Hi,

I have more Zorro script, but after running 4 and more script communicate with the MT4, than MT4 terminal work like frozen ( is a very slow ).

I use this schema:


But may be is a better idea for each script create own dll plugin. ( copy and rename )



Do you have anybody experience with this?

This will make no difference. Each instance of Zorro will already have its own copy of the DLL in memory anyways.

You might have an interprocess locking problem.

How about copy MT4 to seperate folder and run second instance?
Then is the question how point some Zorro instances to one and others to the other MT4 instance running on the same VPS.

Is a problem with MT4 terminal. Is a very old SW and in the single thread. But this problem take up with version 2.xx.n. In the older version is without problem. I also trying the SET(LOCK/UNLOCK) and unaffected.

On a VPS:

1. start one MT4 terminal with zorro plugin
2. start more Zorro script / each diferent / with MT4
3. terminal MT4 - react very slow,
4. close all Zorro script except one - MT4 still not react ( I trying get terminal to front - no work )
5. close last Zorro - MT4 work without problem



maybe is a problem with grafic card on the VPS.

Run more instance MT4 is now very good, consume lots of RAM and CPU

edit:

I try with other VPS - and is better. WIth other VGA, MT4 not frozen, and react normal!
