Not trying to be pessimistic but there is a lack of volume on this "crash", so it does not look like a bottom.
We need to go back to the 2017 uptrend in log to find support levels. We just broke uptrend (C) and the 62% retracement.
If we look at the fib levels of 2017 advance we get a 78% retracement at 4100-4500 EUROS.
So we are not done, we need to see big volume when the US wakes up.
