Let's say we have used the Forum.Latch function to arrive a trinary B variable...
I am trying to reverse the position in the market when things are bad.
Does this seem like a correct and/or reasonable approach for this problem?
Any comments would be appreciated.
[code:1:e27b6846a9]
pr := MP();
alphas := .07;
revPct := 1.015;
itrend := ExtFml("ADSI.ITrend", pr, alphas);
trigger := 2 * itrend - Ref(itrend, -2);
LE:=itrend<trigger;
SE:=itrend>trigger;
LX:=0;
SX:=0;
B:= ExtFml("Forum.Latch",LE,LX,SE,SX);
B;
{save the entry price, on the entry day }
LEBar := B = 1 AND Ref(B,-1) <> 1;
SEBar := B = -1 AND Ref(B,-1) <> -1;
EntryBar := LEBar OR SEBar;
EntryPrice := If(EntryBar, CLOSE, ExtFml("ASI.Ref",CLOSE, -BarsSince(EntryBar)));
{ Reverse the position of we are losing badly }
B := If(B = -1 AND CLOSE > EntryPrice*RevPct, 1, If(B=1 AND CLOSE < EntryPrice/RevPct,-1,B));
{We Update B here, I'm not sure if this will effect the workings of the Latch function...}
B;

Thanks,

Brad, anytime the exit/reverse conditions affects the entry (such as in your 1.5% stop), the use of PREV functions are necessary to avoid misalignment between original & new latches. Take a look at this indicator example.
I'm hoping that someone can eventually come up with a PREVless latch DLL for this purpose. ;)
