Many people are probably short now, so go long?
If we go LONG now, it can take one, two weeks, to 4750/4950 (between fibonacci ret. 0.382 and 0.5) depends on where you look, then a fast way down, probably before end of this month, maybe begining of next, the rock botton should be between 21-2300 - 28-3000 (MA200).
If we go SHORT now, it will get more bumpy down with ups and downs, can maybe take one month longer to reach rock bottom.
Then the rock bottom could go even lower maybe around 11-1300 - 19-2100 depends on where you look.
