Slingshot-30 Min. PA System - MT4/MT5 Resources

I got this system for free via email from a guy named Martin Alexander. You can probably find him by searching for "Martin Alexander" Slingshot.

I won't post his link because I think he might be a system seller.
I checked it out and made some trades and it looked good.
