Some methodologies
Defined-risk options strategies on SPX and index products, driven by dealer positioning and regime. These systems carry strong Calmar and Sortino ratios across forward testing and live management.
Tick-level ingestion and per-minute aggregation of gamma / delta / vega exposure, charm, skew, max-pain and net-premium drift across the full 0DTE SPX chain, VIX and 250+ concurrent instruments.
Local LLM agents that learn the way I trade — from my notes, daily write-ups and past sessions — through a pgvector memory layer, pre-warmed with dense structural summaries instead of raw ticks.
A strategy registry with walk-forward validation and prop-firm drawdown/survival modeling, with reproducible result caching for honest, comparable evaluation.
What I'm currently building
Today I rotate one-shot calls across commercial APIs — Claude (the most capable), plus Gemini, Mistral and others — feeding each a tightly compressed market summary, because tick-level data won't fit and the plan caps run out mid-week. Moving to a self-hosted model removes the cap and lets me benchmark what actually matters for trading:
Time-to-first-token and generation latency low enough to fit inside scalping execution windows.
Sustained, minute-by-minute context injection through the session without thermal or VRAM bottlenecks.
Rapidly experimenting to learn which real-time signals carry edge — and which are noise — across high volumes of structured market data.
Decision speed fast enough for the model to react inside scalping windows — quicker than manual execution of the same methodology.
The longer-term goal is a refined local model with durable long-term memory — warmed from summary profiles and continuously taught my methodology — running at high throughput on dedicated hardware.
Selected work
A real-time SPX options analytics and automated-reporting platform: per-minute dealer-exposure snapshots, filtered net-premium drift, regime detection, and gated end-of-day / pre-open / intraday report generation — surfaced through a React charting portal, with verification gates on every published figure.
Multi-agent orchestration over a knowledge base of thousands of embedded research chunks with structured tool use. It learns from my daily write-ups and past sessions via pgvector — and is being moved off API caps onto self-hosted hardware at near-zero marginal cost per token.
Backtesting, a strategy registry and signal research (dealer-positioning, regime and ML families) with prop-firm survival simulation and reproducible, cached result sets for comparable evaluation.

2026-08-11 · Tuesday
SPX gapped up 14.4 points to an official open of 7,767.51 and never traded higher — the opening print was the session high, and what followed was a six-and-a-half-hour bleed: 7,763.37 at 10:00, 7,745.82 at noon, 7,733.29 at 13:00, into a low of 7,717.25 at 14:29, 50.3 points below the open, before closing 7,728.20 (−0.32%), eleven points off the low but 24.9 below Monday's 7,753.11; the afternoon was different from the morning for a structural reason, not a sentiment one, because through 11:00 the near-spot ±40pt book was a damping configuration — gamma +233.7 $M/$1, delta exposure +5.85Bn at 10:30 — and the tape behaved accordingly, drifting rather than trending, before both measures eroded: near-spot delta exposure crossed durably negative at 12:19, gamma followed at 12:41 after a 11:19–12:41 chop band, and by 14:30 the pair had reached −1,066.8 $M/$1 and −25.3Bn, the most destabilised minute of the session; that is a regime change rather than an exhaustion flicker, since the exhaustion signature requires both to drain at the extreme and then re-inflate as price leaves it, and here both went and stayed destabilised straight through 7,717 — the level broke because the book amplified it, and 236 of the 389 RTH minutes closed with negative near-spot gamma, every one of them after 11:19; the forward 8/12 book carries NET_NEGATIVE near-spot gamma at −23.19 $M/$1 with the put shelf 7,700 sitting 28 points below spot against a call wall 7,810 fully 82 points above, an asymmetry that matters more than the sign, while VIX closed 15.29 down 0.84% with no fear bid at all and HV30 of 9.03% against IV30 15.06% left the .15-delta condor quoting 19% of width — not enough, and no clean setup
2026-08-10 · Monday
