# DeltaTrace

Deterministic Replayable Latency & Compliance Tracing for Live Market-Execution Pipelines.

A cross-layer traceability toolkit for high-frequency trading systems that enables deterministic replay of order lifecycles, end-to-end latency accounting, governance-ready audit trails, and vendor-agnostic adapters.

## Core Components

- **Event Graph**: Models market events (ticks, signals, orders, fills, risk checks) as a DAG with causal edges and latency budgets
- **Replay Engine**: Deterministically replays captured event streams to reproduce decision paths
- **Audit Log**: Crypto-signed, tamper-evident governance log for regulatory reviews
- **Adapters**: Pluggable adapters for FIX feeds and exchange gateways

## Quick Start

```bash
pip install -r requirements.txt
python -m deltatrace.demo
```

## Testing

```bash
./test.sh
```
