The idea was to focus on the logic of the strategy by letting the users create rules, from the values of indicators, prices, balance sheets or other parameters and optionally compare them using operators like greater, less, equal or check for crossovers, etc.

The users can create complex strategies by chaining these rules using AND/OR operators. It's not based on charts at all at the moment, just a form, and it seems like trading view is mostly charts with custom scripts.
