# Signal scan The desk's earlier versions waited for the user to bring an idea. This skill is how the desk brings the idea to the user, at the bar it matters, without any Bot forecasting anything. Three producers write to one file; the Desk Lead reads it; the four clocks decide the tier. ## The signals file `/workspace/trading-desk/signals/YYYY-MM-DD.md`, UTC, append-only, one line block per item. Chat is for exceptions; this file is the steady flow. Every block carries a kind, a UTC time, a source, the numbers and their arithmetic, and a `next:` owner. | Kind | Producer | When | | --- | --- | --- | | `SCAN` | Market Analyst | on the scan routine, hourly by default | | `CATALYST` | Research Analyst | T-72h, T-24h, T-1h before each calendar entry on a held, SA-covered or watched market | | `RULE FIRED` | Strategist | on the closed bar where a frozen rule's condition is true | | `RULE STALE` | Strategist | one bar after a fire with no fill | | `WATCH COULD NOT TELL` | any watch owner | when a feed or read fails past its staleness bound | Nothing in this file is a recommendation. A `RULE FIRED` block is a fact about a frozen rule plus that rule's measured record. ## The universe scan Owner: Market Analyst. Inputs, one read per endpoint per market per run, against the cached `data/exchangeInfo.json` list of `status: trading` markets: ``` /v2/ticker/24hr price, change, volume /v2/premiumIndex funding rate, next funding time /v2/openInterest OI i
