🎯 Project Scope

VenueWatch is an infrastructure intelligence tool, strictly designed for quantitative research, not live trading. It does not perform order routing.

It evaluates venue quality through the lens of:

• Canonical Schema Isolation: Public Exchange JSON payloads are strictly bounded and transformed into normalized Parquet structs at the adapter layer.
• Robust Anomaly Detection: A lightning-fast 2-Tier Statistical Framework (Deterministic Rule Engine → Median Absolute Deviation (MAD)) natively integrated into the hot-path asynchronous loop.
• Institutional Realism: Built-in NetworkRTTMonitor and CausalImpactAnalyzer accurately separate true matching-engine latency from internet routing delays, and calculate empirical market-impact execution profiles without synthetic data bias.

🏗️ System Architecture

The pipeline is completely asynchronous and mathematically optimized to process millions of ticks per second on a single thread.

✨ Key Features

• Synthetic Fault Injection: Benchmarks system resilience by natively injecting packet delays, missing events, and duplicate sequences directly into the canonical stream.
• Order-Size Sensitivity: Generates dynamic execution quality curves ($10K to $1M), proving that venue rankings shift wildly based on order size depth requirements.
• Min-Max Score Normalization: Replaces naive ordinal rankings with mathematically rigorous Min-Max interval scaling to preserve the actual spread and latency magnitude differences.
• Weight Sensitivity Analysis: Evaluates rank stability across thousands of randomized Dirichlet weight perturbations to calculate the exact probability of venue dominance.

⚡ Quantitative Benchmarks

The following metrics were calculated deterministically by processing 100,000 real historical ticks (BTCUSDT) and live Order Book fixtures through the core AsyncEventPipeline:

Subsystem	Throughput / Capacity	Implementation Detail
Parsing & Validation	> 134,300 events/sec	Pydantic strict bounds checking
Analysis Pipeline	> 3.40 Million events/sec	Health and Market Quality routing
MAD Anomaly Engine	~ 19,800 events/sec	Rolling absolute median dev array traversal
Storage IO (Parquet)	~ 125,000 events/sec	pyarrow batch writing with ZSTD compression
Baseline Latency	~ 0.29 µs / event	Subtracted active TCP handshake RTT from processing time

Note

All benchmarks were conducted using real market data and strict chronological sequencing. Zero synthetic execution data is used for ranking.
