OI Walls as Support & Resistance
OI walls are strikes with unusually large open interest. They often mark where writers defend or where unwinding accelerates moves.
Reading OI walls near spot
twiQ focuses on strikes near the current Nifty price and ranks the largest OI change on your interval — the same practical window as institutional option desks.
When walls break vs hold
Walls hold when gamma pins and futures do not press through. Walls break when big activity clusters through value and OI unwinds. twiQ combines OI, gamma, and futures pressure for that read.
