Hey Vladimir, you have been helping me create my EA from the very beginning and asking for nothing in return and i want to thank you from the bottom of my heart. There is this one last thing i need help with, I trade multi timeframes, M5, M15, M30, H1. Im currently running the multi timeframes on a loop, what i need is that if i have a setup in M5, i want to know that the M15 has also formed a new candle, in other words open of M5 should be equal to open of M15. I've tried a lot on how to go about this but now i need professional help

Just define the following event: a new candle was born on the M15. This automatically means: the 'M15' candlestick was born and the 'M5' candlestick was born.

You cheated a little - you didn’t write anything and you didn’t develop anything on your own: you just generated an Expert Advisor in the MQL5 Wizard. The MQL5 Wizard generates simple strategies and there is no Martingale in these strategies.

You need:

  • or master the MQL5 language on your own
  • or use the search on CodeBase
  • or create a paid job in the Freelance service

bonjour Vladimir,

je suis débutant dans le développement de robot ou l'automatisation de stratégies.

en effet, j'ai code une stratégie de trading base sur le stochastic .seulement, je voudrais, augmenter la taille de mes lots après une perte et après deux gains (profits), je ne sais vraiment pas comment insérer ce code dans mon code la source.



voici mon bot

I would like if you will allow me, to also ask if it is possible to imitate the transactions by day, and by level of profit.

how to do if so?

I edited your posts to be in English.
So, you should write in English here (it is the English language forum).
 
Sergey Golubev:
J'ai modifié vos messages pour qu'ils soient en anglais.
Donc, vous devriez écrire en anglais ici (c'est le forum en anglais).

ok, thanks for the information and your help

He has already answered you in his post. You will have to learn to code yourself or hire someone to do it for you!
