simmer-mertsniper

What This Skill Does

The simmer-mertsniper skill is an automated trading agent designed for the Polymarket platform, specifically focused on the 'Mert Sniper' strategy. This strategy targets prediction markets that are nearing their resolution deadline where the probability odds have become heavily skewed. By scanning for markets with strong splits (e.g., 60/40 or greater) that are set to close within a specific, short-term window, the skill allows users to capture final-minute conviction value. It operates by fetching market data from the Simmer API, applying user-defined filters, and executing trades directly via the OpenClaw environment.

Installation

To integrate this skill into your OpenClaw agent, execute the following command in your terminal:

clawhub install openclaw/skills/skills/adlai88/mertsniper

After installation, you must obtain an API key from simmer.markets and set it as an environment variable SIMMER_API_KEY. You may also define default settings in your configuration file to align with your personal risk tolerance, such as the maximum bet per trade or the default expiry window for scanning candidate markets.

Use Cases

1. High-Frequency Conviction Trading: Users who want to capitalize on information asymmetry in the final minutes of a market cycle without manual monitoring.
2. Topic-Specific Arbitrage: Traders focusing on specific niches like 'Crypto' or 'Politics' can use the --filter command to ignore noise and focus on markets they understand best.
3. Automated Risk Management: By setting a hard cap on individual bets and using the smart-sizing feature, the skill ensures that no single market event can jeopardize the user's entire portfolio balance.

Example Prompts

1. 'Run the simmer-mertsniper and execute trades on any SOL markets closing in the next 3 minutes if the split is better than 65/35.'
2. 'OpenClaw, perform a dry run of the Mert Sniper strategy with a max bet of $25 per market and show me the potential positions.'
3. 'Check my current portfolio and then trigger the sniper with live trading enabled, using smart sizing to allocate funds based on my balance.'

Tips & Limitations

• Dry-Run First: Always execute the script without the --live flag initially. This allows you to verify that your filters are working as intended without risking real USDC.
• Network Latency: Since this is a sniping strategy, speed is critical. Ensure your environment has a stable connection to the Simmer API to avoid execution slippage.
• Safeguards: Never disable the --no-safeguards flag unless you are testing in a sandbox environment; the built-in limits are designed to prevent catastrophic loss due to unexpected market volatility or logic errors.
