Core Components of a News-Driven Polymarket Bot
How News-Driven Polymarket Trading Bots Work: 5-Layer Architecture
Creating a news-driven bot involves five key layers: Data Layer (for data collection), Strategy Layer (to generate actionable signals), Execution Layer (to manage orders), Risk Layer (to control exposure), and Monitoring Layer (to handle logging and alerts). Each layer is crucial for transforming breaking news into profitable trades in mere milliseconds.
Polymarket API: Platform Connection
Polymarket’s hybrid system uses specialized interfaces for seamless communication. The Gamma API focuses on market discovery and metadata – helpful for linking news events to specific tradable markets. The CLOB API is the trading engine, offering real-time prices, order book depth, and order placement. For latency-critical tasks, the WebSocket API delivers instant updates on prices and order fills.
Authentication relies on HMAC-SHA256 signatures, requiring an API key, secret, and a timestamp that expires after 30 seconds. Official SDKs are available for TypeScript (@polymarket/clob-client) and Python (py-clob-client) to streamline integration. Be aware of strict rate limits: public endpoints allow 100 requests per minute per IP, while trading endpoints cap at 60 orders per minute per API key. Use the createOrDeriveApiKey() method in the SDK to generate L2 credentials directly from your wallet signer. For real-time data, connect to the CLOB WebSocket for order book updates with ~100ms latency or the Real-Time Data Socket (RTDS) for broader market and sentiment insights.
| API Component | Purpose | Endpoint |
|---|---|---|
| Gamma API | Market discovery & metadata | https://gamma-api.polymarket.com |
| CLOB API | Trading & order book data | https://clob.polymarket.com |
| WebSocket | Real-time data streaming | wss://ws-subscriptions-clob.polymarket.com |
This API setup forms a solid foundation for integrating real-time news feeds.
News Ingestion and Processing
News feeds are the lifeblood of a news-driven bot, providing the signals needed for quick trading decisions. Bots connect to news APIs and web search platforms, often leveraging vector databases to enhance contextual understanding. The RTDS includes a "Comments" topic, streaming user reactions and comments – useful for sentiment analysis and detecting social signals. Natural Language Processing (NLP) tools analyze sentiment or identify specific triggers, like election results or economic data, to create buy/sell signals.
To minimize latency in execution price calculations, keep a local copy of the order book and apply incremental updates using the price_change message type. During periods of low news activity, maintain WebSocket connections with heartbeat messages – send a "PING" every 10 seconds for the CLOB WebSocket and every 5 seconds for the RTDS. If the connection drops, ensure your bot automatically re-subscribes to all relevant market topics to avoid missing critical updates.
Strategy Logic and Risk Management
Effective strategy logic must include strict safeguards to protect capital. For example, limit any single position to no more than 5% of the portfolio. Implement stop-loss rules and emergency shutdowns to pause trading during extreme market volatility or API outages. Keep an eye on order book imbalances – a ratio above 0.6 often signals buying pressure – and monitor large trades ("whale" transactions) to gauge market sentiment.
"A well-designed bot can analyze market conditions, calculate optimal position sizes, and execute trades in milliseconds – far faster than any human trader." – AL, Founder of PolyTrack
If the API returns a 429 status code (indicating rate limits are exceeded), use exponential backoff to retry requests at progressively longer intervals. Before risking actual USDC, validate your bot’s performance with paper trading simulations to test its reaction to news signals. Always store sensitive credentials like POLY_API_KEY and POLY_SIGNATURE securely in environment variables, avoiding hardcoding them into scripts.
How to Build and Deploy a News-Driven Polymarket Bot
Setting Up the Development Environment
To get started, you’ll need Python 3.9.10 or later. Install the required libraries using this command: pip install py-clob-client web3==6.14.0 python-dotenv. Be sure to stick with the specific version of web3 (6.14.0) to avoid any compatibility issues.
You’ll also need an Ethereum-compatible wallet with USDC on Polygon. To export your private key, log in to Polymarket, go to "Cash", click the three-dot menu, and select "Export Private Key." Remove the ‘0x’ prefix before saving it in your .env file. Use the create_or_derive_api_creds() method from py-clob-client to generate your API Key, Secret, and Passphrase. These credentials are derived from your private key and only need to be created once.
