What Trending OI shows
Open interest momentum across the strike ladder, broken into intervals through the session, for index and stock options. Instead of one snapshot of where open interest stands, each row is a slice of time: how much call and put OI was added or removed in that interval, which way the change is pointing, and whether price broke the day's high or low while it happened.
How to read the columns
- Chng. In Call OI / Chng. In Put OI — open interest added or removed on each side during that interval. Positive on the call side with negative on the put side is a bearish lean, and the reverse is bullish.
- Diff. in OI — the two sides netted against each other, so one number tells you which way the interval leaned.
- Direction of chng. — whether the buildup is accelerating or fading compared with the previous interval — a large build that is slowing matters less than a smaller one that is growing.
- Day Strength and Flow — two reads of the same tape — Day sizes the session's net tilt against the option book, with dots for how one-sided the repositioning has been, while Flow scores only the last few intervals, so a stale morning build can't masquerade as live pressure. Unwind and CAS-tail chips beside Sentiment mark stretches where positions are being dismantled rather than built and the classic build-up read doesn't apply.
- Net PCR — the put-call ratio recomputed per interval, so you see it moving rather than as a single closing figure.
- Level Break — a D.H.B. / D.L.B. tag beside the LTP when spot broke the day's high or low that interval, which is how you tell a level that broke on fresh positioning from one that drifted.
Frequently asked questions
It means tracking how open interest changes through the session rather than reading its total. A strike carrying large open interest tells you about accumulated positions, while the change in that number tells you what traders are doing right now.
A daily figure nets everything together, so a morning build that was unwound after lunch looks like nothing happened. Splitting the session into intervals shows the sequence, which is usually where the information is.
It is the change in call open interest netted against the change in put open interest for that interval, so a single number shows which side attracted more fresh positioning.
