Why does ib_insync require market data subscription when standard ibapi client doesn't? #535

Hello, I am trying to replace ibapi client provided by IBKR with your ib_insync library, and similarly to #461 , #514 , #234 , #19 - ib_insync shouts at me that I have no market data permissions. What is different in ib_insync.reqHistoricalData vs ibapi.reqHistoricalData ? The standard ibapi client allows me to access historical data without additional subscription.

There's no difference.
