What are OI Walls?

An OI Wall is a strike price where open interest is so heavily concentrated that it acts like a gravitational force on the underlying price. The Call Wall — the strike with the highest call OI — functions as resistance: dealers short those calls must sell the underlying as price rises toward it, creating a natural ceiling. The Put Wall works in reverse as support.

For SAIL (SAIL), the chart above aggregates OI across all expiries. The highlighted bars are the dominant walls — levels where institutional hedging flows are concentrated right now.
