Manual Trade Placement

Place trades on Polymarket by telling your AI agent what to bet on. Supports instant FAK fills and GTC limit orders. Works with Simmer market IDs or full Polymarket event URLs.

Usage

Tell your agent:

"Buy YES $10 on [Polymarket URL or market ID]" "Place a GTC limit NO $20 at 0.35 on [market]"

Or run directly:

# FAK — instant fill at best ask price (default)
python3 manual_trade.py --market <market_id_or_url> --side YES --amount 10

# GTC — limit order, sits on book until filled
python3 manual_trade.py --market <market_id_or_url> --side NO --amount 20 --order GTC --price 0.35

# Full Polymarket URL — auto-imports and trades
python3 manual_trade.py \
  --market https://polymarket.com/event/spacex-starship-flight-test-12/will-the-chopsticks-catch-spacex-starship-flight-test-12-superheavy-booster \
  --side YES --amount 10

# Dry run (preview without placing)
python3 manual_trade.py --market <id> --side YES --amount 10 --dry-run

Order Types

Arguments

How it Works

1. Market resolution — if you pass a Polymarket URL, it auto-imports via Simmer's import API and resolves to the correct market
2. Price discovery — fetches live CLOB order book, uses best ask + 0.01 for FAK to guarantee fill
3. Order placement — signs and submits via simmer-sdk with your wallet key
4. Confirmation — reports shares filled, cost, and trade ID

Requirements

• SIMMER_API_KEY — your Simmer API key
• WALLET_PRIVATE_KEY — your Polymarket wallet private key (for on-chain signing)
• simmer-sdk >= 0.8.32

Built for Simmer — the AI trading agent platform for Polymarket and Kalshi.
