MIDCPNIFTY Options — Where Positioning Sits Today

Where MIDCPNIFTY open interest sits

The heaviest call open interest is at the 14,000 strike, holding 9,94,560 contracts — 22.9% of all MIDCPNIFTY call open interest on the board, 5.22% above the spot of 13,305. Call open interest concentrated above price is commonly read as resistance, on the reasoning that writers there are defending the level. It is a crowding observation, not a rule — the level holds until that open interest unwinds.

On the put side the weight is at 13,000 with 8,30,760 contracts, 17.6% of MIDCPNIFTY put open interest, 2.30% below spot. Put open interest concentrated below price is usually treated as support for the same reason, and breaks the same way.

What MIDCPNIFTY's PCR is saying

MIDCPNIFTY is carrying 47,07,000 contracts of put open interest against 43,39,080 of call, a put-call ratio of 1.08 — mildly put-heavy positioning. PCR has no universally good value; it is read against its own recent range, and the direction it is moving carries more than the level.

It opened the session at 1.32 and has fallen to 1.08 — a move of −0.23. Calls have been added faster than puts since the open, the reverse footprint — fresh call writing above spot, or puts being closed.

MIDCPNIFTY against its max pain

Max pain for MIDCPNIFTY computes to 13,300, with spot at 13,305 — effectively on the level. That strike is where the total payout to option buyers at expiry is smallest. It is a level read from the current Open Interest distribution, not a prediction, and the distribution keeps changing.

The pain curve around it is flat — the total payout at the neighbouring strikes is only 0.7% higher than at 13,300. A basin that shallow means several strikes have almost the same total payout, so the level is a loose reading and small shifts in Open Interest can move it.

There are 26 sessions to expiry. This far out the figure moves as positions roll. It is a level read from the book, not a target.

What changed in MIDCPNIFTY today

The largest fresh call position went on at 14,000, +3,75,360 contracts (+60.6%). Its premium rose over the same window, pointing to buyers lifting the strike rather than writers selling it.

On the put side the heaviest addition is at 12,600, +1,43,400 contracts (+1298.9%). Premium fell alongside it — put writing, which is usually read as support being built at that strike.

The biggest unwind is −20,280 put contracts at 13,000. Positions closing matters as much as positions opening — a level defended by open interest stops being defended when that open interest leaves, and a break through a strike that is unwinding is a different event from a break against one that is intact.

Change is measured against this session's opening snapshot rather than the previous close, so the overnight gap and the positions rolled at the open do not swamp the reading.
