jgrusewski 5b9995c6f5 chore(services): drop unused declared deps (cargo-machete cleanup)
Remove dependencies declared in 5 service Cargo.toml files that no
source code in those services references (verified by grepping for
use statements). Reduces dep-graph fan-out and unnecessary recompiles.

  services/api/Cargo.toml             −16 deps  (async-trait, bytes,
                                                 const-oid, hdrhistogram,
                                                 hex, http-body, hyper,
                                                 hyper-util, num-traits,
                                                 rust_decimal, tokio-stream,
                                                 tower-layer, tower-service,
                                                 tracing-subscriber,
                                                 trading_engine, zeroize.
                                                 + json feature added to
                                                 reqwest since trading_engine
                                                 was enabling it transitively)
  services/trading_service/Cargo.toml −11 deps
  services/backtesting_service/Cargo.toml −17 deps
  services/trading_agent_service/Cargo.toml −6 deps
  services/ml_training_service/Cargo.toml −4 deps

False positives kept (cargo-machete misses these because they're only
referenced in tonic-generated proto code, not in hand-written src):
  - prost            (`::prost::Message` derive in build.rs-generated code)
  - tonic-prost      (`tonic_prost::ProstCodec::default()` in generated tonic
                     clients/servers)

cargo check --workspace passes.

Foxhunt

Production HFT trading system in Rust.

Architecture

The workspace contains 32 crates organized as follows:

Core Libraries (16)

Crate Purpose
trading_engine Order processing, FIX 4.4, IB TWS, SIMD, RDTSC timing
risk VaR, Kelly, circuit breakers, kill switches, compliance
risk-data Risk data types and shared structures
trading-data Trading data types
ml DQN Rainbow, PPO, TFT, Mamba2, ensemble inference
ml-data ML data types and feature definitions
data Market data ingestion and storage
backtesting Replay engine, strategy tester
adaptive-strategy Ensemble execution, microstructure analysis
common Shared types, resilience, error handling
storage S3 and local model storage
model_loader Model serialization and loading
market-data Market data feed handlers
database PostgreSQL access layer (SQLx)
config Configuration management
tli CLI commands and tooling

Services (8)

Service Purpose
backtesting_service gRPC backtesting service
broker_gateway_service FIX routing, broker connectivity
trading_service Core trading operations
ml_training_service Model training orchestration
data_acquisition_service Market data acquisition
trading_agent_service Autonomous trading agents
api_gateway gRPC API gateway with auth
web-gateway Axum REST + WebSocket gateway

Frontend

web-dashboard/ -- React 19 + TypeScript + Vite + TradingView charts.

Building

# Check compilation (no PostgreSQL required)
SQLX_OFFLINE=true cargo check --workspace

# Run tests for a specific crate
SQLX_OFFLINE=true cargo test -p <crate> --lib

# Clippy
SQLX_OFFLINE=true cargo clippy --workspace

ML Models

Four production model architectures on Candle v0.9.1 with CUDA:

  • DQN Rainbow -- Deep Q-Network with prioritized replay, dueling heads, noisy nets
  • PPO -- Proximal Policy Optimization with GAE and LSTM policies
  • TFT -- Temporal Fusion Transformer for multi-horizon forecasting
  • Mamba2 -- State space model for sequence prediction

Each model has a standalone trainer and a UnifiedTrainable adapter for the hyperopt pipeline.

Infrastructure

  • Git: Gitea at git.fxhnt.ai (Tailscale-only), Scaleway DEV1-S
  • Observability: OpenTelemetry OTLP (env OTEL_EXPORTER_OTLP_ENDPOINT)
  • Database: PostgreSQL with SQLx offline mode for CI
