Re: [EquisMetaStock Group] LLV: "...must contain only constant data"

Try this. No guarantees but the use of LastValue() and PREV in this manner does work sometimes.
Unfortunately sometimes it does not.

VVP:= FML("Martin(VVP)"); {ref to my formula}
PerSinceLower:=BarsSince(VVP<-1); {Periods since result has been  under -1}
LowestValue:=LLV(VVP,LastValue(PerSinceLower+PREV-PREV));
{Tries to determine the lowest value since result has been under -1}

If this doesnt work you could try making the LLV variable the result plot for the indicator and then
use an Fml() call to apply the value to the rest of your code.

VVP:= FML("Martin(VVP)"); {ref to my formula}
PerSinceLower:=BarsSince(VVP<-1); {Periods since result has been  under -1}
LLV(VVP,LastValue(PerSinceLower+PREV-PREV));
