Waking up, this market is really exciting, it feels like just a couple of days ago it was about to hit a historical high, and today it's the 4000 defense battle.

This market keeps rising when it says it will rise, and keeps falling when it says it will fall.

At this position, it's likely to fluctuate during the day, and by the afternoon or evening, it might break below 4000. If it drops to this level, it would be hard to justify not piercing down a bit.

The market reverses very quickly; looking at the current trend, the main theme in the future will likely be rebounds followed by declines.
