AMZN Short Holding

I'd like to add to AMZN short, it's not in a bad position, although I consider this more an area to start a new partial position so long as your risk management leaves room to add (I prefer putting the position together in 1/3 or 1/2). I'd like to add to the final position size if we can get above the $270-$272.50 area where there's a gap. I don't think at this time it would be likely, but if the charts developed to give AMZN enough gas in the tank to break just above $278, that would be my ideal area. Keep in mind we are talking las than 4 % here.
