Passing data from one MT4 client to another

Hi Rangebound!

Congratulation for your interprocess communication dll for Metatrader. According to your description the basicmsgdll.dll is limited to one client-server pair on the same machine. Could you please remove this limitation e.g.: with introducion of "connectionID" for each client-server pairs.

It would help a lot and I'm willing to pay for it. Please contact me!

Thank you!

Hi,

I just wanna ask if somebody has an DLL that allows to communicate via sockets, I tried winsock, but thehe is bug with struct2string function and I can find out whats the problem is.

Or probably better would be an DDL with function that create communication via sockets.

All what I need is that two mt4 on different communicate each other (send string on network).

Could somebody help me ?

thx

I am working on a similar platform communication protocol that is lightweight and as platform independent as possible. It is not working yet but the FF thread is here: http://www.forexfactory.com/showthread.php?t=347503

My goal is to be able to pass any sort of value (bid, ask, volume, trade command [as a string], etc.). If I get this working, I will post in this thread as well. I am going more for a .NET centralized approach whereas it looks like you are going for a terminal to terminal approach. I looked at this as well. The only issue is when you want to have more than 2 terminals. With the centralized .NET approach, I should be able to have multiple terminals mixed with MT4 and MT5.

I looked on your topic and your trying to run named pipes via DLL, I have EAs that communicate in mt4 via named pipes but only DLL that they use is kernel32.

I want to make run socket communication, bcs main disadvantage of named pipes is that they could be use only on one local pc and with TCP sockets you can communicate on network...

but I can get run this socket communication, maibe it will help to recode from MSDNA code in Delphi lazarus DLL and call functions from there.

I thing we age tryind to get same goals, bcs when it somebody will be able to create to DLL from which you use for e.g send or receive functions, you will be able to communicato 2 terminal each order, or many terminal via different port with one central aplication, which you can code in C#....

Chris,

I agree that these are very similar. The great thing about IPC is that you can redirect it to where you want. For me, I want a centralized C# application. Others may use direct MT4/5 to another MT4/5.

I am looking into some other ways to implement this, one of which does use the kernel32.dll call. The other is having my dll completely self-contained so that it is basically a drag and drop into any application (MT4/5, .NET app, etc.). The latter is more complex but the one I like the most just for it's simplicity on the users' end. The other issue I've ran into which I think I've solved, is compiling the dll so it can be used in both 32 and 64 bit environments. Several of the other articles that I've read and tried to implement wouldn't work in a 64 bit environment (MT5 by default is 64 bit when available).

p.s. I'm not following this thread post by post so if I miss something, you guys please feel free to PM me.

any update?

Hi,
there is handy and easy to use EASocket component for sending of TCP messages (all for free). Visit http://www.fxaction.net to download Expert Advisor component and small client application to see messages.

If some one wants to copy arbitrage trading, what is the best technology to create a very fast MT4 copier?
