Option Chain सही है, आपका दिन गलत है | The 2 Lakh OI Rule | CA Sumeet Mongia

Kuch log mere last Open Interest video se profit banane lage. Aur kuch logon ne likha — "Sir, aap ka Option Chain wala tareeka mujh par kaam nahi kiya." Dono sahi hain. Kyunki tareeka galat nahi hai — aap use galat DIN istemaal kar rahe ho. That's what this video fixes. I start with a simple satta / matka example — 0 to 9, people place money on each number, and you get to decide which number opens. You will obviously open the number with the least money on it, because that's where you pay out the least. That single idea IS the option chain. Where the crowd's money sits, the market does not want to go. Then I take a live Nifty option chain and show it strike by strike — 23,500, 23,400, 23,300 — who the buyers are on each side, and which side the market has every incentive to hurt. BUT HERE'S THE PART NOBODY TALKS ABOUT — THE TIMING. When you decide which number to open, you assume all the money is already placed. What if betting closes at 5 PM and you decided at 2 PM? In those three hours another ₹10 lakh lands on the number you picked. Suddenly you're paying out ₹99 lakh instead of ₹9 lakh. Your logic was perfect. Your timing ruined it. This is exactly what most traders do — they open the option chain the DAY AFTER expiry and start predicting. At that point the OI hasn't built up at all. You're reading an unfinished picture. SO WHEN SHOULD YOU READ IT? → Wednesday & Thursday — skip it, the data is raw → Friday onwards — the picture starts becoming clear → Monday & Tuesday — the most reliable days to act AND IF YOU DON'T WANT TO WAIT — THE 2 LAKH RULE. Any day of the week, if a Nifty strike crosses 2 lakh OI on the CALL side, treat it as a level the market will struggle to cross — a strong resistance. On the PUT side I look for roughly 2.5 lakh for the same confidence on support. Cross that number and you can place your bet without waiting for expiry week to mature.
