I want to import stocks fundamental data (profit, assets, debt, etc...) into Zorro to use in strategies. Is it possible to do this? Everything I read about importing data concerned price and volume data only, not other type of data... Thanks.

Yes.

For backtesting, you must process the fundamental data into a dataset of your choice:

For live trading, you must use the fundamental data made available by your respective broker plugin. Or otherwise pull data from any other internet source. For example, you can use the http functions:
