I think a bounce bounce to 4100 or more is coming as part of the larger triangle structure. RSI is quite low and the price action is choppy - like they are winding up for a move out of the channel. 4100 or more would certainly convince bulls that "all is well" and the uptrend WILL continue, but I don't think that would be the case. If anything, 4100 is an ideal short for a larger move down to 3700-3600.
Good luck!
