where you able to find a solution for this ? i am encountering the exact same issue ?

[lgrawet]

Yes this is still an issue also for me.

More precisely, it is happening to me if I leave binance_paper_trade as connector for backtesting but not with binance connector.

[lgrawet]

This is in fact an Hummingbot bug because the aforementioned exchange classes doesn't support the _update_trading_rules() method.

I have a similar problem with the get_trading_rules() method on binance_paper_trade called by the PositionExecutor with my own strategies.

It would be nice to fix this :-)
