By adding an initialisation variable to Glens' solution you should be able to pick up the first long
(or short) trade also. This would look like
LongEntry:= {your long entry parameters};
ShortEntry:= {your short entry parameters};
Init:=Cum(LongEntry<>2 and ShortEntry<>2)=1;
LongEntry AND BarsSince(Ref(LongEntry OR Init, -1)) >=
BarsSince(Ref(ShortEntry OR Init, -1))
The following variables lifted from the Trade Binary I posted several weeks ago show how an Init
variable can be used with entry and exit signals to create a useful "flag" showing whether in a long
trade, short trade, or out. This Trade variable has a value of +2 for a long trade, -1 for a short
trade, +1 for both, and 0 for neither. Very useful once you get to grips with it.
Init:=Cum(EnterLong<>2 AND CloseLong<>2 AND
EnterShort<>2 AND CloseShort<>2 )=1;
Trade:=Ref(If(BarsSince(EnterLong OR Init)>=BarsSince(CloseLong OR Init),0,2) +
If(BarsSince(EnterShort OR Init)>=BarsSince(CloseShort OR Init),0,-1),-0);
