The magic rules? There are only three, but you must follow them carefully:
Buy near an upward trendline. This implies, by the way, only buying stocks that have actually had an upward trendline. So, if you can't find a trendline for the dog you're looking at, your decision should be simple. Don't buy.
1b: An alternative to No. 1 is to buy near a previous breakout area. Hopefully, this breakout area will now prove to be support. Like the trendline example, though, if you can't figure out where the previous breakout area was, don't buy.
1c: A final alternative is to buy at a bottom. This is my least favorite method, as it implies picking up some real bowsers, in the hopes that "it just can't get any worse than this!"
Only buy if volume has steadily declined on the pullback. Why? Because that's a good indication the selling is drying up. At least that's the hope.
Make sure you use a judiciously placed stop right in the "whoops -- I guess I was wrong" area. That stop can be either on the books or mental, but you must adhere to it. Unless, of course, you want to turn a small loss into a big one.

Remember the pitch Joe Carter belted out of the park to win the World Series in '94? Remember the ball Havlicek stole to beat the 76ers? 
(Man, you are old.) When you get crushed in an options trade, you know what it feels like to have been on the wrong side in all three of those nightmares.
