Heap volume is an orderly and moderate increase in trading volume, reflecting a healthy rising pattern.

When the main force wants to pull up, it often makes the turnover beautiful. In the past few days or weeks, the volume of transactions has been gradually enlarged, and the price of futures commodities has been slowly pushed up. On the recent K-line chart, the turnover has formed a mound shape. The more beautiful the pile, the more likely it is to produce a big market. On the contrary, the high pile indicates that the main force has stopped playing and is shipping on a large scale.
