du créateur mais non je ne saurai pas le commenter plus que cela

[Burzum]

si ça peut aider les programmeurs

[Chouini l'ourson]

Attention, c'est un indicateur qui repeint

[KeKhou]

Oui je sais mais je pense qu'il peut être simpa j'ai très envie de le tester.

Merci Burz!

[Katana]

ça veut dire quoi "un indicateur qui repeint" ?

[Chouini l'ourson]

L'indicateur va te donner une valeur à l'instant T, mais ensuite, cette valeur va continuer à s'adapter au prix.
En gros, cet indicateur va te donner 100% de réussite si tu le backtest alors que si tu l'observe en temps réel, il ne te donnera aucun signal signal.

[Chouini l'ourson]

C'est comme si le rsi cassait à la hausse la ligne des 80, puis quelques bougies plus tard le cours chute. Dans le cas d'un indicateur qui repeint, ton rsi va se rétracter sous la ligne des 80 pour ne pas générer un faux signal, alors que toi tu l'as bien vu franchir cette ligne quelques bougies auparavant.

[Katana]

D'accord, merci Chouini
