As the red arrow above the price bars is showing short selling or profit taking while the volume is increasing (the red arrow above the volume) indication a valuable information on the consistency of the move downward. Alike, the green arrow below the price bars is showing rising interest and buying, while the green arrow above the volume is also signaling soaring interest suggesting an ongoing upward move.
In both cases, the volume is increasing accordingly to price, which means for a down trend that the interest is increasing while prices are falling and for an up trend that the volume is increasing as price is soaring.
This is considered to be a healthy move accompanying the overall trend.
