I built something similar for my own personal use, so it's very interesting to see something similar polished for mass consumption.

The only thing I'm confused about is what you get in the Pro version..

"3 Months of Unlimited Access to Every Area of QuantBlocks"

How is the user supposed to know what "every area" is? How could anyone expect to know what they get with a subscription? Most importantly, how could they know if a particular symbol would be available in the pro version, what about futures, forex, etc?
