I noticed one signal did not open a trade because of error #134. What is error #134? Where can I find a list of descriptions of the errors, in case I will get different errors in the future? Thank you so much.
The description of error 134 is: “Not enough money”. It means that the account does not have enough money to open a trade with the specified lot size. You can see the error codes here: https://book.mql4.com/appendix/errors
