When the demand exceeds the supply, the crowd is surging, and everyone wants to buy it, so the transaction volume will naturally increase;
On the contrary, the supply exceeds the demand, the market is deserted, the buying gas is scarce, and the trading volume will inevitably shrink.
Digitizing the crowd is the transaction volume.
The principle of judging the market trend by the volume of spot asphalt;
(1) The gauge line falls, while the price of asphalt rises, which is a signal to sell asphalt.
(2) The quantity line rises while the price of asphalt falls, which is a signal to buy asphalt.
(3) When the volume line turns from positive cumulative number to negative number, it is a downward trend, and asphalt should be sold and held; On the contrary, the quantity line turns from negative cumulative number to positive number, and asphalt should be bought.
(4) When the volume line rises slowly, it is a buy signal. However, if the volume line rises rapidly, it implies that energy cannot maintain a large volume for a long time. This is not a buying signal, but a selling opportunity.
Of the above four principles, (1) and (2) are more applicable.
For the application of calorimeter, we should pay attention to how it cooperates with asphalt price, especially the breakthrough of resistance area of asphalt price trend. Whether energy tide can cooperate is the main key.
Generally speaking, observing the stock market after a period of consolidation needs to know when to leave the market and the future trend when it breaks through.
The change direction of volume line is an important reference index, which is also the biggest application of volume line. There are also some shortcomings in judging the trend of crude oil price with the volume line:
① Volume index is an important method to judge short-term operation technology, which only involves technical factors of price and quantity, and has nothing to do with fundamental factors, so its application scope is limited to short-term operation and is not suitable for long-term investment.
(2) If the total stock market turnover or single crude oil turnover is huge on a certain day, and the crude oil price fluctuates greatly on that day, the final weighted crude oil price index or closing price is the same as the previous day, and the cumulative volume of the trading volume line is the same as the previous day. As far as this line is concerned, it means that there is no signal on this day, but further discussion shows that even if the closing price of crude oil does not rise or fall, the real structure and popularity trend of the stock market are changing, but the trading volume line is slow to respond, which is a great pity.
