AlphaGBM Unusual Options Activity

Detects unusual options activity and classifies smart money signals to help you follow institutional positioning.

What This Skill Does

Concept	Description
Volume/OI Ratio	When today's volume far exceeds open interest, it signals new positioning
Block Trade	A single large transaction (typically 100+ contracts) executed at one price
Sweep Order	Aggressive order that sweeps across multiple exchanges to get filled fast — indicates urgency
Premium Flow	Net dollar amount of call vs put premium — shows directional conviction
Sentiment Classification	Categorizes activity as bullish sweep, bearish block, hedging, or earnings positioning
Historical Accuracy	How often past unusual activity correctly predicted direction
