What we'll say. What we refuse to say.
Plain language, by design. Here is how every level on your chart is built, what it is not, and the proof pages you can check without us. We never fabricate proof; that restraint is the credibility.
How a level gets to your chart.
Inputs
Options open interest and implied volatility per strike, every listed expiry, for index ETFs, futures proxies, sectors, single stocks and, for Bitcoin and Ethereum, the public Deribit order books. Refreshed about every ten minutes. No price feed is required to read the Library.
Computation
Call Wall and Put Wall are the strikes where call and put gamma concentrate above and below spot. The Gamma Flip is the zero crossing of net dealer gamma, and since v4.2 we also compute our own Zero Gamma by repricing the whole chain, with a band that says how sharp the crossing is. Focus levels are the next strikes that stand out, each tagged with why. Forecast bands come from the risk-neutral density and the session's charm and vanna hedging flow. Same rules every day, published with each release.
Normalization
Futures read their options proxy and are converted with the live ratio (NQ from QQQ, ES from SPY); indices, ETFs, stocks and crypto draw in their own price space. Every response is one coherent snapshot, stamped with its time and its method: Signed-flow LIVE from classified order flow, or Settlement OI.
Display
On your platform: TradingView through the Chrome overlay and a Pine block, and native builds for NinjaTrader, Sierra Chart, MotiveWave, ATAS and Quantower. Density, families, labels and palette are yours. The Indicator never recommends a trade.
Cadence & limits
Levels refresh about every ten minutes; the overlay polls roughly every forty seconds during market hours. Locked mode freezes two snapshots a day — the RTH map at 9:30 AM New York time, the overnight map at 6:00 PM New York time — so everyone reads the same map for that session. Reading from outside US hours means whichever of those two snapshots is current, which can be several hours old. Known limits ship with every release note, and two pages let you check the record without us: level statistics session by session, and twelve years of NQ, ES and SPX history.
When the data isn't there, the product says so.
No silent fallback. No partial render to nudge a purchase. The reader always sees the true state. Check the record yourself: level statistics, NQ history, ES history, SPX history.
Shown when inputs are not currently published. No silent fallback to a guess.
Shown to non-subscribers. The Indicator never partially renders to nudge a purchase.
Shown when the last refresh exceeds the documented cadence, and outside market hours the badge says CLOSED rather than pretending. The reader always sees the age.
We have not worked for a hedge fund. We do not invent users, partners, revenue or performance.
No institutional badge is shown anywhere on this site. Real testimonials will be added only with written consent — never before. The levels never guarantee a result.
