They are lost to rules breaches — a daily-loss limit crossed by one oversized position, a [trailing drawdown](https://hadalinstruments.com/glossary/trailing-drawdown/) clipped in a correlated cluster the evaluee never saw as one trade. The Risk Guardian is instrumentation for exactly that failure mode. *How close are you?* is the only question a trailing rule ever asks, and your account balance is the wrong place to look for the answer. What the floor does depends on which of three architectures your rule text describes: under an **intraday-trailing** rule it follows every new equity high upward, including unrealised profit, and never comes back down; under an **end-of-day-trailing** rule it follows a daily balance instead, so an unrealised high does not move it at all; under a **static** rule it does not move. In all three the room left after a peak is not simply the allowance printed in the rulebook, and in two of them it is not what an intraday reading would tell you either. The Guardian states that distance live, in the unit that governs the next order — how much adverse movement, at current sizing, ends the evaluation — and restates it every time the [high-water mark](https://hadalinstruments.com/glossary/high-water-mark/) moves. What you do about that distance is still your decision; the instrument’s job is that you never have to guess how close it is. ## What it measures Each evaluation account is watched against the rulebook it was issued under, and a second challenge under a different rulebook is a second set of arithmetic. - **Halt distance, live.** Your real-time distance to every rule that can end the evaluation — daily loss, max [drawdown](https://hadalinstruments.com/glossary/drawdown/), trailing thresholds — expressed in the only unit that matters: how much adverse movement, at current sizing, kills the account. The single-point version of that arithmetic is free and on this site: the [trailing drawdown calculator](https://hadalinstruments.com/tools/trailing-drawdown-calculator/) computes one floor from numbers you type. What the instrument adds is that it recomputes on every fill and folds correlated positions into one exposure. - **Correlation-adjusted heat.** Five positions in correlated pairs are not five risks; they are one large one wearing five tickets. The Guardian computes effective exposure across the book so the size you *feel* matches the size you *hold*. - **Risk-of-ruin surfaces.** Given your sizing grid and the evaluation’s rules, the probability terrain of breaching before passing — recomputed as the account moves, published with its assumptions visible. The single-point version from rules you type is free and on this site: the [prop evaluation survivor](https://hadalinstruments.com/tools/prop-evaluation-survivor/). - **Sizing grids.** What position size the rules actually permit from here, precomputed — so the decision under pressure is a lookup, not an estimate. ## What it does not do The Prop-Evaluee Risk Guardian does not improve your entries. It has no opinion on your strategy. It polices the boundary between your strategy and the rules you agreed to — because the strategy cannot pay off from a breached account. ## Who it is for Evaluees who paid for a funded-account challenge and would prefer their risk of failing it to come from the market, not from arithmetic they didn’t run. ## The ship gate No instrument is sold until it does what this page says it does. Where a page is written in the future tense, that tense is a statement about timing rather than a hedge about capability: the instrument is not finished, so it is not listed as available, not priced as available, and not sold. It waits. Nothing described in this catalogue is a placeholder that will quietly disappear. An instrument that turns out to be wrong gets a [kill-ledger entry](https://hadalinstruments.com/kill-ledger/), not a deletion — which is the only version of that promise anyone can check. ## Commercial terms Published in full, pre-launch, so they can be read and checked rather than requested. Every figure is an anticipated indication I have set and not yet ratified, and every derived figure is the arithmetic of the one above it — shown, not asserted. Nothing here is purchasable: there is no checkout on this site. ### Why Prop-Evaluee Risk Guardian is priced the way it is - **What the figure buys** — A subscription covers one evaluation account, watched against the rulebook it was issued under: live distance to every rule that can end it — daily loss, maximum drawdown, trailing thresholds — expressed as how much adverse movement at current sizing kills the account, alongside correlation-adjusted exposure across the whole book, risk-of-ruin surfaces recomputed as the account moves with their assumptions visible, and sizing grids precomputed so the decision under pressure is a lookup rather than an estimate. The boundary is deliberate. It takes no view on your entries, holds no opinion on your strategy, and neither places nor blocks a trade; it measures the distance between where you are and where the rules end the evaluation, and closing or widening that distance stays your decision. It also cannot recover an account that has already breached. - **Why it is priced this way** — Monthly, and per evaluation account, because the account is what is being watched: halt distances, trailing thresholds and the permitted sizing grid are properties of one rulebook, and an evaluee running a second challenge under a different rulebook has a second set of arithmetic to keep. The quoted unit is monthly because an evaluation is a finite episode that ends in a pass or a breach, and a month is the step an evaluee can stop at when the episode does. The commitment ladder on this page still applies to anyone who wants it — a desk running evaluations continuously is not buying an episode but a standing capability, and the longer terms price that. Desk editions exist for the other case — a firm supervising several evaluees at once, which needs the same boundary held across every account beneath it rather than an unrelated copy of the instrument per person. - **What the alternative costs** — You can run the arithmetic yourself, and the mathematics is not hard: the rules are published in the challenge agreement and halt distance is subtraction. What is hard is doing it on every fill, mid-session, while correlated positions quietly make the book larger than the ticket count suggests — that is where the effort actually lands, and it lands heaviest at the moment attention is worth most. A challenge dashboard, where your firm provides one, generally reports where the account stands against its limits now. That is a state, and what governs your next order is a forward distance at your present sizing with correlated positions folded into one exposure — a different computation rather than a worse dashboard, and worth checking against whatever your own firm gives you before paying for it here. Doing nothing