Reading Options Flow

Understanding what big options trades tell you about market direction.

What is Options Flow?

Options flow refers to the buying and selling activity in the options market. Large traders often use options to make big directional bets.

Why Options Flow Matters

  • Leverage - Options amplify returns, so big money uses them
  • Leading indicator - Options activity often precedes stock moves
  • Sentiment - Shows what smart money expects

Key Concepts

Calls vs Puts

  • Call buying = Bullish bet
  • Put buying = Bearish bet

Sweeps vs Blocks

  • Sweep = Aggressive, fills across exchanges (urgency)
  • Block = Single large order (negotiated)

Opening vs Closing

  • Opening = New position (conviction)
  • Closing = Exiting position
