FAQs
What is a Put Wall in options trading?
A Put Wall is commonly described as a strike with a large concentration of put open interest, often below the current market price. Traders may watch it as a potential support area, but it is not guaranteed support.
What is a Call Wall in options trading?
A Call Wall is commonly described as a strike with significant call open interest, often above the current market price. Traders may monitor it as potential resistance, but price can move through the level.
Is a Put Wall always support?
No. A Put Wall can act as a useful reference for potential support, but open interest alone does not guarantee a bounce. Price, volume, expiration, options flow, volatility, and broader market conditions can all affect the outcome.
Is a Call Wall always resistance?
No. A Call Wall is not a guaranteed ceiling. If buying pressure is strong or market conditions change, price can move above the strike. Treat it as an area to monitor rather than a fixed barrier.
How do Put Walls and Call Walls change?
They can change as traders open, close, roll, exercise, or allow contracts to expire. New options activity can also create larger concentrations at different strikes. That is why wall analysis should be updated rather than treated as a permanent map of the market.
