Breaking News Event Trader

Comprehensive breaking news monitor that trades Polymarket markets on high-impact events.

What It Does

Continuously polls 20+ premium news RSS feeds, pre-filters stories with fast keyword

matching, then matches relevant stories to active Polymarket markets. When a breaking

story has estimated price impact >12%, generates a trade signal.

News Sources

Pre-Filter System

Two-stage filtering for speed:

1. Fast reject — Skip stories with common noise keywords (opinion, podcast, review)
2. Fast accept — Prioritize stories with high-signal keywords (breaking, passes,

signs, ruling, indicted, default, crash, surge)

Only stories passing pre-filter get matched against Polymarket markets.

Impact Estimation

Stories are scored on:

• Source credibility tier (wire services > financial > blogs)
• Keyword signal strength
• Headline match quality to market question
• Recency (exponential decay over 30 minutes)

Requirements

pip dependencies: simmer-sdk, requests, feedparser

Environment variables:

• SIMMER_API_KEY (required) - get from simmer.markets/dashboard
