Resistance is the opposite of support—a price level where a rising stock tends to stall or reverse because selling pressure overwhelms buying demand. It acts as a ceiling that the price struggles to break through. The more times a stock has failed to move past a particular level, the stronger that resistance is considered to be. When a stock finally breaks above a resistance level with strong volume, that level often flips to become the new support. Resistance levels are a core concept in technical analysis and are used by traders across Indian equity, F&O, and commodity markets to set profit targets and plan trade exits.
