gateHFT — High Frequency Trading Execution Gate
// The problem

At microsecond scale, human review is no longer possible.

High-frequency trading happens at a scale where a subsequent human review is effectively impossible. The gate therefore seals every order deterministically, including the algorithm hash, so it stays re-computable afterward which software version placed which order.

// Architecture

Four sub-gates, cascading.

Market abuse is dispositively mandatory, meaning a hit on spoofing or layering is never compatible with a documentation_only mode.

SUB-GATE 1
Algorithm Bias
Determines a deterministic bias score and compares it against the documented threshold (default: 0.1). The algorithm hash is sealed, binding the software version to this specific order.
bias_score · bias_threshold · algorithm_hash
SUB-GATE 2
MiFID II MAR Market Abuse
Checks for spoofing (fake orders to condition price) and layering (multiple orders at different price levels to fake market depth). Both are dispositively mandatory.
spoofing_detected · layering_detected
SUB-GATE 3
Latency Arbitrage
Checks whether the order was placed within a critical latency window (default: under 5 ms), which would indicate exploitation of delayed price feeds.
latency_window_ms · latency_arbitrage_flag
SUB-GATE 4
Venue Authorization
Confirms that the trading venue was validly authorised at execution time T=0. A subsequent change of authorisation would be a severe violation.
venue_authorized_at_t0
An important distinction: market abuse is never documentation-only
BLOCK_HFT_MARKET_ABUSE_SPOOFING and BLOCK_HFT_MARKET_ABUSE_LAYERING are dispositively mandatory. Unlike purely documentary sub-gates, there is no material_block_mode_used:false path here, a hit always blocks bindingly.

// Clarification

What gateHFT is not.

  • Not automatic recognition by a market regulator. The gate delivers a cryptographic proof, not regulatory admission as evidence.
  • Not an independent market surveillance system. The gate seals order attestation, it does not replace the venue's ongoing market surveillance.

For venues and regulators that want to make algorithmic orders forensically re-computable.

GATE CATALOG · REGULATORY DETERMINATION DOMAIN

gateHFT

gateHFT determines encoded algorithmic-trading, order, venue, timing and market-microstructure conditions. The gate contributes a bound regulatory determination state; it creates neither regulatory authority nor Execution Permission.

AUTHORITY BOUNDARY

MARKET-MICROSTRUCTURE STATE IS NOT TRADING AUTHORITY.

CAN

  • deterministically evaluate encoded regulatory conditions
  • bind determinations to source, scope, time and input state
  • surface missing, expired or conflicting regulatory dependencies
  • produce attributable evidence for the concrete determination

CANNOT

  • replace a regulator, supervisor, court or competent institution
  • create legal or regulatory authority through score, consensus, AI or administration
  • turn a gate PASS into an Execution Right on its own
  • mint an ExecutionCapabilityToken on its own
REGULATORY STATE

Regulatory determination is evidence. Not regulatory authority.

SOURCE

Authoritative source

The relevant rule must originate outside the system from a legitimate normative or institutional source.

SCOPE

Defined matter

The determination is limited to the encoded subject, entity, transaction or operation under review.

TIME

Point-in-time state

Effective dates, transition periods, expiry and version state remain explicit.

INPUT

Canonical input

A reproducible determination requires a defined canonical input state.

DEPENDENCY

Dependencies

Missing or contradictory dependencies remain visible rather than being converted into invented permission.

EVIDENCE

Bound evidence

The resulting state can be bound to source, input, scope and time for later verification.

RELATED DETERMINATION DOMAINS

Regulatory domains compose. They do not confer authority on one another.

Only scope-relevant determinations become dependencies in Execution Rights resolution. The links shown are not a universally mandatory sequence.
