Not worth the money
The predictive system behind this app (or is it a person?) is simply not good enough to be worth the time or money (1 week trial, $30 per month after that). You can check its performance in the 'closed alerts' list after downloading the app (the list is correct). Although it MIGHT be that on average it generates slighty more winners than losers, many of the 'winners' are only 1-5 pips in the positive and that is IF you have time to close the position IMMEDIATELY after getting the alert telling you to do so, because most never even come near the Take Profit goal. And that's also not counting the spread. If you're lucky, it might do well for you, but during the days that I used and monitored it (ca. 30 trades), on average, I lost. All in all, you get quite a lot of daily alerts, many of which barely ever even manage to go in the green at all and the ones that do, usually end up as losers anyway, because of the spread. That's a lot of effort for only a few pips... IF you're lucky AND have the time to react immediately.
