18	There is a close relationship between trading volume and price fluctuations in the cryptocurrency market. In an uptrend, usually, an increase in trading volume accompanies price increases, indicating strong buying pressure. In a downtrend, a significant increase in trading volume may indicate a large - scale sell - off. In different market phases, this relationship varies. In a bull market, high trading volume can sustain the upward price movement. In a bear market, high trading volume during a price drop may signal the acceleration of the downward trend.
