Aster Skill

What This Skill Does

The Aster Skill is an autonomous trading agent designed to bridge the gap between real-time crypto sentiment analysis and automated order execution. By leveraging the OpenNews MCP, the skill actively monitors crypto-native news streams and Twitter feeds to identify high-impact market events. It filters for assets including BTC, ETH, SOL, and BNB, subjecting each headline to an LLM-powered sentiment analysis engine.

This agent does not just read news; it evaluates the credibility, timeliness, and market sensitivity of information. Only when a signal reaches a confidence threshold of 0.70 and exhibits at least 'medium' signal strength does the agent trigger an order. It manages the full lifecycle of a trade, including setting 5x leverage, calculating stop-loss and take-profit parameters, and enforcing a per-coin 30-minute cooldown to prevent over-trading in volatile environments.

Installation

To integrate this skill, ensure you have the OpenClaw agent runtime installed. Run the following commands in your terminal:

1. Install the news monitoring dependency: npx clawhub install opennews-mcp
2. Install the core trading agent: clawhub install openclaw/skills/skills/asterskillagent/aster-skill

Once installed, configure your API credentials within the agent settings to allow the skill to interact with your preferred exchange via the Aster client.

Use Cases

• Automated Scalping: Respond instantly to breaking news announcements (e.g., regulatory shifts, ETF approvals, or protocol upgrades) before the broader market reacts.
• Sentiment-Driven Hedging: Maintain an automated baseline for your portfolio, allowing the agent to place short orders when negative market sentiment spikes.
• News-Filtered Trading: Filter out noise and only execute trades when major, high-credibility news sources report on specific assets.

Example Prompts

1. "Aster, monitor the market and open a long position on SOL if there is strong bullish news confidence above 0.8."
2. "Show me the current sentiment analysis for ETH and tell me if the agent is planning any trade actions."
3. "Aster, pause all trading activity until I confirm I want to resume, but keep the news feed running."

Tips & Limitations

• Market Volatility: Always set your risk parameters appropriately. The 5x leverage is high; ensure you have sufficient collateral to withstand liquidations.
• Cooldown Strategy: The default 30-minute cooldown is a safeguard. Do not lower this without extensive backtesting, as it may lead to execution loops during high-news-frequency periods.
• Confidence Thresholds: While the agent defaults to 0.70 confidence, you can tune this higher if you prefer fewer, higher-conviction trades.
