Here's how to do PREV in a loop (I can't check the code because I don't have
the deltav values, but this should give you an idea of what to do):
// MetaStock Code
// TLevel:= if(C=PREV,PREV,if(prev>Ref(C,-1),Min(C,deltav),Max(prev,C))));
TLevel = 0; // Indicator to calculate, TLevel[i-1] = MetaStock PREV
PREV = 0;
for (i=1; i<BarCount; i++) {
PREV[i] = TLevel[i-1];
if(C[i] == PREV[i])
TLevel[i] = PREV[i];
else {
if(PREV[i] > C[i-1]) {
if(C[i] < deltav[i])
TLevel[i] = C[i];
else
TLevel[i] = deltav[i];
}
else {
if(PREV[i] > C[i])
TLevel[i] = PREV[i];
else
TLevel[i] = C[i];
}
}
}

David

My apologies ... you do need a loop. It is a circular reference
