The main framework which supports importing candles, backtesting, optimization, the most indicators out there, extensive metrics, research and many more features worth thousands of hours invested from the free time of the main developers and many contributors, while being easy to use, is and will stay open source. See and for the longer explanation on the decision to make the live plugin paid. In short: without monetization to finance the development, this project will die like many before (for example Gekko). We believe in the principle of give and take. If everyone would live this way, everything would be balanced. In that sense, it's only fair to give back if you are able to create something profitable with the main framework. In the same sense, we give back with discounts for contributors. The pricing itself being a lifetime license seems rather fair too.
