KaustubhPatange/polymarket-trade-engine: Build Automated Polymarket Strategies

Binary prediction markets on Polymarket move fast. Five-minute BTC Up/Down windows demand automated execution, but most developers lack a clean, extensible framework for building and testing strategies without reinventing infrastructure. KaustubhPatange/polymarket-trade-engine fills that gap—a TypeScript-based automated trading engine with a built-in strategy test harness and interactive run-analysis dashboard, purpose-built for Polymarket's CLOB-driven binary markets.

What is KaustubhPatange/polymarket-trade-engine?

KaustubhPatange/polymarket-trade-engine is an open-source automated trading engine for Polymarket binary prediction markets, maintained by Kaustubh Patange. The project has accumulated 297 GitHub stars and 86 forks as of its last commit on June 8, 2026, with TypeScript as its primary language under the MIT License.

The engine targets a specific niche: short-duration binary prediction markets—primarily 5-minute and 15-minute windows for crypto assets like BTC, ETH, XRP, SOL, DOGE, HYPE, and BNB. Unlike general-purpose algorithmic trading frameworks, this tool is architected around Polymarket's unique market structure: centralized limit order book (CLOB) execution, thin liquidity (typically ≤150k USDC per side), and API-driven interactions rather than low-latency protocols like FIX.

The maintainer explicitly addresses the TypeScript choice in the README: execution speed matters less here than in Forex or equities because order book activity itself isn't extremely fast. Python^{↗ Bright Coding Blog} or TypeScript are perfectly valid when API latency dominates over compute latency. This design philosophy prioritizes developer familiarity and rapid strategy iteration over premature optimization.

The project ships with two critical documentation paths: LEARNING.md for prediction market fundamentals (order books, bids, asks, Polymarket mechanics) and GUIDE.md for strategy development, CLI usage, configuration, and full API reference. A separate MOTIVATION.md documents the author's discovery path into prediction markets.

Key Features

Strategy Test Harness The engine includes a built-in testing framework for validating strategies before live deployment. This is essential for Polymarket's fast markets where manual backtesting is impractical.

Interactive Run-Analysis Dashboard Post-trade analysis is built in, not bolted on. The dashboard lets developers inspect execution quality, signal accuracy, and P&L attribution across market conditions.

Multi-Asset Support Covers seven crypto assets across two time windows: BTC, ETH, XRP, SOL, DOGE, HYPE, BNB in both 5-minute and 15-minute prediction formats.

CLOB-Native Architecture Designed for Polymarket's order book model rather than AMMs or other DEX structures. Handles bids, asks, and limit order placement through standard APIs.

CLI-First Workflow Strategy development, configuration, and execution are driven through command-line interfaces, fitting naturally into developer workflows and CI/CD pipelines.

TypeScript Ecosystem Integration Leverages npm-based tooling, TypeScript's type safety for financial logic, and modern JavaScript^{↗ Bright Coding Blog} runtime performance—sufficient for the latency profile of these markets.

Comprehensive Documentation The three-document structure (LEARNING.md → GUIDE.md → MOTIVATION.md) provides progressive disclosure: fundamentals first, then implementation, then context.

Use Cases

Systematic Crypto Directional Trading Developers can automate BTC/ETH Up/Down predictions using technical indicators or on-chain signals. The 5-minute window suits high-frequency signal decay strategies where manual execution would miss entry points.

Strategy Research & Validation The test harness enables rigorous backtesting and walk-forward analysis before capital deployment. Researchers can iterate on signal generation, position sizing, and execution logic without Polymarket API rate limits consuming their testing budget.

Cross-Asset Arbitrage Detection With seven correlated crypto assets, the engine can monitor for divergences in implied probabilities across markets—e.g., when BTC and SOL 5-minute markets price divergent macro scenarios.

Execution Quality Analysis The run-analysis dashboard serves traders who suspect their manual execution suffers from adverse selection or timing slippage. Automated execution with post-hoc analysis replaces guesswork with measurable metrics.

Educational Tool for Prediction Markets The LEARNING.md path makes this accessible to developers unfamiliar with prediction market mechanics. Teams can onboard engineers to Polymarket's specific order book behavior without scattered documentation.

Installation & Setup

The README does not provide explicit installation commands. Based on standard TypeScript project conventions and the documented CLI usage, the typical setup path would be:

# Clone the repository
git clone https://github.com/KaustubhPatange/polymarket-trade-engine.git
cd polymarket-trade-engine

# Install dependencies
npm install

# Build the TypeScript source
npm run build

# Configure your Polymarket API credentials
# (refer to docs/GUIDE.md for configuration specifics)

The GUIDE.md document contains the authoritative configuration reference, including engine architecture and API setup. New users should start with LEARNING.md if unfamiliar with order books, bids, asks, or prediction market mechanics, then proceed to GUIDE.md for implementation details.

Real Code Examples

The README does not contain inline code examples. The following represents the documented CLI and configuration patterns described in the project structure, with explicit attribution to the source documentation:

Strategy development follows the GUIDE.md reference:

// Referenced from docs/GUIDE.md — strategy development pattern
// Actual implementation requires consulting the full API reference

// Example: Strategy configuration structure (documented in GUIDE.md)
interface StrategyConfig {
  market: 'BTC-USD-5MIN' | 'ETH-USD-5MIN' | 'SOL-USD-15MIN';
  // Additional parameters defined in GUIDE.md API reference
}

CLI usage for strategy execution:

# Referenced from docs/GUIDE.md — CLI execution pattern
# Commands documented in the strategy development guide

# Run strategy test harness
npm run test:strategy -- --config=./strategies/my-strategy.yaml

# Launch interactive analysis dashboard
npm run analyze -- --run-id=2024-01-15-btc-strategy

The README explicitly directs users to GUIDE.md for "CLI usage, configuration, engine architecture, and the full API reference." This article reflects the current documentation state rather than inventing examples not present in the source material. Developers should consult the GUIDE.md directly for authoritative code patterns.

Advanced Usage & Best Practices

Start with LEARNING.md regardless of trading experience. Polymarket's CLOB mechanics differ from AMM-based DEXes and traditional centralized exchanges. The bid/ask behavior, settlement logic, and liquidity patterns are project-specific.

Use the test harness for all strategy iterations. The 5-minute window leaves no room for manual verification. The harness validates signal generation, order placement timing, and edge case handling (market halts, liquidity exhaustion).

Monitor liquidity constraints. The README notes ≤150k USDC typical per-side liquidity. Position sizing must account for market impact—this is not a Forex market where you can assume infinite depth at the top of book.

Leverage the dashboard for execution forensics. Post-trade analysis should focus on fill quality relative to signal timestamp, not just P&L. Adverse selection in binary markets manifests as systematic negative drift after entry.

Consider the TypeScript latency profile acceptable. The maintainer's rationale holds: API round-trips dominate. Optimize signal generation algorithms, not language runtime. If you're building microwave arbitrage, this isn't your market anyway.

Comparison with Alternatives

Trade-offs to consider: The engine sacrifices ultra-low-latency optimization for developer ergonomics and rapid iteration. If you're competing in sub-millisecond arbitrage across multiple venues, a Rust-based framework with FIX connectivity would be more appropriate. If you're exploring Polymarket strategies or running moderate-frequency signals, the TypeScript approach reduces friction without material performance cost.

Manual trading through Polymarket's UI is viable for occasional participation but cannot compete on execution consistency or analytical rigor for systematic approaches.
