using linux mint java 17 sudo apt install ( not on machine so can't remember how I did it) We're already making plans to leave schwab because of recent behavior. Shame really because we know Tom Sosnoff and Tony Batista personally and they created a WONDERFUL product in ThinkorSwim. The TD folks were good custodians of the TOS platform. Schwab are causing many issues but it's their product now. My wife LOVES to use a bunch of scripts we added ( thinkscript) which she uses to get trade ideas using sdmove HV analysis and trend analysis. I'll code those using python, jupyter lab, pandas and use IB api to get the data feed. Not a problem my end. Finding the IB api excellent even after we had to move off ib_insync with the death of the great ewald. I miss him.
ALSO I'm not going to spend any time fixing this. We'll just move the accounts to IB and "suggest" the rest of our chums do the same. I understand why schwab are doing what they are doing but it's not for us. Tom Perkins was our chairman and Ceo and he taught us not to get excited about this stuff, it's not personal just business. Schwab did their homework prior to the acquisition and understand the ramifications of dropping linux. It's probably not their user demographic.
