I do not know the program.
Check if there is trial period available, probably not, but you can always ask.
Site looks honest about what program can do, as they do not make extraordinary claims, except for tricky name of the program, which would suggest that would give you ADVANTAGE.
But program might save you from entering volatile market, if it is true that should market trend change from uptrend to flat there will be no signals produced.
Let us know which way you decided to go.
