Why trading volume matters?

Trading volume is simply the total number of shares traded including both buy and sell orders. If a stock has appreciated on high volume, it is more likely to be a sustained move compared to an appreciation with low volume. Typically, high volume trading sessions are considered significant occurrences and closely watched by traders.