SPX opened 7,751.74, six points under Friday's close, and never traded more than 16.1 points above it or 14.5 below — the high arrived early at 7,773.76 at 10:49 ET, stopping 1.24 points beneath the 7,775 call wall, the heaviest positive-gamma strike on the forward book, and turning without ever trading it; the session then leaked through a 12:32 consolidation break into the low of the day at 7,743.11 at 12:44, which is the one piece of genuine structure in an otherwise quiet tape, near-spot gamma having drained from +$131.8M at 12:36, crossed negative at 12:42 and troughed at −$92.1M at the exact low minute while the near-spot positive-delta magnitude supporting the level fell from $6.59B to $3.51B, both re-inflating within three minutes to +$234.0M and $5.34B as price left the low behind; the afternoon drifted back to unchanged and closed 7,753.11 (−0.06%), a full range of 30.65 points and the tightest of the run, against a ±32.3 expected move priced for the next session — the whole day spent going almost exactly one session's worth of movement nowhere; the forward 8/11 book is a 7,715–7,775 pin corridor carrying +10.23 $M/$1 of near-spot gamma with the close mid-band, and the heaviest delta strike on the board, 7,700 at +987.8 $M/$1 and nearly half the entire near-spot sum, sits 53 points below the close outside the corridor rather than inside it, with VIX closing 15.46 (+0.4%) and IV30 at 15.0% still well above the 9.03% the tape actually delivered
2026-08-07 · Friday
SPX gapped 25.2 points above Thursday's 7,709.96 close and never traded back to it — the 10:12 ET low of 7,719.19 still sat 9.2 points clear — running to 7,763.08 at 11:33 before a three-hour fade into 7,734.39 at 14:46, where near-spot gamma flickered to −$25.2M for a single minute, the only negative print of the session, while delta drained $10.8B to $6.0B in the same minute and both re-inflated to +$379M and $13.1B by 14:51 as price left the level; the structural story was the migration, with the largest positive-delta strike walking 145 points up the ladder from 7,600 at midday to 7,745 by 15:55, relocating the long-delta base from far under the tape to directly beneath it, and the session closing 7,757.64 (+0.62%) five points under its high; the forward 8/10 book is a 7,720–7,795 corridor with the close mid-band and 7,750 carrying a third of near-spot gamma, but the levels flagged as the put shelf, 7,650 and 7,675, both carry negative gamma — support below the corridor by position, not by mechanism — with VIX closing 14.90 (−2.6%)
2026-08-06 · Thursday
SPX opened on Wednesday's 7,723.55 close, pushed to a 7,742.85 high at 10:20 ET — the whole of the session's upside — and spent 76% of the day beneath the prior close, printing above it for the last time at 11:16; the 7,700 strike flipped from +$610M of delta at 11:15 to −$483M by 11:20 and deepened to −$2,487M by 15:45, gamma turned negative at 11:52, price tagged 7,698.15 at 12:16 and then based 7,702–7,721 through the afternoon, closing 7,709.96 (−0.18%) after a $1,840.8M sell MOC imbalance took it 6.5 points lower at 15:50 and was recovered within three minutes; the forward 8/07 book reads diffuse rather than pinned — no strike carries more than 11% of near-spot gamma — with the 7,740–7,785 shelf holding 42% of near-spot exposure as the dominant cap and 7,680–7,710 the only supportive band beneath spot, VIX closing 15.15 (−4.3%)
2026-08-05 · Wednesday
SPX opened 7,786.97 against a 7,736.52 prior close — a +50-point gap — printed the session high 7,793.68 at 09:31 ET and never looked back up, selling into a 7,720.17 low at 15:59 as near-spot positive delta exposure drained from roughly +$13.1B at the open to +$1.4B by 15:55; an afternoon bounce attempt at 14:04 failed when gamma flipped POS→NEG at 14:31, and the session closed 7,723.55 (−0.17%) with settlement gamma at the 7,700 magnet printing −$131M while the forward 8/06 book still summed net positive, call wall 7,750 and put shelf 7,675, VIX closing 15.81 after an 18.43 high
2026-08-04 · Tuesday
SPX gapped up 30 points to 7,630.62, printed a 7,629.10 low inside eight minutes and never traded back through it, then ground higher for the rest of the session — 7,698 by 11:36, 7,726 on the 13:00 break, 7,741 by 14:02 — as near-spot positive delta exposure built from +$27.9B at 10:00 to +$49.8B by 14:00 with the single heaviest strike tripling from +$6.2B to +$18.4B; after 14:00 that concentration came apart, the top strike back to +$6.5B by 15:00 while near-spot gamma kept climbing to +$988M, and the 129-point run ended at the 7,758.21 high printed at 15:46, the last fourteen minutes carrying a $4,479M market-on-close sell imbalance into a 7,736.52 close twenty-two points off the high, with VIX up 4.70% to 16.50 on a +1.79% index day and settlement gamma at the 7,735 magnet printing −$1,113M
