i have been keeping any eye on MCP for a while. the $19-20 is quite a strong support. today the MCP opened at about $18.4
At this point, i will not short it. I will check it around 3:25pm today. by then, if the MCP is not able to climb back to close to $19, then i will shot it.
when to cut loss? well, whenever it climbs back to $19-$20.
When to take profit? i have not yet know at this point.
