Post the code you are running and I'll take a look at it. (and please use the SRC button and then paste the code in)

Jose Francisco Casado Fernandez 2016.12.05 07:13 #2

It's due to the code of your EA. Regards-

The only difference with mt5 platform installation that I have done are the junction on other hard disk (not ssd) to decrease the wear.

I post the code I have used to testing with same result:

Why are you posting it again ? Is there any change ?

Pietro Caporale 2016.12.09 14:47 #7

Good question, I had not read well that this time you looked anyway.

No any change ...

I had some very challenging days.

Nguyen Danh 2019.07.26 02:01 #8

Has anyone had a solution for this, I still have this problem

Martin Botha 2019.11.07 07:26 #9

Hi Everyone.

I am experiencing the same problem. I am creating the EA with the wizard "Generate" and the only change I make is by selecting "Moving Average" as the indicator. (Note that the error persist when selecting other indicators)

Error: "2019.11.07 09:24:27.512 Core 1 tester stopped because OnInit returns non-zero code"

Martin Botha :

Hi Everyone.

I am experiencing the same problem. I am creating the EA with the wizard "Generate" and the only change I make is by selecting "Moving Average" as the indicator. (Note that the error persist when selecting other indicators)

Error: " 2019.11.07 09:24:27.512 Core 1 tester stopped because OnInit returns non-zero code "

I checked your example on

- launched a single test -> no errors

- I started testing on the history -> there are no errors.

I wonder what you are doing and on which hardware? How do you get the error? Describe your actions step by step.

Added: in case of any errors, I strongly recommend reading everything that is written in the "Journal" tab.
