My friend still doesn't quite understand what it means that the high position has obviously decreased in volume and has a high probability of attracting more people?

Let's take a simple example:

When a stall in a hypermarket is about to close (with the highest daily turnover, representing a high position), it is suddenly full of people (appearing at the same time in a short period of time, with strong consistency, representing a decrease in volume), but there is no cheap sale or buy a few get a few free shouts (good news).

Are you ignorant and want to go over to see what's going on? What is the product that attracts this wave of people?

Once you go over (buy goods), you will find that there is actually nothing on the stall. The people who gather are just hired to create an atmosphere and are "drags" (representing dog dealers).

When enough individual customers are attracted, this wave of people will disperse, leaving the ignorant individual customers trapped in the swamp of the stall.

So when you find that the price of the currency is already at a high level but there is still a large amount of funds involved in the unified intervention, you must be alert: high position → high cost, unified → dealer.

The dealer spends a large amount of money to drive up the price of the currency. If it is not to lure retail investors to take over, what is it for?
