How much volume does a tick mark represent?

The volume represented by a tick mark can vary depending on the context, such as the specific market or trading platform being used. In stock trading, a tick mark typically represents the smallest price movement of a security, while in futures or commodities markets, it can denote a specific dollar amount per contract. To determine the exact volume represented by a tick mark, it's important to refer to the specifications provided by the exchange for that particular asset.
