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.
