#机器人网格 's grandma, the contract and the robot are both about 2000U. In the morning, I opened a large pancake short position by myself, while the robot opened a secondary pancake short position, about 12 hours later. My own contract was stopped out for a profit, earning only 130U, while the robot made 240U. I really don't have much ability to make big money from contracts; it's better to focus on studying the robot.
