Market Context & Problem Statement

The Prop Trading Landscape

Proprietary trading has grown from a boutique sector into a global, institutional marketplace. Firms now operate across multiple jurisdictions, manage thousands of traders, and handle billions in capital. Yet the market remains:

Non-standardized — no shared definitions of risk, transparency, or compliance
Non-benchmarked — no neutral reference point for comparison
Non-auditable — evidence is fragmented, contradictory, or proprietary
Non-institutional — treated as a niche market without formal structure

Institutional Gap

Regulatory bodies, institutional investors, and market participants lack a consistent, measurable view of structural quality. Decisions are made on reputation, anecdote, or incomplete public data. This creates opacity, reduces trust, and increases systemic risk.

GTIXT as Solution

GTIXT provides the missing institutional layer: a neutral, auditable, publicly available index that measures structural quality, not performance or returns. It serves as the reference standard for the prop trading industry.

GTIXT Objectives & Scope

Core Objectives

🎯 Standardization

Establish a common measurement framework for structural quality across the industry.

⚖️ Neutrality

Measure facts, not opinions. No commercial influence, no paid positioning.

📋 Auditability

Every input, score, and decision is traceable and reproducible.

🔐 Integrity

Data is cryptographically verified and published as immutable snapshots.

👁️ Transparency

All rules, inputs, and evidence are public and machine-readable.

📊 Institutional Grade

Built to institutional standards: versioned, governed, and auditable.

Scope & Inclusion Criteria

GTIXT measures proprietary trading firms that offer funded trading programs or challenge-style evaluations. Inclusion requires:

Sufficient public documentation to compute a score
Verifiable website, regulatory filings, or regulatory presence
Active operations within the past 12 months
Ability to maintain auditability and reproducibility

Out of Scope

GTIXT does not measure:

Trader performance or returns
Profitability or financial stability
Market impact or systemic risk
Subjective quality or culture
Future success or investment potential

Architecture & Data Pipeline

System Architecture

GTIXT operates as a multi-stage deterministic pipeline:

Agent A

Crawl

Ingest public data from firm websites, regulatory databases, and public disclosures

→

Agent B

Validate

Extract, normalize, and store evidence with timestamps and source URIs

→

Scoring

Score

Apply deterministic rules to compute 5-pillar scores and final index

→

Agent C

Gate

Enforce data quality, NA policy, and consistency thresholds

→

Publish

Release

Create immutable JSON snapshot, compute SHA-256, sign pointer

Evidence Model

Every data point includes:

pillar

Reference pillar (e.g., transparency, risk_model)

metric

Specific metric within pillar (e.g., disclosure_completeness)

value

Extracted value (e.g., "documented", "yes", "0.85")

source_uri

URL or reference to source document

captured_at

ISO 8601 timestamp of extraction

Methodology: 5-Pillar Framework

GTIXT v1.1 scores firms on five pillars, each weighted and normalized. The final index ranges 0–100.

Scoring Formula

GTIXT Score = (T × 0.27) + (P × 0.27) + (R × 0.21) + (L × 0.15) + (S × 0.10)

Where T = Transparency, P = Payout Reliability, R = Risk Model, L = Legal Compliance, S = Reputation & Support

Pillar 1: Transparency (25%)

Public disclosure of rules, pricing, and operational structure. Metrics include rule availability, fee documentation, withdrawal policy clarity, and compliance certifications.

Rules PublishedFees DocumentedGovernance DisclosedCompliance Certified

Pillar 2: Payout Reliability (25%)

Track record and reliability of profit payouts. Metrics include historical payout rate, withdrawal success rate, payment speed, and evidence of consistency.

Payout RateWithdrawal SuccessPayment SpeedConsistency Track

Pillar 3: Risk Model (20%)

Quality and transparency of risk controls. Metrics include documented risk limits, VaR disclosures, position sizing rules, and equity protection mechanisms.

Risk LimitsVaR ModelPosition RulesEquity Guard

Pillar 4: Legal Compliance (20%)

Regulatory registration, compliance history, and legal standing. Metrics include regulatory licensing, sanctions history, dispute records, and jurisdiction tier.

RegistrationSanctions CheckDispute RecordJurisdiction Tier

Pillar 5: Reputation & Support (10%)

Community reputation, customer support quality, and institutional backing. Metrics include support availability, review aggregates, institutional partnerships, and media presence.

