Actually, Infinity Futures provides two weeks of free charting for Infinity Charts, which you can try here: Infinity Charts - Software Installation

You can follow the instructions on the page for how to register for the free charting. This charting is pretty stripped down, and if you have fairly basic needs it's a good value, most people go for the $24/month service.

This is integrated with the Infinity AT, which you can also try here: Infinity Brokerage Services
