Order Compliance Gateway
Prove your matching is fair.
To regulators, participants, and yourself. A pre-match decision layer that wraps your existing matching engine. Every order gets an admit, delay, or reject decision — with a reason code and replayable evidence.

You can't prove matching is fair
Regulators and participants are asking for fairness evidence. Your current answer is forensic log reconstruction after the fact — expensive, slow, and unconvincing.
Incident review is forensic reconstruction
When something goes wrong, you're parsing logs backwards to figure out what happened. There's no native record of why a decision was made at the time it was made.
Adversarial flow exploits execution gaps
Sophisticated participants exploit the gap between order submission and matching. Without a governance layer, the matching engine processes everything it receives, fair or not.
What the Order Compliance Gateway Does
The Order Compliance Gateway sits in front of your matching engine. It evaluates every incoming order against a policy framework and makes a deterministic governance decision — admit, delay, or reject — before the order ever reaches matching. Every decision produces a reason code and an evidence artifact that's replayable for regulators or incident review.
Wraps your existing engine
No matching engine replacement. No changes to order flow protocols.
Reason code on every decision
Why was this order admitted? Delayed? Rejected? The answer exists at execution time, not after.
Regulator-grade artifact pack
Replayable evidence for compliance review. No retroactive reconstruction needed.
Where It Sits In Your Stack
The Order Compliance Gateway wraps your matching engine — it does not replace it.

Governance Actions
Admit
Order proceeds to matching engine. Decision logged with reason code.
Delay
Held with reason. Released by policy when conditions are met.
Reject
Blocked with reason code and evidence artifact. Fully replayable.
Every action is logged. Every log is replayable. No retroactive reconstruction.

Fairness & Audit Metrics
PCS Fairness Score
Provable Compliance Score derived from per-order evidence artifacts. Measures governance completeness — every order evaluated, every decision logged with reason code.
Audit Bundle Integrity
SHA-256 verified evidence packs per governance decision. Regulator-ready artifacts with full replay capability. No retroactive log reconstruction.
For Compliance Teams
The Order Compliance Gateway produces regulator-grade artifact packs at execution time. When an auditor asks “why was this order handled this way?” — the answer already exists. No forensic reconstruction. No log parsing. No guessing.
- •Replayable evidence artifacts for every governance decision
