I'd suggest it's a broker issue. Not all brokers allow signal subscriptions. I've not heard of a broker limiting to only signals running on their servers but I guess it's possible. Please contact your broker

Any assistance appreciated on this! When attempting to subscribe to a signal (i.e. hitting 'Subscribe' on mql5.com or through the terminal) I am first prompted to enter my mql5 password in the terminal window (i.e. where the signal is described, the charts showing the singal's performance appear, etc.). However, when I submit the password the "Do you really want to subscribe?" pop-up where I am to agree to the terms of service, etc. does not appear (as I understand it should) and the follow error appears in the Journal : "Signal - subscription/renewal prohibited" and I am not able to subscribe or otherwise proceed. My account with my broker is live, funded and otherwsie functioning fine by all indications.
A separate, but perhaps related question: is there any reason that, when logged into my brokerage account, the 'Signals' terminal window only lists signals that are hosted on my broker's servers (Oanda)? For some reason I am not able to see the full list of signals in the MT4 terminal when logged into my live trading account (and I understand as a general matter signals should work across brokers without issue).
Any insight/guidance on the above very much appreciated. Thanks in advance.
