Short HPQ at 35.48, covered at 36.03

Last night I was looking at the 30 stocks in the Dow and HPQ caught my attention for being in a strong downtrend. This morning it opened at 36 and just moved down from there. After it got past some support at 35.50, I placed my first short at 35.48.  My stop is at 36.02, right above today's high and open price.

Support, and my first target, is at 34, given by the early June low.  If it gets past that, there seems to be no bottom.
I am a little worried because MFI is showing some life, however by tomorrow it will have turned down because of today's 3.25% drop.
The principles behind this trade are:

1. A strong trend
2. The overall market is correcting
3. Stay with the trade as long as you can
4. Oscillators pointing down

Covered at 36.03 on July 21, after several days where HPQ qas going nowhere.  I had a sense that the support at 35 was going to be broken, but that didn't happen, and I watched MACD flatten out and never really give a signal, while Stochastics actually turned up and gave a BUY signal!

About staying with the trade, I think that's valid as long as the trade is a winner. When it looks like a minor move happened and now we're sitting pretty for N days in a row at the same level, while the indicators never really give off the proper sell signals I was anticipating, then stops should be tightened accordingly.
