Today I tried to trade HSI, MHI, HHI.HK and MCH.HK from IB TWS, but got this error, Financial Instrument is not available for trading: Sanctioned: No Opening Trades In USA+ I was able to trade these in January 2021. What happened? I saw news about some talk about sanctions, but not those sanctions being enacted? Does anyone have a link to the full story? Is the sanction indefinite? Or is only InteractiveBrokers doing this?
