🤔💡 Let's talk Open Interest (OI) – something I ignored for too long, costing me dearly early on. OI isn't volume; it's the total number of open contracts, showing new money entering or leaving the market. Rising OI means new positions are opening, confirming strength in the current trend. Falling OI means positions are closing, suggesting trend exhaustion.
