Key point

A bot that buys only No in non-sports yes/no markets when the price is at or below a set cap.

Details

Nothing Ever Happens is an async Python bot for Polymarket that scans only standalone non-sports yes/no markets and buys No whenever it is priced at or below a set price.

The core runtime is the nothing_happens strategy, which does the following:

  • Scans markets to find NO entry prices
  • Tracks open positions
  • Provides a dashboard
  • Saves live recovery state when order submission is enabled

The safeguards are also clearly defined.

  • Actual order execution requires BOT_MODE=live, LIVE_TRADING_ENABLED=true, and DRY_RUN=false all at once
  • If any one of these is missing, it runs via PaperExchangeClient
  • In live mode, PRIVATE_KEY, FUNDER_ADDRESS, DATABASE_URL, POLYGON_RPC_URL, and more are additionally required

The configuration and execution flow is simple.

  • config.json holds non-secret runtime settings
  • .env holds secrets and flags
  • A different config file can also be specified via CONFIG_PATH
  • Local execution is done via python -m bot.main

For deployment, it includes a Heroku workflow and helper scripts.

  • Operational scripts such as alive.sh, kill.sh, logs.sh, live_enabled.sh, and live_disabled.sh are provided
  • scripts/db_stats.py, scripts/export_db.py, scripts/wallet_history.py, and scripts/parse_logs.py are used to check the DB, wallet, and logs
  • Tests are run via python -m pytest -q

The project is for entertainment purposes and demonstrates a simple yet practical operational structure for non-sports prediction markets.
