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
