Currently oscillating around 4200, it seems that the longer the oscillation lasts, the greater the probability of a drop below 4000.

The weekend is coming soon, and I hope for two days of oscillation on Saturday and Sunday. Why do I hope for this?

For most people, oscillating markets are the most profitable times; whether the market is rising or falling in a one-sided trend, it often results in losses. This is because in an oscillating market, if you make a mistake and increase your position, you can hold on and recover, whereas in a one-sided up or down trend, making a mistake and holding your position can lead to liquidation.
