Demand

It is the consumer's desire to purchase a particular good or service. Demand is influenced by various factors, including market sentiment, economic conditions, and investor preferences.

For example, if investors are optimistic about the prospects of an asset, they may be more willing to buy it, which can drive up demand and increase its price.

Demand is often measured using trading volume, which represents the total number of units of an asset that are bought and sold during a particular time period. High trading volume typically indicates strong demand for an asset, while low trading volume suggests weak demand.
