Earned 66u, 426 today. Yesterday's special market rose sharply, causing the grid to lose money for a while, but today's slight correction brought profits. The main reason is that Audi's grid settings are too large and the number of grids is large, which leads to greater pressure to resist orders. Even last night, the highest floating loss was more than 50. But fortunately, it did not reach the upper limit. The disadvantage of wide range is that special market conditions require more margin, and it is also difficult to consider returning to the low point.
