Hello,
For every indicator posted, Ninjacator has a quick video clip of each, kinda an intro of what it is.
You can get to their website and check out the indicator you have chosen to use. Not much of anything in detail really, but at least a quick and general of what the indicator is all about.
As always, just like majority of all vendors out there, they make it all look like so easy and stress-free to make tons of money using their indicators.
Just an example of what I am talking about.

Finally, as always, I am not here to judge anything. Not stating these posted indicators would bring you money nor they would make you go broke.
In the end and the reality is, trading and trading as a successful trader for that matter, is a whole lot more to it than to just simply having a bunch of indicators, strategies or bots under our belts. No matter how expensive they are.
