> Instruments that measure the claims trading makes: feeds, backtests, desk risk, chart vocabulary — method first, artifacts hashed, zero performance claims. - Canonical: https://hadalinstruments.com/ --- Instrument-maker · pre-launch # Measurement instruments for the claims trading makes — feeds, backtests, desk risk, chart vocabulary. inside the subhead followed by a newline and the next sentence; HTML compression collapsed that newline away and the live page rendered "…want quality.We searched for…" (the copy then carried the pre-OR-062 plural voice). Two block elements cannot collide, so the fix carries no whitespace hack and cannot regress. --> I went looking for honest, instrumented trading tools. I couldn't buy them, so I built them. Broker feeds audited, backtests tested for honesty, desk risk held to its own written rules, chart vocabulary measured rather than believed: each instrument publishes its measurement method before it runs, hashes the artifact it measured from, and states in writing what it does not establish. **Zero performance claims** — not in the copy, not in the examples, not ever. Hadal *(/ˈheɪ.dəl/)* — from the hadal zone, the ocean's deepest realm.

The strip below is where a measured fact stands beside the hash of the artifact it was computed from. Not one of them exists yet — so it carries the three commitments instead: what will be published, and the page that will carry it. Each seal below becomes that artifact's hash on the day it lands, and not one day earlier. - 01 /03 Pre-registration The feed battery, written down before it is run Every dimension, threshold and exclusion rule of the fidelity battery, fixed and hashed before the first broker feed is touched — so the auditing method cannot be tuned afterwards to flatter a result. sha256 NOT YET PUBLISHED [Feed & Execution receipt page](https://hadalinstruments.com/methodology/feed/) - 02 /03 Computed artifact An overfit audit published with what it audited The probability of backtest overfitting, the deflated Sharpe and the effective number of independent trials — each published beside the backtest they were computed from and the code version that produced them. sha256 NOT YET PUBLISHED [Backtest Honesty receipt page](https://hadalinstruments.com/methodology/backtest/) - 03 /03 Raw corpus Broker portrait #1, re-derivable by a stranger One broker feed measured on the pre-registered battery and published as a profile, with the tick corpus downloadable and content-hashed so the published figures can be recomputed independently. sha256 NOT YET PUBLISHED [The Observatory](https://hadalinstruments.com/observatory/) Founding thesis > "I searched for it, couldn't buy it, and built it — module by module. First-frustrated-customer validation." The category — honest, instrumented trading tooling — doesn't exist because the market's incumbents discovered that promises sell better than measurements and stopped trying. The addressable customer is the **burned-serious minority** — traders who want an instrument, not a lottery ticket. They are a small fraction of the market and the only fraction that retains. What I measure vs. what gets sold Publication cadence floor Measured per broker Two-sided coordination Detected Spread regime detection Classified Freeze/rollover behaviour Instrumented What the industry sells instead — these three rows describe other people's review sites, not Hadal: Industry standard disclosures ★★★★★ Typical "reviews" Affiliate links Methodology published Never Instrument Suites ## Seven suites. One discipline. Each instrument earns its place by solving a problem nobody else will touch. I don't resell external analytics or white-label third-party models — nothing here is someone else's engine with my name on it, and whatever has been built was built by me. What is running, what is on hold and what is still a design differs across the catalogue, and each instrument's own page states which it is. The mathematics is mostly the field's own: the [probability of backtest overfitting](https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2326253) and the [deflated Sharpe ratio](https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2460551) are López de Prado's, the [annualisation correction](https://doi.org/10.2469/faj.v58.n4.2453) is Lo's, [HAR-RV](https://doi.org/10.1093/jjfinec/nbp001) is Corsi's. Where I arrived somewhere the literature had already reached, I say so. Where I got there on my own, I publish the reasoning so you can check that too. What makes any of it worth paying for is the part nobody does — guarding the assumptions, refusing to render a number when they fail, and publishing the method so both can be checked. The field is not short of mathematics. It is short of anyone enforcing the conditions the mathematics requires. 01 /07 ### [Feed & Execution](https://hadalinstruments.com/suites/feed/) Publication cadence, coordination structure, staleness distributions and [spread regimes](https://hadalinstruments.com/glossary/spread-regime/) — measured on your own broker feed.

The zero is pinned by policy. The one is a published post-mortem. Nothing on this plate describes a result. Those are instruments you run yourself. If you would rather one measurement was run *for* you — on your own statement, by me, ending in a written report — that is [the assay desk](https://hadalinstruments.com/assays/). The whole menu and every anticipated price are published there. Intake is not open yet, and the page says so before it lists a single assay. Simulated demonstration ## A broker feed has a grammar. I measure it instead of trusting it. The tick panel here is a simulation of what a measured broker feed looks like: every tick timestamped, every gap visible, every pattern named. The first real portraits publish with their raw, content-hashed artifacts. - **Cadence floor** — NOT YET PUBLISHED measured value - **Event clock** — ms-resolution instrument spec - **Non-crossing** — enforced instrument spec EURUSD · simulated tick stream SIMULATED SIMULATED Synthetic ticks drawn in your browser from a fixed pattern. No broker, no feed, no measurement — the panel shows the shape an instrument reads, never a result it produced. Process Receipts ## Receipts are the marketing. A receipt is cheap to publish and expensive to fake. That asymmetry is the whole strategy — and it is legible to exactly the customers I want. 04 published 01 in force, unpublished 02 not yet published Zero performance claims Constitution Agent-governance constitution Every agent session that touches this product is bound by a written constitution: no fabrication, no self-attestation, receipts or it did not happen. PUBLISHED [Read the disciplines](https://hadalinstruments.com/about/) Forensic audit Agent fabrication caught In July 2026 an agent working on my core engine fabricated results and declared the system "COMPLETE" when nothing worked. I caught it, documented it, and published the post-mortem. PUBLISHED [Read the post-mortem](https://hadalinstruments.com/research/the-burned-door/) Definitions Every term defined before it is used The vocabulary a measurement depends on is published as a glossary, so a reader can check what a word means here before deciding whether a claim built on it is worth anything.

The site cannot ship a number that does not trace to a real artifact. Enforced in CI · not itself a published artifact Pre-registration Feed fidelity battery The battery’s definitions and thresholds are written down and hashed before any broker is touched, so the method cannot be tuned to flatter a result.

Each broker is measured on the same dimensions and published as a profile you read — never squeezed into a single score, because one editorial number is the easiest thing in this industry to buy. The value is that a stranger can check my work: every published figure ships with the data and the method needed to **re-derive** it independently.

Then I built the constitution that makes it impossible." The core asset is not any single module. It is the discipline culture — mandatory internal structures, receipts, [pre-registration](https://hadalinstruments.com/glossary/pre-registration/), retraction with original errors preserved verbatim, the register that caught a fabricating agent and two honest ones compressing. Receipts promise nothing about returns, which is precisely why they are safe to publish and hard to counterfeit. **Filtering is the feature** — these instruments tell you things you may not want to hear, and that selects the buyer. What survives the funnel retains.
