From 5bb220e5712371694e25181f95e11a46f6982776 Mon Sep 17 00:00:00 2001 From: tennisleng Date: Sat, 11 Apr 2026 14:01:19 -0400 Subject: [PATCH] Complete rewrite: institutional-grade triangular arbitrage engine BREAKING: Full ground-up rewrite. Nothing from the old codebase survives. Architecture: - Immutable domain types with Decimal arithmetic (no floats for money) - Exchange adapter pattern (ABC) with Binance implementation - Graph-based triangle discovery (auto-adapts to new listings) - Order-book-aware profit evaluation with 3-leg fee compounding - Sequential tri-leg execution with best-effort rollback - Risk manager with circuit breakers and drawdown guards - Async event loop (asyncio, not threads) - Structured JSON logging via structlog - Pydantic-validated YAML config (fail-fast on invalid config) Testing & CI: - 24 unit tests covering discovery, evaluation, risk, and types - ruff linting (zero warnings) - mypy strict type checking - GitHub Actions CI on Python 3.9+ Removed: - 700-line God class (Model) - Monetization/subscription/payment/license system - ML predictor, dashboard, API server - Hardcoded token lists - Python files as config - Text file logging - Floating-point financial math - Thread-based concurrency - 29 unnecessary dependencies (torch, sklearn, flask, stripe, etc.) --- .github/workflows/ci.yml | 80 +-- .gitignore | 141 +--- ADVANCED_ALGORITHMS.md | 152 ----- MONETIZATION.md | 105 --- MONETIZATION_SUMMARY.md | 138 ---- README.md | 138 ++++ activate_license.py | 51 -- backtest_results.json | 66 -- check_profit.py | 97 --- config.example.yaml | 40 ++ data/secrets.py | 44 -- data/settings.py | 130 ---- data/tokens.py | 32 -

A 64-bit float has ~15 significant digits — enough to silently round away the 1-5 basis point margins this system operates on. Decimal conversion happens at the exchange adapter boundary; internal code never sees floats. + +**Immutable domain types.** All core types (`OrderBook`, `Triangle`, `Opportunity`, `Fill`, `ArbitrageResult`) are frozen dataclasses. This prevents accidental mutation across async tasks and makes the audit trail trivially reproducible. + +**Exchange adapter pattern.** The `ExchangeAdapter` ABC decouples strategy logic from exchange specifics. Swap in a mock adapter and every strategy test runs without network calls. Adding a new exchange means implementing one interface, not modifying strategy code. + +**Graph-based triangle discovery.** Instead of hardcoding token lists, we build an adjacency graph from all trading pairs and enumerate valid 3-cycles. This automatically adapts to new listings and delistings without config changes. + +**Risk manager as a gate, not a modifier.** The risk manager can only reject opportunities — it never modifies them. This makes risk decisions auditable and prevents subtle bugs where risk adjustments interact with execution logic. + +**Structured logging.** Every log entry is a JSON object with `timestamp`, `level`, and `event` fields. No more parsing text files with regex. Pipe to any log aggregation system. + +## Quick Start + +```bash +# Clone and install +git clone https://github.com/tennisleng/Triangular-arbitrage.git +cd Triangular-arbitrage +pip install -e ".[dev]" + +# Configure +cp config.example.yaml config.yaml +# Edit config.yaml with your API keys + +# Run (paper trading by default) +triangular-arb --config config.yaml + +# Run with explicit dry-run +triangular-arb --dry-run +``` + +## Configuration + +Configuration is validated at startup via Pydantic.

Triangle Discovery +On startup, the engine fetches all active trading pairs and builds an adjacency graph. It enumerates all valid 3-node cycles starting from configured base currencies (default: ETH, BTC, USDT). This typically finds 100-500+ triangles depending on the exchange. + +### 2. Continuous Scanning +The async event loop scans each triangle by concurrently fetching all three order books (`asyncio.gather`). For each set of books, the evaluator computes the effective exchange rate around the triangle using actual order book prices (not just top-of-book). + +### 3. Profit Evaluation +Profit is calculated as: +``` +net_rate = (rate_leg1 × rate_leg2 × rate_leg3) × (1 - fee)³ +net_profit_bps = (net_rate - 1) × 10000 +``` +The evaluator uses Decimal arithmetic and accounts for: +- Three legs of trading fees (compounded) +- Bid-ask spread on each leg +- Available liquidity (bottleneck sizing) + +### 4. Risk Gating +Every opportunity passes through the risk manager, which checks: +- Net profit exceeds minimum threshold +- Order books are fresh (not stale) +- Daily drawdown is within limits +- No consecutive loss streak +- Circuit breaker is not tripped + +### 5. Execution +The executor handles tri-leg execution sequentially (output of leg N is input to leg N+1). On any leg failure, it attempts best-effort rollback by reversing completed legs. All fills are recorded for audit trail regardless of outcome. + +## Testing + +```bash +# Run all tests +pytest tests/ -v + +# Run with coverage +pytest tests/ --cov=triangular_arb --cov-report=term-missing + +# Lint +ruff check triangular_arb/ tests/ + +# Type check +mypy triangular_arb/ +``` + +## Project Lineage + +Originally forked from [Cherecho/Triangular-arbitrage](https://github.com/Cherecho/Triangular-arbitrage).
