Frequently Asked Questions

Everything you need to know about AI-Based Unusual Activity detection

We use 10 different detection algorithms that analyze trades against historical patterns. A trade is flagged as unusual when it shows significant deviation from expected behavior in metrics like volume (vs 5-day average), premium size, moneyness, time to expiration, and order aggressiveness. Each algorithm contributes to an overall Unusual Score (0-100), with scores above 70 indicating highly unusual activity that warrants attention.

The Unusual Score is a weighted composite of all 10 detection algorithms, scaled from 0-100. Each algorithm evaluates different aspects of the trade (volume spike, size vs OI, moneyness, etc.) and contributes to the final score. Scores 70-85 indicate unusual activity, while 85-100 represent extremely unusual trades that often precede significant price movements. The scoring system adapts to market volatility and historical patterns for each underlying.

Our algorithms are validated against 15+ years of historical data and tuned to minimize false positives while capturing meaningful signals. While no system is perfect, our multi-algorithm approach provides robust detection by requiring multiple indicators to align before flagging high-score trades. The system is particularly effective at identifying institutional positioning changes, earnings plays, and informed trading ahead of catalysts.

Unusual activity is detected in real-time as trades flow through our system with under 100ms latency. Our algorithms process every single options trade across all US exchanges, evaluate them against historical patterns, and calculate Unusual Scores instantly. You can filter, sort, and receive alerts on unusual trades as they happen, giving you an edge in identifying significant market moves before they become obvious.

Yes! With Gamma plan or higher, you can create custom alerts that trigger on specific unusual activity criteria. Filter by minimum Unusual Score, symbols, order type (calls/puts), premium size, and even specific detection algorithms. For example, alert only on sweep orders with scores above 80 in tech stocks, or alert on any unusual put activity in your watchlist. Combine unusual activity criteria with other metrics for highly targeted signals.

Absolutely! All plans include access to historical unusual activity data. You can analyze how unusual trades correlated with subsequent price movements, test different score thresholds, and validate your trading strategies against years of data. This helps you understand which types of unusual activity are most predictive for your trading style and develop confidence in the signals before trading them live.
