After my analysis of the whole year yesterday, the market will be very complicated in the next two months. I can only analyze the points, and then choose a good point to place a limit order and wait patiently. The opportunity to make a profit in March is temporarily gone. The risk of holding a position for more than 30 days is relatively large, because there will be repeated fluctuations, and there is no profit if you keep holding it. Especially the funding rate of the contract is burning. This is a summary judgment of the 50 days of 4-5-6. I suggest selling part of it when there is profit, and buying more when it falls. It is a bit difficult to make a pattern and diamond hands in these 50 days.
