Error 146 ("Trade context busy") is due to Broker Server Side or MT4 Client Side?

[shanmugapradeep]

Hello,

I am using an EA attached to 4 currency pairs in one MT4 client. I frequently encounter an error "Trade context busy." My question is, is this error due to my computer hardware resource issue (RAM/CPU), Metatrader 4 application-related issue, or Forex broker server-side issue?

If this is a Metatrader 4 client-side issue, and I open 4 MT4 applications on my computer and run 1 pair in each for the same trading account, will this issue be fixed?

Thank you.

Switching to multiple instances of the MT4 client should help with the "Trade context busy" error because, it's a client-side issue. It's also good idea to implement some code in your EAs to handle the busy context situations.

MT5 supports up to 8 trade contexts, so it will be much harder to make them all "busy".

I saw this on Article : https://www.mql5.com/en/articles/1412

Is this mean, Both MT4 & MT5 have same 8 Trade Context?

Yes, you are right. It looks like MT4 has 8 trade contexts too since Build 600.

I asked same question in MQL5 forum to be clear and it super confusing now.




This person says, MT4 has only 1 trade contexts and comments are not correct.
