I can't figure out what i'm doing wrong or am I using it it the wrong way .Here's my formula (its a modify version of Patricks "dll latch function"):
{ENTER LONG }
{LE:=H>=Ref(HHV(H,10),-1);
LX:=BarsSince(H>=Ref(HHV(H,10),-1))=10;
{SE:=your Condition here;}
{SX:=your Condition here;}
Z:= ExtFml("forum.Latch",LE,LX,0,0);
EnterLong:=Z = 1 AND Ref(Z,-1) <> 1;
ExitLong:=Z = 0 AND Ref(Z,-1) = 1;
EnterLong-ExitLong; }.

If plotted on a chart in its own window and plot {10} day price channels on price chart I get some signals exiting somtimes {20} days later. I can't figure out why.Why? Thanks in advance Ralph.

Let me know if it is ok for you:

{Enter Long}
LE:=Cross(H,Ref(HHV(H,10),-1));
LX:=BarsSince(LE)=10;
Z:= ExtFml("forum.Latch",LE,LX,0,0);
Z = 1 AND Ref(Z,-1) <> 1

{Exit Long}
LE:=Cross(H,Ref(HHV(H,10),-1));
LX:=BarsSince(LE)=10;
Z:= ExtFml("forum.Latch",LE,LX,0,0);
Z = 0 AND Ref(Z,-1) = 1
