For example, Mr. Wang bought the opening contract of Shanghai Natural Rubber 10 lot 6 10 lot, and the transaction price was 25,000 yuan/ton. After the transaction, the price changed. Considering Mr. Wang's own trading style and risk tolerance, he thinks that when the price drops to 24,200 yuan/ton, the market will go down rapidly. In order to avoid the loss of placing an order at that time, he issued it through the trading system. Sell 10 contract of 6 10 Shanghai natural rubber, with the price of 24,200 yuan/ton, and the nature of the instruction is [stop]. When this order is issued, once the market hits 24,200 or the price is lower than 24,200, the order will automatically reach the exchange system for transaction at the first time. Otherwise, the market will not touch or break through the price of 24200.

On the contrary, the touch price instruction is to set a price higher than the current price. That is, when the price is 25,000 yuan/ton, set a value higher than this price, and execute the instruction when the price reaches.
