They will charge the money at some stage for providing signals ?
If you are in trading, your focus should be to get Technical analysis knowledge and do TA yourself. If you are looking to find signals from different groups, you cannot succeed in the long run.
No way to pay these people knowing that signals are not accurate but if you are new to trading, that could be brought some interest, and after make payment, they are gone. That is a kind of stupid idea and that supposed to stop thinking that someone or a group like the signal group could help you to make rich because in the first if they know the market trend that might they use it by themselves.
You are right, instead of relying on these people and pay them for nothing, better to make our own decisions based on the market chart. We have to use trading tools to make good TA, though.
