I am working on Ichimoku system and need to modify it a bit. I need to figure out what the external function is doing? Can anyone help to extract the business logic running behind ExtFml("PowerPivots.SysEval"..)
The forum script is provided such as ST:=(HHV(H,26)+LLV(L,26))/2;
TL:=(HHV(H,9)+LLV(L,9))/2;
A1:=Ref((ST+TL)/2,-25);
A2:=Ref((HHV(H,52)+LLV(L,52))/2,-25);
LE:= If(A1>=A2,Cross(C,A1),Cross(C,A2));
LX:= If(A1>=A2,Cross(A1,C),Cross(A2,C));
SE:= If(A1>=A2,Cross(A2,C),Cross(A1,C));
SX:= If(A1>=A2,Cross(C,A2),Cross(C,A1));
B:=ExtFml("PowerPivots.SysEval",LE,LX,SE,SX,"!@#$#@!");
Buy:=If(TL>ST AND B>0,1,0);
Sell:=If( TL < ST AND B < 0,-1,0);
Buy+Sell<>-1 and Ref(Buy+Sell,-1)=-1
