EA, OnChartEvent, HotKey scripts ?

New comment
 

I am developing an EA to trade with a small keyboard, coding its respective keys to give them specific trading functions.

I already coded SUCCESSFULLY the BUY, SELL, and CLOSE ALL hotkey scripts., 

However, I can't find the right parameters/coding functions for setting up the STOP LOSS key on a position. 

Please help? 

-

I would like for my KEY_2 to have the function of setting a stop loss to an existing, opened position (POSITION _SYMBOL), equivalent to -2.0% of my account balance whenever I press the KEY_2 , 

And I know there should be an "If" statement somewhere that determines if the Position is a BUY or SELL ; therefore, placing correctly the stop loss correctly. 


Thank you very much to whoever guides me with this part of my HotKey Trading EA.

  • If you show your attempts and describe your problem clearly, you will most probably receive an answer from the community. Use the CODE button (Alt-S) when inserting code.
  • To learn MQL programming, you can research the many available Articles on the subject, or examples in the Codebase, as well as reference the online Documentation.
  • If you do not want to learn to code, that is not a problem. You can either look at the Codebase if something free already exists, or in the Market for paid products (also sometimes free). However, recommendations or suggestions for Market products are not allowed on the forum, so you will have to do your own research.
  • Finally, you also have the option to hire a programmer in the Freelance section.

Fernando, thank you very much for your support. It's the first time I publish-post anything on forums; I would have done so correctly knowing the details you share with me. 

Indeed I am clearly learning. No coding background whatsoever. 

I will continue my research with the info you have provided. Again; thank you.
