Edit an EA

[Alexandre Valero]

Hello,

I want to change my EA. I want the take profit to be expressed as a percentage of the index used (Dax30 / Nasdaq100 / Cac40). For example, if the cac40 is at 5000, I want the ea to open a position with a take profit of 1% = 5050. If the cac is at 10000, I want the take profit to be 1% = 10100 . I thank you in advance for the time you will spend studying my request. Please excuse me for my english, this is a google translation.

You have only four choices:

1. Search for it. Do you expect us to do your research for you?

2. Beg at:

   • Coding help - MQL4 programming forum
   • Make It No Repaint Please! - MQL4 programming forum
   • MT4 to MT5 code converter - MQL5 programming forum
   • Please fix this indicator or EA - General - MQL5 programming forum - Page 193 #1027
   • Requests & Ideas (MQL5 only!) - Expert Advisors and Automated Trading - MQL5 programming forum

3. MT4: Learn to code it.
   MT5: Begin learning to code it.
   If you don't learn MQL4/5, there is no common language for us to communicate. If we tell you what you need, you can't code it. If we give you the code, you don't know how to integrate it into your code.

4. or pay (Freelance) someone to code it. Top of every page is the link Code Base.
