Open interest (OI) is the total number of outstanding futures contracts. It measures market participation and conviction. Key patterns:
  • Rising OI + Rising price → Strong uptrend with new money entering
  • Rising OI + Falling price → Strong downtrend
  • Falling OI + Rising price → Short squeeze, potentially weak move
  • Falling OI + Falling price → Profit-taking, trend may be ending
