Open Interest Maximum Pain Shift
A max pain shift is when the max-pain strike moves during the expiry cycle as open interest builds and unwinds across strikes.
Because max pain is computed from current open interest, it is not fixed — as writers add or close positions at different strikes through the week, the max-pain level can drift up or down. Watching this shift shows how option-seller positioning is evolving and where the market may gravitate by expiry.
Indian Nifty and Bank Nifty traders track the daily max-pain level alongside OI changes to update their expected expiry zone. A steady drift of max pain toward the current price, with supporting OI build-up, reinforces the pin tendency near weekly expiry.
