@Mattie, I learned something new today, did some research, here are what I found, correct me if I am wrong. First of all, the 24-trading (more specifically from 8pm to 4am next day) is a ThinkOrSwim thing, Sierra doesn't have a "thing", it just faithfully presents what ever data that exchanges offer. TOS used to be owned by TD, and recently purchased by Charles Schwab, this Web Page of Charles Schwab says, over night trading is "exclusively on thinkorswim platforms", my understanding is that transactions are among TOS accounts. This Video also mentioned the overnight liquidity is absurd, I verified by loading tick charts for SPY and QQQ on my TOS platform, there were almost no bars printed overnights, meaning, we could barely notice any difference between a TOS' tick chart and a Sierra's tick chart, either SPY or QQQ. The video also mentioned that you can only place limit overnight orders on TOS, market orders are not available. Just I thought it was only a TOS thing, I noticed SPY and QQQ have 24-hour data on Ninja too, I will have to ask them and find out why. Will get back to you Date Time Of Last Edit: 2024-06-16 17:00:40
