When doing short-term trades, you must hold back. It's most suitable when there are rapid fluctuations. I didn't make any trades today, but there were significant fluctuations in pi. I made a few short-term trades and earned 200u, which is fine. First, the Position must be very light; even if you add to the Position twice, the Get Liquidated price is 0. Second, you need to be steady, precise, and ruthless. Seize the opportunity to enter and exit quickly. Don't think about long-term holding during extreme fluctuations.
