Hi! I'm looking for an application, website, or some type of software where I can see live GEX levels during my trading and possibly overlay them on my TradingView chart.
I'm also looking for historical GEX levels in order to backtest a strategy I'm working on.
I prefer free software or open-source ones (of course), so if you have any recommendations or know anywhere that I can find that, that would be awesome!
Thanks in advance!
Edit: Some people are saying there is no free tool. I understand. But what tool can I use if there is no free tool? Suggestions?