When setting up the client, you’ll need to choose the signature_type that matches your wallet:
-
0for standard Ethereum wallets like MetaMask -
1for Polymarket email/Magic wallets -
2for wallets like Gnosis Safe or browser-based wallets
The default CLOB host is https://clob.polymarket.com, and the Chain ID for Polygon Mainnet is 137.
| Wallet Type | Signature Type ID | Description |
|---|---|---|
| EOA | 0 | Standard Ethereum wallet (e.g., MetaMask) |
| Custom Proxy | 1 | Polymarket email/Magic Link users |
| Gnosis Safe | 2 | Injected wallets (e.g., Coinbase Wallet) |
Integrating News Feeds and Polymarket APIs
To connect news feeds with Polymarket trading, you’ll use three APIs: the Gamma API for finding markets, the CLOB API for placing orders, and WebSockets for real-time updates. Start by querying the Gamma API’s /events or /markets endpoints. Use keywords from news headlines to match them with market "slugs" or "questions." Filter with active=true&closed=false to focus only on live, tradable markets.
Authentication works on two levels:
- L1: Uses your private key to sign EIP-712 messages.
- L2: Uses your API Key, Secret, and Passphrase for faster HMAC-SHA256 signing. These requests expire after 30 seconds for added security.
Each market has two clobTokenIds – one for "Yes" and one for "No." These IDs are critical for retrieving prices and placing trades.
For real-time updates, WebSocket connections are much faster (~100ms latency) compared to REST polling (~1 second). Use the tenacity library for exponential backoff to handle rate limit errors like HTTP 429. Public endpoints allow up to 100 requests per minute per IP, while authenticated endpoints are capped at 60 orders per minute per API key.
| API Component | Latency | Primary Use Case |
|---|---|---|
| WebSocket | ~100ms | Real-time updates, order book changes, trade alerts |
| Gamma API | ~1s | Market discovery, metadata, and resolution info |
| CLOB API | Variable | Core trading operations like placing and managing orders |
Once you’ve tested the API connections locally and confirmed everything works, you’re ready to deploy your bot.
Deploying on QuantVPS for Low-Latency Execution
After testing locally, deploy your bot on a VPS to ensure it runs 24/7 with consistent performance. QuantVPS offers various plans:
- VPS Lite: $59.99/month ($41.99/month billed annually) with 4 cores and 8GB RAM.
- VPS Pro: $99.99/month ($69.99/month billed annually) with 6 cores, 16GB RAM, and 150GB NVMe storage. This plan is ideal for bots handling 3–5 markets.
- Dedicated Server: $299.99/month ($209.99/month billed annually) with 16+ dedicated cores and 128GB RAM.
For instant updates, use WebSocket connections (CLOB WebSocket or RTDS) instead of REST polling. Ensure mandatory heartbeat signals are sent to keep connections alive – CLOB WebSocket requires a "PING" every 10 seconds, and RTDS requires one every 5 seconds. To handle connection drops, implement reconnection logic with exponential backoff and jitter.
Security Tip: Never hardcode sensitive information like API keys or private keys. Use environment variables or a secret management tool on your VPS. Set up real-time alerts via Discord or Telegram to notify you of disconnections, risk breaches, or API errors. Include an emergency shutdown mechanism to stop trading during extreme volatility or technical issues.
Finally, check that your funder address (proxy wallet) has enough USDC for buy orders and sufficient outcome tokens for sell orders to avoid execution rejections.

QuantVPS includes DDoS protection and advanced firewall rules to defend against external threats. You can further secure your setup by enabling IP whitelisting, allowing API access only from your VPS server. Polymarket’s API adds another layer of security with HMAC-SHA256 signature authentication and timestamps that expire after 30 seconds, preventing replay attacks. Regularly rotating your API credentials is a good practice to reduce the likelihood of compromise.
"Protect your trading capital and sensitive data with our multi-layered security protocols… We proactively defend against threats like DDoS attacks and unauthorized access attempts." – QuantVPS
To safeguard your trading algorithms and historical data, set up enterprise-grade backups. For added security, transfer profits from your bot-connected "hot" wallet to a hardware wallet. Monitor your bot’s performance remotely using secure Remote Desktop (RDP), allowing you to tweak parameters in real time from anywhere. Additionally, implement rate limit handling with exponential backoff to manage HTTP 429 errors. Keep in mind that Polymarket’s API caps authenticated endpoints at 60 orders per minute per API key and public endpoints at 100 requests per minute per IP.
Scaling for Multi-Market or High-Volume Trading
Once speed and security are in place, scaling your trading operations becomes the next focus. Whether you’re expanding to multiple markets or handling higher volumes, your infrastructure must keep up. QuantVPS offers tailored solutions for scaling, such as the VPS Pro plan ($99.99/month or $69.99/month annually), which includes 6 cores and 16GB RAM – ideal for managing 3–5 markets.
