This is also the prior breakout point from late December (large yellow bar breaking above two previous bar highs making for classic swing pattern low, but also that is probably when most of the happened.
So a correction back to that level would be entirely natural.
Immediately below is the old swing low which earlier was previous high levels around 177.32, so the is a probable zone (179 - 176) which will at least give market pause on way down, if not actual hold before bounce back up to fill that gap.
If it holds, we go back up to fill the gap from 2 days ago. If it doesn't, look to lower white dotted cluster support.
