The current market can be summarized in one sentence as

Large investors have a low willingness to sell

The current price is not high enough

Large investors lack sufficient motivation to offload

Nor is it low enough

There is no adequate reason to determine that the trend is damaged

Or to drop below the breakeven point

So going forward, we still need to establish a big direction

More consideration should be given to selling out the goods between 75 and 85

Rather than buying more

The best time to build a position has already passed for me
