Polymarket Trading Bot

An automated trading bot for Polymarket's 5-minute BTC prediction markets.

Configuration

The bot requires the following environment variables:

Required Variables

• PRIVATE_KEY: Your Ethereum private key (with 0x prefix)
• FUNDER_ADDRESS: Your wallet address that holds funds

Optional Variables

• SIGNATURE_TYPE: Signature type for order signing (default: 0)
  • 0: EOA (Externally Owned Account) - Standard Ethereum wallet
  • 1: POLY_PROXY - Polymarket proxy wallet
  • 2: POLY_GNOSIS_SAFE - Gnosis Safe wallet

Fixing Signature Errors

If you encounter PolyApiException[status_code=400, error_message={'error': 'invalid signature'}], this typically means:

1. Using a Polymarket Proxy Wallet: Set SIGNATURE_TYPE=1

   export SIGNATURE_TYPE=1

2. Using a Gnosis Safe: Set SIGNATURE_TYPE=2

   export SIGNATURE_TYPE=2

3. Address Mismatch: Ensure your FUNDER_ADDRESS matches the address associated with your PRIVATE_KEY

Usage

# Set environment variables
export PRIVATE_KEY="0x..."
export FUNDER_ADDRESS="0x..."
export SIGNATURE_TYPE=1  # If using Polymarket proxy wallet

# Run the bot
python3 polytrader.py

How It Works

The bot:

1. Monitors 5-minute BTC prediction markets on Polymarket
2. Compares current BTC price with the market start price
3. Places trades when price change exceeds the threshold (±0.02%)
4. Uses Martingale strategy for position sizing after losses
