The gap was closed

Some colleagues say that based on the 4H chart, we will have a correction to the 5970 area. Based on the support from the accumulated volume, which is more important, this is the 6070 area. But I ask what is the basis/fundamental of this correction and why now?
I do not see any reason for this. Moreover, at the close of the session yesterday there were strong purchases, probably an entry, as well as even at the close of the market. 1H support was not broken, and at the end we even returned above 5 and 15 min ones. The gap was closed and I do not see signals for such a correction. Please share your opinion?
