When trading, you must learn to wait; opportunities are created through patience. If you don't learn the order placement methods and trading logic of experts, you will always incur losses. Even if you have temporary profits, you will ultimately drop to zero. To get to the point, the following positions can be waited on and set up slowly: go long at 2451-2420-2403 (stop loss, if the hourly close falls below 2400, take profit at 2560, 2580, 2640). Go short at 2625-2655, average price 2640 stop loss (if the hourly close holds above 2675, take profit at 2500, 2475). Build a position in batches of 1+1+2, and strictly maintain risk control.
