Of course, one second after the transaction, it is either a loss or a profit. To put it simply, if you buy it for 3,000 yuan, the price will drop to 2,990 immediately, and then you will lose 10 yuan one ton.

As for ultra-short-term, not to mention tens of seconds, even 5-second transactions are common. There is no requirement for the scale of funds, but it is fast.