costs nothing until a limit is crossed by arithmetic nobody ran, at which point it costs the evaluation and the fee that bought it. Every figure on this page is an anticipated indication awaiting ratification, and nothing here is purchasable. The reasoning above is published for the same reason the arithmetic below is: a price you can interrogate is worth more than a price you have to accept. ### The two-SKU split Two routes, side by side, with the standing rule rendered as a rule: the hub tier is priced at or below its marketplace equivalent, so the hub is always the better of the two. No marketplace SKU has been listed anywhere yet, so that cell says so instead of showing a figure nobody has set. Route | What it is | Anticipated | Marketplace SKU | Where this instrument ships through a platform marketplace, that SKU is the fully-functional standalone tier — the complete battery, running natively on your platform, no external account required. Never paid-but-crippled. | NOT YET LISTED | Hub subscription (this site) | The deepening: hosted runs, the published methodology behind them, and the content-hashed artifacts that let a stranger re-derive the result. This is the tier the figure on this page prices. | £29/mo · £290/yr | The price rule The hub tier is priced at or below its marketplace equivalent. That is a standing rule the pricing table is rendered against, not an offer: a marketplace platform takes a percentage of every sale it processes, and that saving goes to the hub subscriber rather than to Hadal, so a platform fee can never invert your margin. No marketplace SKU has been listed yet, so the cell above reads NOT YET LISTED and the rule stands as a commitment rather than a comparison you can run today. Also directed for this instrument - from £99/mo desk editions £990/yr on an annual term — twelve months for the price of ten ### The commitment ladder One month less paid per year of service, per step, taken off this instrument's own anticipated annual rate of £290/yr — the first of the 2 figures directed for it, the rest in the two-SKU split table. The rate is held at the figure you sign for the whole term, so a multi-year commitment fixes the price as well as reducing it. Term | Months paid per year | What it means | Anticipated | Monthly billing | 12 | £29/mo × 12. Twenty per cent more than the annual term — that is the uplift for paying monthly, not a discount for paying annually. | £348/yr | 1-year term | 10 | Twelve months of service for the price of ten. This is the annual rate every band below is taken off. | £290/yr | 2-year term | 9 | Ten per cent off the annual rate, held at that figure for the whole term. | £261/yr | 3-year term | 8 | Twenty per cent off the annual rate, held at that figure for the whole term. | £232/yr | Three years for what two years of monthly billing costs Eight months paid per year, across three years, is 24 months paid for 36 months of service — one year in three carries no charge. On this instrument the three-year term totals £696 . That is 24 × £29 = £696 , and two years billed monthly is £348 × 2 = £696 . The same money. It buys three years instead of two, and the arithmetic is on the page so you can check it rather than take it. ### Group licences, across entities Licensing here is per account or per desk, not per seat, so a seat band does not apply and none is offered — applying one would be a category error dressed as a discount. The scaling axis here is **entities**: where the same instrument is run by more than one legal entity, desk, fund or network inside a group, the licence is negotiated as a single group licence rather than replicated entity by entity. Multi-network clients are exactly the case this exists for, and the commitment ladder above applies to a group licence on the same terms it applies to a single one. ### Commercial routes Pricing scales on entities and on term — one negotiated group licence across desks, funds and legal entities, never a seat band. [Licensing — seat bands, group licences and multi-year terms in full](https://hadalinstruments.com/licensing/) ### Support - Tier **Standard** at this instrument’s base contract — ticket, first response targeted at three business days . Support tier follows the annual contract value, not the price of a single unit — more seats, a suite licence or a group agreement raise the contract value and can raise the tier with it. [Support — the tiers, the ticket-only channel model, and what a target does and does not promise](https://hadalinstruments.com/support/) ### Trial mechanics The trial runs on the hub tier — thirty days, a full natural proof cycle, disclosed in plain words before you start it and cancellable in one step; none of it is live yet. [Trial mechanics in full, by delivery class](https://hadalinstruments.com/licensing/#trial). ### Read before you commit The documentation is published ahead of the product on purpose — intended behaviour is only a commitment if it exists first. Start with [installation and first run](https://hadalinstruments.com/docs/install/), then [the limits](https://hadalinstruments.com/docs/limits/): the conditions under which this instrument refuses to produce a number are the part worth reading before you pay. The full centre is at [/docs/](https://hadalinstruments.com/docs/), and the [support model](https://hadalinstruments.com/support/) states what a ticket does and does not cover. ## Questions and answers Answered from what this instrument publishes about itself. Nothing below is attributed to a customer, because there are none yet. ### Does it have an opinion on my entries? None. It polices the boundary between your strategy and the rules you agreed to, because a strategy cannot pay off from a breached account. ### Why does correlation matter to a drawdown rule? Because five positions in correlated pairs are not five risks; they are one large one wearing five tickets. Effective exposure is computed across the book so the size you feel matches the size you hold. ### What is halt distance? Your live distance to every rule that can end the evaluation — daily loss, max drawdown, trailing thresholds — expressed as how much adverse movement at current sizing would end the account. ### Can I buy this instrument today? No. Nothing on this site is on sale — there is no checkout, no card capture, and no product account to create. Every figure on this page is an anticipated indication I have set so it can be read and compared, not an offer, and final pricing awaits my ratification. The launch list is the only thing you can join today. ## Change log NOT YET PUBLISHED Prop-Evaluee Risk Guardian has not shipped, so there is nothing to record. When it does, every version lands here — dated, append-only, written by a person, and including the changes that removed a capability rather than added one. ## Where this sits Prop-Evaluee Risk Guardian is one of the instruments in the [Desk Discipline suite](https://hadalinstruments.com/suites/desk/).
