The chart above was initially engineered on September 28, 2020. Today I refreshed the chart, keeping all original drawing elements (channels, rectangles, Fibonacci levels) intact (chart below).
The price is in the rectangle marked (iii). The technical indicators that I track are in the state similar to their levels in the second part of August 2020, just before the sharp reversal on September 2nd.
If the chart is correct, I expect a retrace towards 3800-3860 to begin any time in the next few days/weeks.
