I've got questions about shorting........

Do shorters generally have a trailing buy order in place, so that

if the shorted stock makes a up movement it triggers an automatic

buy????? and if so how much up movement does it take to trigger

the buy???? and...do they place a large chunk of shares on top of

the ask to cap the ask and protect themselves if the price tries to go

up???   thanks in advance...I'm still trying to get my head arround the

whole thing and reverse logic---at least reversed to me...lol..

if I can understand it maybe I can fight it.....tnx agn...
