I was able to subscribe to one provider, (dont know how) but when i try to subsc to any other i get the massage There are a subscription to specified trading account and period exists.
What do I do wrong
pls help :)
I had the same issue, check your subscriptions / signals.
If you have one already subscribed to, or even disabled using that MT4 provider Account, it wont allow you to add another.
I always thought could add more than 1.
Please refer to Rules of Using the Signals Service, IV.7:
One trading account can be subscribed to one Signal only.
