Nouveau commentaire
 

Hello,

I want to use the Heikin Ashi for trailing my stop loss. That is, when i'm in bullish trend if the candle n closes below the opening of the n-2 candle i close the order. Since there is already an HA indicator that has been made can you help me reading this to use it with iCustom ?
here's the code

Bonjour. Sur la partie en français faut écrire en français 

Merci
 
Sinon pour répondre à ta question. 
Tu as 4 Buffers et tu donnes les paramètres dans l'ordre des inputs 
 
Heu... C'est une réponse en mql5, mql4 ne devrait pas être trop loin
 

Bonjour,


Je savais pas que y'avait un forum français. Il y a 4 buffers 

   SetIndexBuffer(0,ExtLowHighBuffer);
   SetIndexBuffer(1,ExtHighLowBuffer);
   SetIndexBuffer(2,ExtOpenBuffer);
   SetIndexBuffer(3,ExtCloseBuffer);

j'ai pu compléter de manière appropriée le bon nb d'arguments dans la fonction.
