Open Interest (OI) indicates the total number of contracts currently open in the market.
-> It reflects whether new cash is flowing in or out.

🧠 When combined with price volatility, we can determine:
✔ Who is controlling the market (Long or Short) -> Avoid traps (bull trap / bear trap)
✔ Is the trend still strong or has it weakened?
✔ Is the market attractive, or is it just a 'false' increase or decrease due to closing positions?
✔ Catch the trend early and make more confident trades
