Ah-ha...that's another trick for putting in the trailing stop...when? Again, I'm just a "rook" so others here are faaaar more adept to this stuff than I am, but good point.
As for SIRI - I also won't put one on until a few days before the actual Q3. It's the 9th, Monday, so I'll do it the week of the 2nd. As you mentioned, waiting let's the dips wash out some before you feel it's really in for a good consistant climb. That's when I'll set my trailing stop.
Percentage or dollar on SIRI? I've only played percentages, so I'll go with that on SIRI. I had good luck with both 2% and 3% but I'll wait and see where I am profit-wise, how much it's daily fluctuation has been, and how much am I willing to loose based on the percentages before the stop triggers. (Putting 2% on C was spooky given it's volume/bouncing abilities but it worked great for me yesterday.)
To summerize, it's like BigBen said, it's not just about knowing when to get in -but when to get out and TO HOLD WHAT YOU'VE GOT! I look at my past 6 months performance chart and I see some fairly large dips. I wasn't utilizing trailing stops back then. At worse now I see a slight drop after the high (when the trail triggers), but it never drops like it used to.
If I had a trailing stop in the morning back on the 7th when SIRI's bottom fell out I would have never had to make up the $1200. loss. Lessons learned.
Siriustunes; as for LVLT, I've got them on my "Watchlist". Yeah, so much for listening to your brother! The volume has been deflated but keep an eye on them. Are they still waiting for the federal stimulus funds they requested to get approved? I think they are. If that's the case watch for another rise up.
Megahertz out.
