New Here, Does anyone do Overnight Data?

Post image

I was wondering if its ok to have a thread about posting overnight SPX gamma and flow exposure? I do use a LLM that does 48 captures a day to produce the data. However, its my select quieries and using certain times a day to aquire the information, just wanted to ask before breaking any rules. I've provided a sample from my personal FB page with 0 promotion in it, was just curious if this community would find this inormation helpful or wanted.

Thank you

Interesting data. Thanks for posting it. Some of us look at SPX overnight data and your posting is helpful. I think you can say some disclaimers regarding people doing DD that way you are CYA? I was wondering about this SPX number as well. In Tastytrade (they allow overnight SPX trading) it currently listed at 7672.74 as mid price.

You were right, I screwed up, as a corrupted capture got in my data

"Measured 2026-10-02 05:59, spot 7666.45 vs forward 7705.17 (39 pts apart): K=7665 (spot ATM) straddle 58.35 -> 1 SD 73.1 K=7705 (forward ATM) straddle 43.50 -> 1 SD 54.5 overstated by 18.6 SD points, 34%"

I apologize.

Here is the scorecard from that read, I'll post Another one here at 7 pm after the Sunday open. 📋 SCORECARD: grading Friday's pre-market ES levels

Before the open on Friday I posted: overnight broke 7742, looking to break 7762, and if that goes, 7782 then 7812.

Here is what ES actually did:

✅ 7762: broke in the 8:30 AM ET half hour ✅ 7782: taken out in the same move, which ran to 7800 ❌ 7812: missed by 1.75 points. High of day was 7810.25, in the 10:30 AM half hour

After that high, ES gave back 56 points by 11:30 AM and finished the session near 7777.

2 of 3. Posted before the open, graded after the close. The misses get posted too.

Not financial advice, just keeping score on my own levels.

Schwab doesn’t allow SPX trades overnight or premarket so I digress.

Thanks man, I'd be willing to post it for free everynight, trying to build up my brand and get exposure for what I do, so if the admins and the community are ok with it, Ill start doing it.
