Polymarket Trading Bot (TypeScript) - RSI, MACD, Momentum

A configurable Polymarket trading bot for 15m Up/Down markets using RSI, MACD, and Momentum signals.

If you are searching for a Polymarket Arbitrage bot, this repo is a signal-based trading bot (not a true cross-market arbitrage engine), but it is a practical base to build arbitrage logic on top of the Polymarket CLOB and Gamma APIs.

What This Bot Does

• Discovers active ETH/BTC Polymarket markets from Gamma API
• Pulls token prices from CLOB API
• Computes rolling RSI / MACD / Momentum indicators
• Produces BuyUp / BuyDown / NoAction decisions
• Runs in simulation mode with detailed logs
• Supports CLOB authentication and order helper methods for extension

Current Status

• --simulation: fully supported and continuously logs signals/actions
• --live: currently starts the same loop as simulation (real order execution is scaffolded but not wired into the main loop yet)

How To Extend Into a Real Arbitrage Bot

To convert this into a stronger Polymarket Arbitrage bot, add:

• Cross-market price spread detection (related markets / outcome parity)
• Multi-leg execution with slippage controls
• Position netting and inventory risk checks
• Latency-aware quoting and cancellation logic
• PnL accounting per strategy and market
