When is EA operative?

Ernest Klokow 2022.10.13 08:30

I program an EA on a certain broker's MT4 and then I copy it over to another broker for live trading. If the EA already exists on the other broker I overwrite the exisiting .exe with the new version. (Parameters stay the same)

The older version of the EA on this second broker is already attached and working on several currency pairs. If I now copy the new version of the EA over the exisiting one in the MQL4/Experts folder and press "Refresh" on the Navigator will the new EA be operative or do I now have to replace the old version EA with the new version on every currency pair?

Transfer old versions of purchased EAs between platforms
So still, what is the product from the marketplace linked to?
im having this problem for my EA on mt4 Can anyone help ASAP why is this happening, cannot load 'C: Program Files (x86) MetaTrader 4 MQL4 Experts Trinsaux.ex4'

There is no .EXE.
Shutdown the terminal, then overwrite the .EX4.
Since you didn't, the parameters may now be different. Fix one, save a template, apply on other charts.

Thanks for that feedback!

Sorry! I meant .ex4 - old habit from previous programming!
