CLOB Microstructure Scanner

Structural alpha from Polymarket order book analysis. Nobody else on Simmer does this.

What It Does

Pulls raw order book data from Polymarket's CLOB API and scores each market on four

microstructure dimensions:

Each dimension scores 0-25, combined into a 0-100 inefficiency score.

Signals

• ENTRY_OK — Normal conditions, standard sizing
• REDUCE_SIZE — Elevated microstructure risk, cut position size
• SKIP — Too dangerous, stay out
• MEAN_REVERT — Fake breakout detected, fade the move

The bot only trades on MEAN_REVERT signals, fading fake breakouts via SimmerClient.

Configuration

• Runs every 5 minutes via cron
• Defaults to dry-run; pass --live for real execution
• Requires SIMMER_API_KEY environment variable

Usage

# Dry run (default)
python clob_microstructure.py

# Live trading
python clob_microstructure.py --live

# Quiet mode for cron
python clob_microstructure.py --live --quiet
