Quote from traderNik:
Christ, just looked at that chart you posted. You look in the dictionary under 'Don't short this stock!!" and you'll find a picture of this chart. Unbelievable that anyone would think this is a high percentage short, for about 3 or 4 separate, unrelated reasons.
Perfect symmetrical triangle in an uptrend. The mistake the OP made was shorting it after it broke out of the triangle, through the previous resistance level and continued to rise, making a new high.
Once price makes an all-time high, there is no resistance, there are no losers among the AAPL shareholders now.
The only short signal would be a lower high at this point.
