I have a question for OP, since signals are good and you are making too much money then why are you wondering to sell that only for $50? You may become a multi-millionaire by trading with them. Then you shouldn't seek for $50 only. I have seen a few groups that are providing signals. To be honest it's not only just a waste of time but also a waste of money. Signal providers just making money themselves.
Those who want to buy signals just keep in mind, most signals just worst. If you gain in a signal then you will be a loser in other signals. It's better to learn yourself how to trade. Don't believe others with your funds.
