Sorry, I just realize that you were just referencing my concerns about extended hours data. So basically we're talking $200/year for something that would meet my needs. A few things would need to happen before I commit to this, the first of which would be to get a TTS status!
Yes, I did and compared the data with my Webull account chart. It is incomplete and the website doesn't clarify if the paid subscription opens up all extended hours trades. I trade from Singapore so 4:00 am is 4:00 pm for me... much more manageable! I use my Webull account to exclusively trade EXT and still manage a 30+% return so it's not negligible.
That's unfortunate. I believe the free trial is already the full version so paying for subscription isn't gonna change that. You can try switching and see if the chart shows 1 second interval. If it does than you're already on the premium plan. You can always use webull between 4am-6am? Then switch to tradingview once the premarket data becomes loaded up. Whatever your decision... Best of luck to you!
