DD, you may have to think some more on the stop strategy.
Try this indicator code anyway:

---8<----------------------------

{ Date-based entry, trailing stop exit }
{ http://www.metastocktools.com }

{ AdvancedStop.dll must be in
 ...\MetaStock\External Function DLLs\ folder }
{ AdvancedStop.dll by Richard Dale, free from:
http://www.tradernexus.com/advancedstop/advancedstop.html }

{ User inputs }
entryDay:=Input("entry Day",1,31,1);
entryMnth:=Input("entry Month",1,12,1);
entryYear:=Input("entry Year",1800,2200,2005);
x:=Input("entry Price: [1]Open, [2]Close, [3]Weighted Close",1,3,2);
stopLoss:=
 1-Input("Exit x% below entry",0,100,10)/100;
pds:=Input("EMA periods",2,260,50);

{ Entry signal }
entryPeriod:=Year()>entryYear
 OR (Year()=entryYear AND (Month()>entryMnth
 OR Month()=entryMnth
  AND DayOfMonth()>=entryDay));
entry:=entryPeriod AND Alert(entryPeriod=0,2);

{ Entry price }
entryPrice:=If(x=1,O,If(x=2,C,WC()));

{ Trailing stop }
initialStop:=entryPrice*stopLoss;
trailStop:=Mov(C,pds,E);
stop:=ExtFml("AdvancedStop.StopLong",
 entry,initialStop,0,trailStop,0,0,0,0);

{ Exit }
exit:=stop>C;

{ Initialize plot }
Init:=Cum(IsDefined(entry+exit))=1;

{ Remove redundant exits }
binary:=ValueWhen(1,entry-exit<>0,entry-exit);
exit:=
 binary=-1 AND (Alert(binary>-1,2) OR Init);

{ Plot in own window }
entry-exit
