Hi, Could you tell me how to write a MetaStock “LOOP” formula? ------------------------------------------------------- Beginning at periods=6 to periods=50 tx:=360*X*periods; cosinepart:=sum(cleandata*cos(tx),50); sinpart:=sum(cleandata*sin(tx),50); pr:=(power(cosinepart,2))+(power(sinpart,2)); Maxpr:=Max(Maxpr,pr); ---------------------------------------------------------------- {How do I then set up the value of dynamic variable “pr”Is the formula below suitable? How do I then put “pr” in a data Array for the Variable Period?} ExtFml( "ForumDll.VarREF", Data Array, Variable Period) ----------------------------------------------------------------- Best Regards. Derek

Derek,
There is no looping function in the MetaStock Formula language. To compute the DFT you will need to use the MetaStock Developers Kit and another programming language to write this as an addin.

==========
Power - variable
==========
{ Power(DataArray,VariablePower) MS function.
With thanks to MG Ferreira.
http://www.metastocktools.com }
{ Data array }
DataArray:=C;
{ Variable Power example }
VariablePower:=DataArray/Mov(DataArray,63,S);
{ Power(DataArray,VariablePower) equivalent }
VarPower:=Exp(Log(DataArray)*VariablePower);
{ Output }
VarPower
