Real-time tracking of options transactions to detect unusual activity. Large trades, sweeps, and unusual volume often indicate institutional positioning and smart money bets.
An aggressive order that hits multiple exchanges simultaneously for immediate fill. Sweeps indicate high urgency - the trader wants the position NOW. Strongest flow signal type.
At ask = buyer paid asking price (aggressive buy). At bid = seller hit bid (aggressive sell). For calls, at ask is bullish. For puts, at ask is bearish.
Focus on trades over $100K premium for significance. Over $250K is strong signal. Over $500K is very high conviction. Smaller trades may be retail noise.

Sum of delta exposure from all options flow. Positive delta = net bullish positioning. Negative delta = net bearish. Provides overall directional sentiment.
Gamma Exposure of market makers. Positive GEX = dealers dampen moves. Negative GEX = dealers amplify moves. Affects how market behaves around key levels.
Compare volume to open interest. If volume > OI, likely new positions (opening). If volume < OI, may be closing existing positions. Opening trades more meaningful.
Flow provides direction, technicals provide timing. Best setups: bullish flow at support, bearish flow at resistance, flow confirming breakout direction.
Same strike purchased multiple times over hours/days. Indicates accumulation by same entity. Stronger signal than one-time trade.
Sum gamma across all strikes weighted by OI and spot price. Positive for calls (dealer short), negative for puts. Complex calculation requiring full options chain data.
Strike where net GEX crosses zero. Major support/resistance level. Above flip = positive GEX (mean reversion). Below flip = negative GEX (trending).
