MQL4 SignalSubscriber/Unsubscriber

I am interested in subscribing to EA signals using the MT4 client. I have multiple instances of the MT4 client installed on a computer. I wish to subscribe each of the computers to an EA, for example like these: [login to view URL] [login to view URL] My problem is that when I subscribe to the signal via the website, the signal tries to attach to the incorrect client (i.e. one that already has a signal subscription), and I cannot seem to find a way around it. Hence, I am interested in the following: 1) Knowing whether it is technical possible use script to subscribe to an MT4 signal. I have been looking at the MQL4 documentation at:[login to view URL] but cannot seem to determine what constitutes a valid "signal_ID" in the url's above. Is it the number at the end of the URL in the examples above? 2) If the above is technically possible, then I would like lump sum quotes for a script that subscribes to a specific signal, in a specific client terminal. For example, the script could prompt the user with a dialog box where the URL of the signal page is located. This job description is vague because my understanding of MQL4 and signal subscriptions is limited. I would be interested to receive proposals/messages and will finalise the job description based on information received. Desired Skills MetaTrader 4 (MT4), MQL 4
