Description
Momentum-based trading skill for Simmer prediction markets. Detects probability momentum and divergence to generate YES/NO trades on Polymarket. Remixable —...
Usage Guidance
This skill appears to do what it says, but consider these practical safety steps before installing:
- Limit the SIMMER_API_KEY permissions if possible (use a key that can trade but with appropriate limits/quotas).
- Confirm that the simmer-sdk package is the official SDK you expect (review source/package metadata) before installing.
- The manifest schedules runs every 15 minutes; ensure your deployment won't pass --live automatically. By default the script is a dry-run and only executes real trades when run with --live.
- Review the calculate_signal() function if you or contributors remix it — adding external data sources (Twitter, Reddit, external ML services) can introduce new network endpoints and data-handling risks.
- Be aware of trading risk and compliance/regulatory considerations for automated market activity.
If you want higher assurance, ask the author for a link to the simmer-sdk package source and confirmation that automated runs will never be started with --live without explicit operator action.
Capability Analysis
Type: OpenClaw Skill
Name: simmer-momentum-trader
Version: 1.0.0
The skill is a legitimate momentum-based trading bot for Simmer prediction markets. It uses the 'simmer-sdk' to monitor markets and execute trades based on probability divergence, following best practices such as using environment variables for API keys and defaulting to a dry-run mode. No indicators of data exfiltration, malicious execution, or prompt injection were found in simmer_momentum_trader.py or SKILL.md.
Capability Assessment
Purpose & Capability
Name/description match the code and SKILL.md: it monitors Simmer markets and can place trades. Declared requirement (SIMMER_API_KEY) and the pip dependency (simmer-sdk) are appropriate for a Simmer/Polymarket integration.
Instruction Scope
Runtime instructions and the Python entrypoint only read the declared env vars (SIMMER_API_KEY, DIVERGENCE_THRESHOLD, TRADE_AMOUNT, MARKET_IDS) and call the Simmer SDK. The SKILL.md does not ask the agent to read unrelated files or exfiltrate data. Trade execution requires an explicit --live flag (defaults to dry-run).
Install Mechanism
No arbitrary downloads or extract steps. The manifest lists a pip dependency (simmer-sdk), which is proportional to the stated purpose. No installer URLs or unusual install locations are present.
Credentials
Only one required secret (SIMMER_API_KEY) is declared and used to instantiate the SimmerClient. Other env vars are configuration (threshold, amount, market IDs). No unrelated credentials or system config paths are requested.
Persistence & Privilege
The manifest includes a cron entry (*/15 * * * *) and automaton.managed:true, so the skill is intended to run periodically. It does not set always:true. Ensure scheduled runs are acceptable — by default the script is a dry-run, but an automated environment could be configured to run with --live, enabling autonomous real trades.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install simmer-momentum-trader - After installation, invoke the skill by name or use
/simmer-momentum-trader - Provide required inputs per the skill's parameter spec and get structured output
Version History
v1.0.0
Initial release of the Simmer Momentum Trader skill:
- Trades YES/NO on Polymarket using a probability momentum and divergence signal.
- Configurable divergence threshold and trade amount via environment variables.
- Monitors Simmer watchlist markets and executes trades when signal criteria are met.
- Designed as a remixable template: swap in alternative signals (volume, sentiment, ML predictions).
- Dry-run mode enabled by default, with safeguards for live-trading.
- Handles all plumbing — market access, trade execution, error handling — so you can focus on signal design.
