Yes that is true, sadly there are a lot of people who are trying to buy signals packages and they end up losing a bunch of money because of that (a friend of mine got scammed like this)
our decision to follow the premium signal should understand the risk that they are not always right, but as long as I follow it, the profits generated are the majority and it's not a complicated issue, all signals can be useless when the market is downtrend, that's where we should take decisions, not all the signals that appear should be followed, we must have own logic in doing so, they are just a support tool.