2026-07-31 · Friday
SPX gapped up 24 points to 7,462.13 and handed the entire gap back inside forty minutes, flushing to a 7,399.83 low at 10:16 that sat 38 points below Thursday's close, with the near-spot book at its most destabilised of the session — gamma at −$130.5M and delta exposure at −$9.0B in the ±40pt band, an amplification condition rather than a floor; what turned it was the speed of the repair, both back to −$8.2M and −$1.9B by 10:40, after which price never revisited the low and spent six hours grinding higher as the heaviest positive-delta strike migrated 7,400 to 7,475 to 7,500 and grew to roughly +$23.3B while gamma at the active wall inflated from +$168.6M at 13:24 to +$1,027.7M at the bell, capping the 7,512.04 high printed at 15:53 and giving back twenty points into a 7,489.72 close with VIX down 4.04% to 16.14 after an 18.70 spike
2026-07-30 · Thursday
SPX gapped 74 points to 7,390.45 and spent the whole morning proving it, building a double bottom at 7,371.67 at 09:40 and the true session low of 7,370.98 at 11:26 before never trading there again; the advance came entirely after 13:00 as near-spot gamma on the expiring book inflated roughly sixteen-fold from +$103M to +$1.65B and the magnet stepped 7,430 to 7,440 to 7,450 underneath a tape that tracked it to a 7,448.75 high at 15:18, until a $2,105M sell-side MOC imbalance published at 15:56 pulled the last eleven points off into a 7,437.63 close, with VIX settling at 17.00 — its low of the day, down from a 20.08 print
2026-07-29 · Wednesday
Aggressor 0DTE premium ran +$39.6M into the 12:16 low while near-spot gamma sat at −$98M and delta exposure at −$9.1B — flow and structure disagreed all session, and structure won; SPX opened 7,418.16, bled to 7,343.37, and the post-FOMC rally turned the near-spot book long gamma at 14:41 only as far as the 7,450.84 high at 14:54, one point under the 7,455 call wall, before gamma broke from +$195.8M to −$719.8M and carried 134 points off the high in sixty-six minutes into a 7,316.15 close printed on the session low
2026-07-28 · Tuesday
SPX opened 7,395.55 — 17.6 points below Monday — and took it straight back to 7,413 inside the first minute, only to roll over into a 7,382.95 low at 09:48 with the book short gamma and accelerating the slide; at 11:17 ET near-spot gamma flipped long, the downside accelerant switched off, and price ground up to a 7,452.09 high at 12:57 against damping hedges rather than because of them, before the stabilization drained back out in the final half hour to close at 7,428.78 in negative gamma
2026-07-27 · Monday
SPX gapped up 52 points to 7,464 and never traded higher — the 7,480.57 high printed at 09:36, then near-spot gamma flipped negative at 10:30 and stayed there for five hours, taking price 98 points down to a 7,382.74 low at 13:18 before a slow grind back and a $684.7M MOC buy imbalance closed it at 7,413.18, just 1.20 points from Friday
2026-07-24 · Friday
SPX opened 7,406 and ground up to a 7,461 high at 12:11, rejecting the 7,470 positive-gamma call wall, before fading to a 7,397 low at 15:25; a $1.25B MOC buy imbalance lifted it back to a flat 7,412 close — a 64-point round trip that resolved nothing, leaving price mid-range between the 7,400 put shelf and 7,470 wall in a net-negative near-spot book
2026-07-23 · Thursday
SPX gapped 80 points below prior close to 7,418, tagged a 09:43 high of 7,450 — its only visit to the upper half — then bled to a 7,376 low as full-book dealer delta hit its most-negative of the day; the 32-point crawl back to 7,408 was forced-dealer-buying amplification, not a repair, and the book closed net-negative with 7,420 an overhead flip and no shelf beneath spot
2026-07-22 · Wednesday
SPX opened 12 points below prior close, reversed off a 7,485.85 low as near-spot gamma flickered and $3.1B of short delta drained and reloaded, ran to a 7,525.94 high nine points under the day's heaviest gamma wall — then gave it all back after a 14:12 gamma flip, closing at 7,498.96 on the 7,500 strike with a $1.13B MOC sell imbalance supplying the last leg
