Trading Volume refers to the number of shares or contracts of a security that have been traded during a specific period of time, such as a day, week, or month. It is often used as an indicator of the level of activity and liquidity in a stock or market.Generally, a high trading volume suggests that a large number of investors are buying and selling the security, which can indicate strong investor interest or a high level of volatility. A low trading volume, on the other hand, may indicate less investor interest or a lack of liquidity in the market. Trading volume can also be used to confirm a trend in the price of a security, as a rise in price accompanied by a high trading volume is considered to be a stronger indication of a bullish trend than a rise in price with low trading volume.
