In a previous publication we discussed the anchor points for the base forming of the current correction phase.
The current reference point is 1677
the point above the reference point is 1725
below the reference point we have 1657 as the anchor point.
The mean reversion of the completed growth phase is at 1621 level,
All three Mean Reversions were between 42 to 45% of the growth phase
Currently, from 2075 to 1677, the mean reversion completed 43.49% of the 915 points growth from 1160
So 1677 stands as a valid base currently until it's broken, then we can expect 1657 or the exact 50% at 1621 to form the base.
Stay safe, good luck.
