Important information:
In order for the market to rise, buying must occur, and the upward movement usually appears in the form of a rising bar (a rising bar is a bar whose close is higher than the close of the previous bar) accompanied by an increasing volume, but this increase in volume must not be excessive, as an excessive increase indicates the presence of offers.
But if you notice that the volume is low while the market is moving up, you should know that you are either lying. The reason for the low volume is that the professionals refuse to participate with their money in this movement because they know that the market is weak. The market may rise without the professionals participating in it, but if the money is not smart. Interested, it won't go away
