when you short, your anticipation is down, if it goes opposite direction, then that was a mistake.
When you should stop-loss? It also depends on your anticipation, RIMM will go up or down from here? If you anticipate it will go down, then you should keep it patiently, and vice versa
Of course, there is a possibility, the new anticipation is wrong again. That is why we make decision based on probability, because we are not sure what will happen tomorrow. |
