Factors leading to the decision:
Major trend is down
Minor uptrend looks like it was a relief rally, and price broke below it in the past 3 days
20-ma was recently lost, pulling moving average traders off the sidelines
The recent high pattern is also at the 20-ma and offers a perfect technical spot for a tight stop
As always, use a tight-stop and if it rips down, let it run and trail stops behind.
