What does it really cost to use SpiffyCharts?

Nothing at all.

SpiffyCharts is free. We do get a small royalty on the amount you pay one of our licensed data vendors and that brings us a small amount. (The big guys get this too.) But it costs you nothing

You can also access several free data sources and we'll help you with other free sources you may find, as long as you let us know what they are.

Many people buy expensive trading software and never use it. With SpiffyCharts you can't lose.
