About

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 |

How to Use

Input: A ticker symbol or market-wide scan request.

Output:

  • Unusual activity list: timestamp, strike, expiry, type (call/put), volume, OI, premium, trade classification
  • Sentiment classification per trade (bullish sweep, bearish block, hedging, earnings positioning)
  • Net premium flow (calls vs puts in dollar terms)
  • Historical accuracy: how often similar signals preceded the expected move
  • Aggregated smart money score

Example Queries:

  • unusual options activity — Market-wide scan of today's most unusual trades
  • smart money AAPL — Institutional flow signals for Apple
  • large trades NVDA — Block and sweep orders for NVIDIA
