Thanks for that. Found this: https://www.tradingview.com/support/solutions/43000669300-i-have-a-subscription-to-market-data-from-interactive-brokers-can-i-use-this-data-on-the-tradingview/

I very much doubt IB gives ASX live data for free, but it's worth checking. My impression is that IB had many issues about 10 years ago, but that it has improved to some degree in more recent times. I don't know if that matches with what you've read? I do know they have an office in Sydney that you can call.
