1, 10% open position change, which is worth noting; 25% change represents the main trading information. Whether the open position is rising, falling or flat depends on whether the price is rising, falling or developing horizontally at that time.

2. The increase in open positions in price increases can confirm the upward trend. Bulls can overweight, which means that bears keep coming in. When they admit the failure and make up for it, the purchase will further push up the price.

3. The increase in closing positions during the price decline indicates that the low-end undertakers are quite active. Bears can continue to overweight, because when bulls come out, their selling pressure will further force prices down.

4. In the horizontal trend of price, the number of open positions increases, which is a sign of short positions. In this price trend, most short positions come from commercial hedgers, not speculators. If there is no obvious price trend, the opening of positions will increase greatly, indicating that smart risk averse people are shorting the market.

5. The decrease of open positions in the horizontal price trend indicates that business risk aversion is covering, which is a buying signal. When business users start to make up, they are bullish.

6. The decrease in open positions during the price increase shows that both winners and losers feel "cold feet". Long profit-taking and short compensation cover. The market will reflect the future in advance, and if most people accept a certain trend, it means that the trend is about to reverse. If the opening position decreases during the price increase, end the long position and prepare to short.

7. When the price falls, the open position decreases, which means that the short position gains and the long position confirms the loss. In this case, you should make up your position and prepare to buy.

8. Opening positions leveled off in the price increase, which is a warning of the aging trend of the upward trend, and the upward trend has lacked stamina. In this case, bulls should adjust the stop price to avoid new buying. On the other hand, if the open position flattens in the price decline, it means that the downward trend is mature, and it is best to adjust the stop loss price of the short position. If the price is equal to the opening position, it is meaningless.

The higher the opening position, the more active the market, and the less serious the price difference between import and export. Short-term traders should focus on the market with the highest open position, and in the futures market, they should choose the monthly contract with the largest open position.
