1, the highest bid price is the same as the lowest bid price, and this price is the transaction price;

2. When the declared buying price is higher than the lowest declared selling price displayed immediately, the lowest declared selling price displayed immediately is the transaction price;

3. When the selling declared price is lower than the highest buying declared price displayed immediately, the highest buying declared price displayed immediately is the transaction price.

According to the above principle, the higher the price you pay, the more you can buy it. A bid price, a seller, a previous transaction price, the largest of the three prices becomes the latest transaction price, so your declared price should be close to the previous transaction price, and the higher it is, the more you can buy it.
