Can't Load libzmq.dll in Backtester #19

Closed daniiiboy closed 5 years ago

daniiiboy commented 6 years ago

Hello Dingmaotu,

I am very new zmq, so please excuse me for this naive question.

I was able to properly install mql-zmq library following your instructions. I've put MT5 .DLLs into the Libraries folder and have enabled DLL imports on the MT5 terminal.

To begin I've written an EA that just pushes the current price every 2 seconds to the socket and a python program that listens to the socket. I was able to successfully run it on the MT5 terminal.

The issue I have encountered is when I load this simple EA into the Strategy Tester. It seems that that the tester is not able to load the libzmq.dll. See the error log bellow.

Do you know what the issue might be?

Thank you for any help :)

I also have a problem. When I compile my EA, it gives me a lot of undefined identifier. I am not sure why ?

Are you sure, that you have installed the C++ Runtime?

Hi, I had the issue of not finding the "libzmq.dll" while using the Strategy Tester. I solved it by manually copying the libzmq.dll and (libsodium.dll not sure this is needed) into the tester agent directory. I've had this problem with other unrelated DLL's in the past.

User/AppData\Roaming\MetaQuotes\Tester\D0E8209F77C8CF37AD8BF550E51FF075\Agent-127.0.0.1-3000\MQL5\Libraries

The Strategy Tester uses it own version of DLL's.
