You need to know your stops in advance.
I would pay for a formula that would calculate stops taking into account:
1) an individual's investor's overall risk tolerance
2) a stock's "risky-ness" (I've seen them on some websites)
3) a stock's current volatility
4) the stock's industry trends
5) the size of the trade relative to an investor's entire portfolio
6) where the stock is (oversold/undersold)
7) other relevant company stats.
8) blah blah blah.
the list above is probably garbage....but you get the idea. I've made a lot of errors setting stops (and I have gotten some right) so I could use some help, especially when I get to trading quickly during volatile times.
