Does anyone know any good forex signals that are out there where you pay one payment then never pay again, monthly memberships and trials then pay after that? 
Iāve yet to come across a signal provider that offers one-time payment lifetime membership, but there are plenty that offer the others you mentioned.
Most if not all offer monthly memberships, and for trials just google something like: āforex signals trialā. From there just check them out see which ones you like.
Sorry I canāt be of more help.
I donāt like one thing with signal providers, they are just too late, there is a delay which canāt be avoided. Of course if the trade is for longer term then it is ok. But even though I do not trust signal providers:) got ripped couple of timesā¦
