Details please. Tick data or EOD. How far back? How deep? Generally, i'm wary of this "cheapest data" combination. But it all depends on what you want to do with it.
You don’t need to execute there, just fetch data. The data is the same as IBKR from my testing. Although I’d recommend Tradier for the lowest fee option trading anywhere.
Check out https://ginses.com I have a tailored plan including US stocks coverage ($200). Be careful, the plan priced $500+ is for global stocks/equity markets that you might not need. I would recommend to contact them first.
