2nd day off the parabola, which means heading toward an 80% retracement. Target is red line just above 4,3k level.
I suggest you to buy gradually increasing exposure on the way down if you are a long term investor. If you'r technical like I am. well the answer is simple. Watch the daily and wait for a clear reversal. The most relevant levels are pointed in the chart.
I'll check the chart time to time to see if some specific daily pattern is forming. 3 weeks is the minimum range to me for a pattern to be relevant.
