europe, us, and early asia markets all tumble;
small gap on yesterday's hourly chart has been filled. skynet seems reference-worthy for a couple of days now, which casts the immediate resistance and support for today respectively at 24410 and 24120 levels.
wave amplitudes of the range-trading region since Jan 13 have been increasing steadily (reverse triangle), also on hourly chart.
--> any breakthru above 24420-24462 or below 24400 with volume might initiate further wave expansion, technical trader should look closer to synchronized signals on charts of various time frames.
