Trading volume plays an important role in identifying trends. Significant trends are accompanied by a high trading volume, while weak trends are accompanied by a low trading volume. When a coin goes down it is advisable to check the volume which accompanied the decline. A long-term trend of healthy growth is accompanied by a high volume of increases and a low volume of declines. It is also important to see that volume is rising over time. If the volume is decreasing during increases, the upward trend is likely to come to an end, and vice versa during a down trend.
