Yes. If you download historical data using your plugin, your plugin uses SymbolHist. Zorro saves the file to Asset.t6.

So basically:

If it concerns your broker and your broker plugin, it’s Symbol.

If it concerns anything else, like file names of historical data, it’s your Asset name.

This way, if you download historical data with one broker for Asset A and trade Asset A with another broker, yet the brokers have different symbols for the same Asset A, they can share the same historical data by using the same t6 data. It’s by design.

This also means your asset lists will be constructed differently for each broker.
