This is just a generic question. Using the same algorithm on two different MT4 platforms sometimes produces two different results. One platform performs as coded by the algorithm, while the other platform does not execute the algorithm correctly and results in a margin call. Is there anything that can be done about inconsistent performances of the MT4 platform? Are there any other platforms on the market that are adaptive to a C++ algorithm that produces more predictable results for expert advisors?
Are you using different brokers for the two different platforms?
No, the MT4 platforms are all from the same broker, using the same currency, same time frame, same algorithm, with the same parameters. I have 16GB of RAM and usually run over 10 MT4s at the same time to expedite forward tests with no problems. I believe that it was either a glitch in the broker’s data feed or just that one MT4 platform had a glitch. Anyways, thank you for your consideration.
That’s so weird. That shouldn’t happen. Alright, hope you figure it out!
Were you testing on demo accounts? Maybe you should bring that up with the broker…
That sounds scary! Any update on what your broker said about the issue? That’s real money on the line!
What does the error log say? Of course you will get different results if one had an error and the the other didn’t.
I know it shouldn’t happen, that’s why I was so surprised in the different results. Thank God they were only demo accounts. I am not going to waste time telling the broker about it. I don’t think they would have an answer, but if real money was on the line, of course I would be giving them a call! 
I have opened up a new demo account on that specific MT4 using the same algorithm with no problems for the last two weeks, so it must have just been a fluke. The strange thing is there is absolutely no trace of any of those transactions on the logs for that time period on that day. That’s weird!
Thanks everybody for the contribution.