2026-07-21 · Tuesday
SPX gapped up 47 points, defended the one early test 25 points above prior close, and ground to a 7,515 high before pinning at 7,509.20 (+0.89%) — near-spot dealer delta swung from −$0.3B to +$19.4B intraday as the whole negative-gamma book from Monday repaired into a positive corridor
2026-07-20 · Monday
SPX gapped up 31 points to 7,489, topped at 7,513 just eight minutes in, then sold for six and a half hours — the low printed on the day's heaviest negative-gamma cluster at 7,440 and a $2.5B MOC sell imbalance carried the close to 7,443.28, the full gap surrendered with no gamma shelf left below
2026-07-17 · Friday
SPX gapped 86 points lower to 7,447, knifed to the 7,431 low within five minutes, then rode a dealer-unwind rally 66 points to a 12:52 high at 7,498 — which died the minute near-spot gamma turned positive. The afternoon gave two-thirds back into neg-gamma before a $2.26B MOC buy imbalance caught the close at 7,457.69 on July monthly opex
2026-07-16 · Thursday
SPX opened 7,558.80 (−14pt gap down), the 10:33 recovery high failed below Wednesday's close under a descending call wall, and after the 12:05 gamma flip the afternoon bled to a 15:49 low of 7,504.02 — where dealer books hit maximum destabilization and re-inflated violently, snapping price back to a 7,533.77 close ahead of Friday's July monthly opex
2026-07-15 · Wednesday
SPX opened 7,571.72 (+28pt gap up), tagged 7,581.50 at 10:19 ET, then flushed through two gamma-regime flips to a 12:41 low of 7,526.95 — 17pt below Tuesday's close — before the afternoon re-inflation carried it all the way back to a 7,572.40 close, with $1.27B of dark-pool volume printed right at the settled level
2026-07-14 · Tuesday
SPX opened 7,536.70 (gap up), flushed to a 7,513.23 low at 10:16 ET as near-spot GEX briefly flipped negative, then reversed hard to a 7,557.44 high just 18 minutes later at 10:34 ET — near-spot dealer delta swung from -$3.9B to +$933M over the same stretch, closing 7,543.59 right at the 7,545 call wall
2026-07-13 · Monday
SPX opened 7,547.53 (gap down), popped to a 7,565.37 high at 9:32 ET, then faded almost the entire session to a 7,506.41 low at 15:38 ET — near-spot dealer delta collapsed from +$3.7B to -$29.0B over the same stretch, closing 7,515.34
2026-07-10 · Friday
SPX opened flat, flushed 39pt to a 7,508.16 low at 10:33 ET, then ground higher the rest of the session to a fresh 7,579.93 HOD at 15:50 ET — near-spot dealer delta drained to ~$3.8B at the low before rebuilding to ~$51.8B by the close
2026-07-09 · Thursday
SPX gapped up 9pt and put in its low first — a 7,481.73 LOD at 10:21 ET testing the prior close — then ground higher all afternoon inside positive gamma to a 7,546.89 HOD at 13:48, pinning into a hardening 7,550 wall to close 7,543.64
2026-07-08 · Wednesday
SPX gapped down 27pt to open 7,476.54, flushed to a 7,421.82 LOD at 11:30 (−1.09%, VIX spiking 18.91) on neg-gamma velocity, then reversed on dealer short-delta covering and a rebuilt +GEX magnet, grinding to a 7,488.51 HOD into a 7,482.71 close
2026-07-07 · Tuesday
SPX gapped down 20.8pt to open 7,516.63, tagged a 7,536.06 HOD at 09:32, flushed to a 7,478.63 LOD at 10:42 on neg-gamma velocity, then chopped around the 7,500 magnet through the charm window into a 7,503.85 close
2026-07-06 · Monday
SPX gapped up +23.7pt to open 7,506.96, dipped once to a 7,500.97 low at 09:38, then ground higher all session on a dealer-delta floor that built to ~$46.5B and a +GEX magnet ratcheting 7,520→7,540→7,550, tagging a 7,551.31 high at 15:24 before easing to a 7,537.43 close
2026-07-02 · Thursday
SPX rallied to a 7,540.75 high at 10:14 (capped by a forming +GEX wall), flushed to a 7,427.55 low at 14:00 through real negative gamma, then a $7.1B MOC buy imbalance drove the final 10 minutes back to a dead-flat 7,483.24 close
2026-07-01 · Wednesday
SPX gapped -20.5pt to 7,478.84, flushed to a 7,449.63 low at 09:35, then rebuilt through the morning to a 7,521.81 high at 12:23 before a confirmed structural flip gave it all back
2026-06-30 · Tuesday
SPX opened flat (+0.84pt gap), LOD 7438 at 09:31 (briefly below prior close 7440.43), then grind to HOD 7508.29 at 15:18 before reversing to close 7499.36

Opened into the 7,500 fears and printed the low minutes after the bell, then ran one-way higher as dealer positioning flipped bullish — tagging the 7,600 call wall before fading into the close.
2026-06-03 · Wednesday
