Option Flow Intelligence Skill

Query the OptionWhales Pro API for real-time institutional option flow analysis:

• Intent Momentum — clustered option trades scored for directional intent, coherence, and momentum
• Abnormal Trades — large or unusual option activity flagged in real-time

Free tier available! Sign up at https://www.optionwhales.io to get a free API key instantly — no credit card required. Free keys return the top 3 tickers and last 5 abnormal trades, enough to evaluate the data and build integrations. Upgrade to Pro for full access.

When to Use

✅ USE this skill when:

• "What's the option flow on AAPL today?"
• "Show me unusual options activity"
• "What are institutions buying?"
• "Is there bullish or bearish momentum in TSLA?"
• "Show me the top momentum tickers"

When NOT to Use

❌ DON'T use this skill when:

• Stock price quotes only → use a stock/market data skill
• Historical stock charts → use a charting skill
• GEX / gamma exposure queries → not exposed via Pro API
• Open interest time series → not exposed via Pro API
• Options pricing or Greeks calculation → use a quant tool
• News/earnings analysis → use a news skill
• Crypto or forex → this is US equity options only

Interpreting Results

Intent Types

Direction Bias

• bullish: Net positive delta flow
• bearish: Net negative delta flow
• neutral: Delta share below 15% of total flow

Confidence Score

0–1 scale combining flow coherence (how aligned the trades are) and strength (total dollar Greek magnitude). Above 0.7 is high conviction.

Momentum

• momentum_fast (α=0.35): responsive to recent flow changes
• momentum_slow (α=0.15): trend-smoothed
• Positive = bullish acceleration, negative = bearish acceleration
