11/1 Diary: The current level is 2300u. Yesterday I said I would take a break. In fact, I am still working on it, but I am not aiming to make much profit. I am mainly experimenting. In the experiment, there was no change in profit and loss. The missing 15u was because I was so sleepy that I removed the stop-profit and stop-loss orders when I was arbitraging the funding rate on GAS. As a result, I killed the short seller with one pin. , the loss when it falls back. Fortunately, there was no big fall. The lesson is to use a special sub-account to arbitrage, and my current capital amount cannot be arbitraged for more than a few cents. I have picked up sesame seeds and lost the watermelon.
