Something interesting I stumbled across.
If you are using IBKR Trader Workstation, there is a new chart tool.
From what I can tell, this is Tradingview tool with all the tools available.
I haven't tested everything, but if this is true, win-win!!
I feel that Tradingview is the best charting tool. Give it a go and see what you think.
Let me know if there are any limitations.
