Today is the 5th transaction of 132,000, completed 131074U, consumed 521-514.3=6.7U.

The result is acceptable, trading RLS, there were no ups and downs, at most a small loss of 0.1-0.2U, most of it is normal wear and tear, occasionally can break even or make a small profit.

I feel like I've discovered a trick, not sure if it's accurate, but every time there is significant loss, the price difference basis point after confirming is greater than the price difference basis point at the time of observation; every time breaking even or making a small profit, the price difference basis point after confirming is less than the price difference basis point at the time of observation.

For example, when you see the price difference basis point is 0.5 at the time of confirmation, and when the transaction occurs the price difference basis point becomes 1.5, then this transaction will have a large loss.

Another example, when you see the price difference basis point is 1.5 at the time of confirmation, and when the transaction occurs the price difference basis point becomes 0.8, then this transaction will have a small loss.

Sometimes when the price difference basis point is large, like 7-8, 10-20, suddenly drops to 2 or 3, and when the transaction occurs, the loss of this transaction may also be very small, possibly breaking even or making a small profit.

This is just a feeling, and I still need to practice and try more next.
