Last time from 6000 -> 3000, we experienced the similar down-walk trend, where around 5000-5500 there is a sharp change and move back to the original in a day. Now the history repeat, that is interesting, but in up-trend. I am not going to buy it now, since the 5000 is going to wave up and down quickly for 1-2 days, but I am expecting a sharp up-trend in the next couple days. If this did not happen, we will see what is the next support.
