Why

TradeX-chart was created to give you the developer the freedom to choose your framework and not lock you in.

Secondly after talking to other developers, top on their wishlist for a trading chart was more direct control over it, so they could create their own custom plots. The extensive API will give you power over your chart data like you never had before. Subscribe to the internal events messaging to trigger events in your own application.
