Maybe something like this:
---8<------------------------------------
VVP:=Mo(10)-100; { or Fml("Martin(VVP)") }
{ alert if VVP crosses -2 on prior 3 periods }
pds:=3;
Cross(VVP,-1) AND Alert(Cross(VVP,-2),pds)
---8<------------------------------------
An alternative is to use a variable-period LLV dll.
