There is no hard and fast rule. Using BRG as an example which has gone a bit parabolic, $3.60 / $3.80 is a zone of support that should hold if everything's going good, but that also mean giving back a fair chunk of your profit (currently ~$1 per share). If you are not willing to risk so much open profit then you will need to have a higher stop.
It is not fool prove and sometimes you end up selling at a temporary low point only to see the share flies up afterwards.
Given that BRG is driven by the profit results I doubt it will fall flat in an instant. When it reaches a temporary "consensus" price zone you will see congestion pattern.
To be honest, if it hit $3.60 again, so long as fundamentals hadn't changed, I'd actually buy more!
I guess this is why I find stop-losses (and exiting in general) puzzling...
