Every night we rank the US options market by liquidity. Your agent gets a small pool of contracts it can actually trade, plus the history of what setups like them did. Your agent analyzes. You decide.
about 3,500 optionable US stocks ranked nightly · a bullish pool of roughly 40 to 50 calls · no hindsight data · outcomes published, wins and losses
The whole website is free. The free MCP tier needs no card and no key. Agent Access is $29/mo with a 30-day trial.
Step one costs nothing and takes about ten seconds. Do that first, and decide whether the data is worth anything to you.
Point any MCP client at the free endpoint. In Claude Code that is one command.
claude mcp add --transport http gammarips https://mcp.gammarips.com/mcpThen ask your agent for this morning's brief.
Free tools: pool preview, daily report, regime context, market calendar, and the methodology playbooks.

Last night's pool holds 44 bullish names, one out-of-the-money call each. Here is the overnight context and the pool preview. Do you want me to work through the names by sector, or by how far out of the money the calls sit?

The harness is the daily loop: a screen, a journal, and an after-the-close review. Clone it, then open it in Claude Code or any MCP client that reads .mcp.json.
git clone https://github.com/DevDizzle/gammarips-harness.git
cd gammarips-harnessIt is a workflow, not a signal service. The harness is free. The data is what costs money.
See it on GitHubStart the trial on the pricing page. Create your key on the account page. It is shown once, so copy it then.
export GAMMARIPS_MCP_KEY="<your key>"The harness reads that variable from your shell. Never hardcode the key.
Pro tools: liquidity grading, per-name signal detail, outcomes history, contract replay, and the full pool. The harness screens tradeability before it considers a story, so the loop needs them.
A chat client that cannot send a header adds https://mcp.gammarips.com/pro instead and signs in.
Three commands, run in the harness.
/trade morning: screen the pool, rank a short list or call no-trade
/review after the close: score every pool name, not only yours
/coach on demand: your own record, read back to youYour agent reaches its own contract and its own exit, sized to your risk. There is no pick endpoint, on purpose. Two agents on the same pool should reach different answers.
Paper-traded by default. Educational only, not investment advice.
Every name in the pool is free to read on this site. The pool is not ranked, and nothing here is a recommendation.
SLB BULL $60C Sep 18 '26. The institutional flow shows significant accumulation of long-term upside premium following the strategic $3.4 billion acquisition of Kelvion, targeting high-growth data center infrastructure alongside the completed integration of S&P Global's upstream software. Risk factor: unexpected downturns in international offshore oilfield service spending or integration friction within the newly established non-oil and gas business lines.
PURR BULL $14C Sep 18 '26. The institutional flow shows significant call premium concentration at the out-of-the-money $14 strike following the company's blockbuster fiscal 2026 earnings report and high-margin AI platform growth. The underlying spot at $12.77 sits within a strongly rising technical trend, indicating that institutions are positioning for a breakout toward the 52-week high near $14.14. Risk factor: Sudden shifts in digital asset volatility or profit-taking following a rapid multi-week run could temporarily halt momentum prior to the September expiration.
MRNA BULL $170C Sep 18 '26. Institutional flow shows massive high-conviction positioning concentrating in out-of-the-money calls, looking past a temporary pullback driven by an analyst downgrade and dilution fears from a convertible senior notes offering. This aggressive positioning reflects a strong long-term bet on the validation of the personalized mRNA cancer vaccine platform ahead of full Phase 3 data presentations later this year. Risk factor: Valuation metrics remain highly elevated relative to near-term commercial revenues, making the underlying stock susceptible to sharp pullbacks if upcoming pipeline readouts fail to meet high growth expectations.
KHC BULL $25.5C Sep 11 '26. Institutional options flow aggressively targeted the $25.5 strike call contract expiring on September 11, 2026, positioning for a rapid recovery from a 3% sector-induced dip. This bullish momentum coincides with the final week of trading on the Nasdaq before the company officially transitions its stock listing to the NYSE. Risk factor: Continued volume erosion and persistent pressure on lower-income consumer spending could stall the anticipated rebound.
HOOD BULL $130C Sep 18 '26. Institutional flow focused heavily on out-of-the-money long-dated calls, reflecting strong momentum following bullish analyst reports on its new business avenues and the highly successful launch of Trust Accounts. Risk factor: The primary uncertainty stems from regulatory scrutiny on prediction markets and retail trading platforms, which could dampen the projected expansion rate of these high-margin services.
This runs every trading night, at 23:00 ET.
Two safety rails guard the paper cohort's entry, not this list. The cohort drops any name with earnings in its hold window and stands down when the VIX sits above VIX3M. The pool you browse is not earnings-screened, so check each candidate yourself.
Liquidity decides membership. Not unusual activity. Flow gives your agent context, and it does not choose the pool. We rank the most liquid names and then choose one contract inside each. If we ranked the most liquid contracts instead, you would get SPY and QQQ every day.
We moved the scan to liquidity first because the old funnel picked contracts that were harder to trade. On the 60 trading days ending 2026-08-14, the share of candidates with no fill at 10:00 ET measured 40.5% under the old funnel and 6.1% under this one. Those are study numbers on that window. They are not a property of today's pool, and they are not a claim about returns.
If you bought every contract in the pool every morning and closed on one fixed same-day rule (in at the 10:00 ET mark, out at +40% or −30%, flat by 15:45 ET), you would lose money. We know because we tested it, and we publish the record. That is exactly why there is no pick endpoint. The winners sit inside the pool, and the outcome data shows how far each contract ran and how far it fell. Which ones, and how they get traded, is analysis. That is your agent's job. Anyone who sells you a shortcut past that step is selling you a story.
We also tested whether the pool beats random. Over 87 trading days, against liquidity-matched and random optionable controls, we could not show that it does. The test can see a difference of about 5 percentage points per trade, so read that as no large edge rather than no edge. We sell the data layer and the outcome history. We do not sell a ranked list.
I trade my own tool every morning. That is my own process, not a signal to follow. The public receipts are paper-traded and educational only. See the disclosures.
Pick your client. The free tier needs no card, no key, and no signup. Agent Access ($29/mo, 30-day trial) opens the pro tools. Paste a key if your client sends headers. If it cannot, add the pro endpoint and sign in instead. Every tab reaches the same 9 tools.
