Use when estimating how much extra delay a matching engine adds as inbound message rates approach its capacity, and converting that utilisation into a quoting directive. A closed-form model, not telemetry.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

## When to Use

Use this skill in high-frequency market making and microstructure simulation to answer one
question: *given the message rate the engine is currently absorbing, how much extra delay
should I assume before my cancel lands, and should I still be quoting?* During volatility
events (FOMC, CPI, index rebalances, crashes) inbound message rates at CME Globex, Nasdaq
INET and Eurex T7 spike by an order of magnitude. Because queueing delay grows as
$1/(1-\rho)$, an engine at $\rho = 0.9$ adds nine service times of delay where an engine at
$\rho = 0.5$ adds one. That delay lands on your **cancel** messages, which is what converts
a resting quote into a sniped quote.

## When NOT to Use

- **As a measurement.** This is a closed-form model, not telemetry. If you have real
  wire-to-wire timestamps, use them — see `tick-to-trade-latency-measurement` and
  `colocation-latency-budget-accounting`. This module is for the case where you can observe
  a *message rate* but not the engine's internal delay.
- **When $\lambda$ is a session average.** M/M/1 assumes Poisson arrivals. Real order flow
  is strongly clustered and self-exciting, so a model fed the daily mean rate materially

How to install

The exact contents, by fingerprint
mdr add himanshuj16/algo-trading-skills/exchange-matching-engine-behavior-under-load@sha256:c1f96bced585c94a

The line at the top of this page pins the label v2.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
