I don't recommend this system as it is just a lagging indicator (mostly customized MAs with other two oscillators), you will get signal of trend direction on 30 minutes time frame, which most of times are late and you miss the move, or fake trend change so you end up with losses, so I couldn't find it useful for such amount of money $189. you can find many free trend indicators similar to it or even better.
Also, as for the results you see here, don't get cheated, as they are daily trades opened manually by the system owner, and most of the time we don't know why he opened the trade or closed it, it is not connected to the system, and it seems he depends on his trading experience, and trying to make customers feel that these results are directly connected to his system performance, but in reality this is not true, and whatever you do with his system, you will not get the same results or even any long term profits.
And you can follow the system creator twitter account or website and see the daily trade he opens and you will understand what I mean.
And finally, take care of his trick, as he claims that the purchase is refundable without any conditions or questions, but when you will try to refund he will come by any reason to stop that, specially he hides a piece of info stating that refund period is just 10 calendar days from purchase day, and he hides this info in the website, so many customers get tricked and when they try to refund their money he will tell them that time is passed!
Please take care, and let me know if you need any further details and advice!
