Modifier un EA pour qu'il inverse ses trades

Bonjour à tous,
j'ai téléchargé il y a quelques semaines un EA gratuit qui fonction avec la parabole de sar.
Les résultats ne sont pas probants alors je me demandais s'il était possible de modifier le code source de façon à inverser les trades, c'est à dire que lorsque l'EA déclanche normalement un Sell celui-ci mette à la place un Buy et vice-versa ? Dans la logique, les pertes devraient se transformer en gains. Quelqu'un sait-il faire ça ? J'ai essayé mais je n'y parvient pas j'ai des erreurs dans le code que je ne parviens pas à résoudre faute de connaissance.
Merci à vous.

voici le code source non modifié :

La fonction qui passe les ordres d'achat ou de vente c'est "OrderSend".
Tu mets OP_SELL à la place de OP_BUY, et vice versa. Faut que tu changes les takeprofit et les stoploss, sinon il va te sortir un refus de lancer le trade

Bonsoir,
merci pour ta réponse, c'est ce que j'avais fais sans succès, peut-être effectivement à cause des SL et TP mais peux-tu développer ce que tu veux dire par changer les SL et TP ?

http://docs.mql4.com/trading/ordersend
Sur ce lien tu as tout les paramètres qu'il faut pour la fonction OrderSend. Dans ces paramètres tu as le stoploss et le takeprofit. Il faut que tu les modifies pour que les takeprofit et stoploss correspondent bien au OP_SELL et OP_BUY que tu as échangé.

celà reste du chinois pour moi mais merci pour ta réponse, je vais essayer de me dépatouiller.

Bonjour,
malgrés toute ma bonne volonté je n'y parviens pas, meme avec l'EA Moving Average (qui ne contient pas de stop loss ou TP), il y aurait-il une ame charitable qui accepterais de m'inverser les ordres sur l'EA moving average svp ? C'est à dire que l'EA place un sell à la place d'un buy et vice versa.
