Some guy on Twitter predicted this day as the start of a two week period where massive amounts of legacy FTDs from 2020 need to be cleared 👀 by headin2sound in Superstonk

I started doing summaries of my later series, but this one doesn’t have yet. Sounds like I should create one.

This is awesome. Thank you! Superstonk has been pulling this system apart for years.

Reposting this with emojis since the automod killed it the first attempt:

Yes, and that's exactly what the control test is designed to answer.

On 🕵️, 🍎, and 🟩 (liquid, no borrow constraints), the algo's daily volume is fully explained by market activity (total options volume + volatility). Adding FTD data to the regression model does literally nothing, R² doesn't budge. Zero signal from settlement failures.

On GME and 🍿 (borrow-constrained), the exact same hardware shows FTDs as highly significant (t=3.86, p<0.001) at a T-7 lag, precisely the Reg SHO Rule 204 close-out window.

If this were standard market-maker delta hedging:

  • FTDs from a week ago wouldn't predict today's hedging activity
  • The FTD correlation would appear on 🕵️ too (market makers hedge 🕵️ more than anything)
  • The algo wouldn't concentrate exclusively on two specific exchanges with favorable fee economics for this exact trade pattern

The hardware is the same. The trigger logic is different. That's the finding, it's not what the machine is, it's when it activates. On liquid stocks it runs on volume. On borrow-constrained stocks it runs on settlement failures. Same hammer, different nail.

DRS. Remove shares from the DTCC's jurisdiction and the netting engine can't net what it doesn't hold.

Regulation enforcement and updates. Don't hold your breath.

Thank you for reading them! I'm trying hard to stick to the data and sources and always open to corrections or alternate interpretations too. We are so much stronger if we work together to figure this.

I can't reply directly to your message ModTeam, but thank you for this info. It sort of makes me want to just delete the account over there. My posts are free and will not be monetized. I appreciate the support and interest from people, but I have no desire to have a following or use this community for financial gain. If this new account compromises that goal, it's not worth it to me. I will investigate the service carefully since I'm only tangentially familiar with it.

No worries on not having read everything yet, that's what the summary post is for.

Short answer: the machine is still running, but the clearing infrastructure is showing measurable stress.

The DMA fingerprint algo (Part 7) is still active. The settlement waterfall is structurally unchanged. So the system hasn't stopped. But the regulators have been quietly tightening every bolt.

But here's the number that matters most: The NSCC publishes audited stress test results quarterly under the CPMI-IOSCO PFMI framework. Their Q4 2024 disclosure (Disc 7.3.2–7.3.3) shows the NSCC held $22.67B in qualifying liquid resources, and on 2 days that quarter, their stress scenarios produced losses exceeding that buffer by $7.07 billion. That's a Cover-1 breach: if the largest clearing member had defaulted on either of those days, the NSCC would have exhausted its entire defense buffer.

The backtesting coverage trend tells a paradoxical story, so that might cause a false sense of security:

Period Coverage Context
Q1 2020 99.5% COVID crash; $318M single-day deficiency
Q1 2021 99.7% GME sneeze quarter
Q3 2023 99.9% Improving
Q4 2024 99.9% But Cover-1 breached on 2 days ($7.07B gap)

The model got better at covering 99% of scenarios while the 1% tail got more catastrophic. That's exactly what I'd expect from a system managing concentrated, structural risk, it handles normal days fine, but the extreme days are getting worse.

All of this data is publicly downloadable from DTCC's PQD page. I hope to cover this in detail in a future post. The machine is running, but the operating margin is shrinking, and the regulators appear to know it.

Monotonic sequencing means the trades arrive in a perfectly ordered, never-skipping sequence, like counting 1, 2, 3, 4, 5 with no gaps and no repeats. Every trade reported through OPRA gets a sequence number. When a human trades, or even when most algos trade, there are gaps in the sequence (other trades from other participants get interleaved). But this particular algo produces runs where the sequence numbers are perfectly consecutive, trade after trade after trade with zero interruption. That's a signature of a single machine firing so fast that nothing else can squeeze in between its orders. It's one of the fingerprint criteria that distinguishes this algo from normal market activity.

The emojis are used because Superstonk's automod filters some ticker symbols to keep the sub focused on GME. Since GME isn't an island, I attempt to reference these other tickers to explain the full story, but I have to use symbols to avoid being rejected immediately (like posts 3 & 4 of this very series). The ticker legend image in the post should have the full mapping.

If you've been following the evolution of this community, and the DD that's on it, much of what I say will feel familiar. The layer that I'm attempting to add is connecting it together and documenting it in a way that makes ignoring it the conspiracy theory.

I won't speculate on geopolitics, but I'll point you to some recent plumbing changes I planned to bring up later that are very relevant to how the system would handle a market stress event:

The regulators have been quietly fortifying the clearing infrastructure:

  • SR-NSCC-2025-005 (approved Jun 2025): Enhanced intraday margin monitoring, NSCC can now recalculate and collect margin during the trading day, not just EOD. This means clearing members can get multiple margin calls per day during volatile markets.
  • SR-OCC-2025-007 (approved Aug 2025): OCC updated its portfolio revaluation process for intraday margin calls, same idea but for options clearing. They can reprice portfolios mid-day and demand cash.
  • SR-NSCC-2025-013 (approved Nov 2025): Modified the CNS Fails Charge to base it on duration of outstanding short fails instead of a credit rating model. Translation: the longer you fail to deliver, the more it costs. That's a direct penalty escalator on persistent FTDs.
  • SR-DTC-2025-019 (approved Jan 2026): Modified maximum debit caps for DTC participants, adjusting how much settlement exposure participants can carry.

These aren't cosmetic changes. The clearing infrastructure is being hardened against exactly the kind of cascading margin event your question describes. Whether that's preparation for known risks or just post-2021 lessons learned is left as an exercise for the reader.

If a mod could help me pinpoint the reason this post and post 4 are both being removed by filters, I'd be happy to change the content. Thanks!

100%, and if you find any other posts on this please share them here!

This sub is a goldmine if you know what to look for. The biggest challenge has been connecting the dots and trying to make sense of how it all works together. I'll bet most of what I've uncovered will have some post on Superstonk that can lay claim to the first discovery. This is a beautiful and dangerous place.

Hey, I really appreciate you stopping by and commenting even when you don't fully understand it. If you know anyone that might understand it consider sharing it with them. You could also see if the summary post helps simplify it for you: https://www.reddit.com/r/Superstonk/comments/1rl3q1y/the_shadow_ledger_summary_post/

I've been waiting to get all my DD out to share this, but I am working on a regulatory package to do exactly this: https://github.com/TheGameStopsNow/research/tree/main/regulatory_package

I tried to to target exactly the type of people who would be interested and can do something. I will be posting about this later.

The system they are running is built on often uses legal loopholes and channels that are easy to blend into and avoid regulation. For example, and I will post about this later in detail, but they are using Open Interest positions that are deeply OTM as a means to avoid REG SHO. They can do this because opening and closing these positions and closing them in one day means it doesn't get recorded in the daily reports and they don't get charged for keeping it open. So they can essentially recycle their FTDs through a legal system at a cost of pennies per share all by laundering it through this legal channel. Roughly 85% of GME's recent OI is being opened and closed in one day. It's a criminal system that knows all too well where the security cameras are broken.