Support QualityReviews & RatingsPartnershipsMedia Presence

NA Policy & Determinism

Missing data (NA) is handled deterministically: metrics without sufficient evidence default to a neutral baseline rather than a penalty. This prevents data gaps from unfairly penalizing firms with incomplete public records.

Deterministic Scoring: Given identical inputs, the algorithm always produces identical outputs. No manual adjustments, overrides, or subjective interpretations are permitted.

Versioning & Backward Compatibility

Methodology changes follow semantic versioning:

Major versions (v1 → v2): Breaking changes to pillar definitions or weights
Minor versions (v1.0 → v1.1): New metrics or enhanced data sources (backward compatible)
Reproducibility: All past snapshots include version metadata, allowing historical score recomputation

Integrity Model & Verification

Snapshot Lifecycle

Each GTIXT release is an immutable JSON snapshot with cryptographic proof:

Snapshot Created

All ranked firms + metadata serialized to JSON

Hash Computed

SHA-256 hash of entire snapshot

Pointer Created

Metadata object with version, timestamp, hash, object path

Published

Snapshot + pointer released to public storage

Verified

Any party can download, hash, and verify integrity

Pointer Format

{
  "object": "s3://gtixt-data/snapshots/2026-02-01/snapshot.json",
  "sha256": "a3f2e1c9d7b4e6f1a2c3d4e5f6g7h8i9j0k1l2m3n4o5p6q7r8s9t0u1v2w3x4y5z6",
  "created_at": "2026-02-01T00:00:00Z",
  "version": "1.1",
  "count": 847,
  "schema": "snapshot_v1"
}

Public Verification

Any user can verify snapshot integrity with standard tools:

# Download latest pointer
curl /snapshots/universe_v0.1_public/universe_v0.1_public/_public/latest.json -o latest.json

# Download latest snapshot
OBJECT=$(cat latest.json | jq -r '.object')
curl /snapshots/universe_v0.1_public/$OBJECT -o snapshot.json

# Verify hash
sha256sum snapshot.json
# Output: a3f2e1c9... snapshot.json

# Compare with published pointer
cat latest.json | jq -r '.sha256'
# Output: "a3f2e1c9..."

Audit Trail

Every firm record includes:

Historical scores across all versions
Evidence trail with timestamps and sources
Update changelog (when data changed and why)
Confidence metadata and NA indicators

Multi-Level Hashing & Cryptographic Verification (v1.1+)

GTIXT v1.1 introduces institutional-grade cryptographic verification across multiple hierarchy levels:

Evidence Level: SHA-256 hash of individual evidence items with source URI, timestamp, and transformation chain
Firm Level: Merkle tree hash aggregating all evidence hashes for a firm, enabling proof of data integrity without downloading entire dataset
Pillar Level: Intermediate hashes combining all firm data for each scoring pillar
Dataset Level: Final SHA-256 hash of complete snapshot with all firms, pillars, and metadata
Signature Verification: ECDSA-secp256k1 cryptographic signatures on all hash levels for non-repudiation and tamper detection

Institutional users can independently verify multi-level integrity using the /api/provenance/verify endpoint with complete transparency into transformation procedures and validation flags.

Governance Framework

Neutrality Charter

GTIXT operates under an explicit neutrality commitment:

⚖️ No Commercial Influence

GTIXT does not accept payments, sponsorships, or incentives from evaluated firms or related parties.

⚙️ No Discretionary Overrides

Scores are deterministic. Identical inputs always produce identical outputs. No manual adjustments permitted.

📋 Deterministic Methodology

All rules are explicit, versioned, and publicly documented. Changes require formal versioning and notice.

👁️ Full Transparency

Scoring rules, data sources, and evidence are public and machine-readable. No proprietary black boxes.

Governance Structure

Governance is enforced through structural separation:

Data Layer (Agent A, B)

Crawl and normalize public evidence. No scoring authority.

Scoring Layer

Apply deterministic methodology. No override capability.

Integrity Layer (Agent C)

Enforce data quality gates. Approve/reject for publication.

Publication Layer

Release immutable snapshots. No modification after publication.

Methodology Evolution

Major versions (v1 → v2): Require 90-day notice, community consultation, and new methodology period.

Minor versions (v1.0 → v1.1): New metrics or data sources, backward compatible, applied prospectively.

All changes are documented in a public changelog and preserved for historical reconstruction.
