1 The increase in trading volume (indicating active transactions), the increase in positions (indicating that funds are actively entering the market) and the upward push of prices (indicating that bulls are actively opening positions and pushing up prices) can be done more.

2. The volume shrinks and the position is reduced (indicating that the funds are out). If the price falls at this time (indicating that many parties actively close their positions and leave), they can be short.

3. As the turnover increases, the positions also increase. If the price falls (indicating that bears are active), you can short.

4 the volume of transactions decreased, the positions also decreased, and the prices rose (indicating that the short positions were actively closed).

There are two conditions that need to be observed and combined with graphic analysis:

A If the graph of volume increase, position decrease and price increase is at the bottom (indicating that short positions are mainly closed, it is advisable to wait and see), if the graph is at the top (still indicating that short positions are closed, on the eve of the surge).

B trading volume increased, positions decreased and prices fell. At this time, many parties took the initiative to close their positions. If funds enter the market, positions increase and prices can rebound.

The first four situations are the most reliable. The latter two are not sure.
