Looking at market from Theory there is two bear scenarios:
1. (red arrows and small letters a,b,c) move from 350 to 450 was wave b which means we are to experience wave c now. market is likely to drop towards 350
2. (blue arrows and capital letters A,B,C) wave B from 150 to 450 finished. We have just started wave C which is going to at least re-test previous low of 150.
Stop loss level for short positions around $450-455
Myself I do not mind price increases either. But current longs:shorts ratio is alarming in my opinion. Also breakout from such a long triangle should be decisive and volume normally rises 100% or more. If you check weekly volume on most exchanges it increased just by 30-40% which means it does not confirm price action.
