Hi,
Here is my problem.
I would like to put values returned by several indicators in an array.
(then to use this array with an external function).
How to do It?
For example, I have three EMA
EmaD:=Mov(C,pdsD,E);
EmaW:=Mov(C,pdsW,E);
EmaM:=Mov(C,pdsM,E);
I would like to put this three EMA in an array.
How to do it?

Hi,
Here is a possible solution but I'm not sure if that's what your are looking for. You could either average the 3 EMAs and combine them to produce a single data array. The solution is:
EmaD:=Mov(C,pdsD,E);
EmaW:=Mov(C,pdsW,E);
EmaM:=Mov(C,pdsM,E);
SMEMA:= (EmaD+EmaW+EmaM)/3 (or you could not average them just produce the sum of those)
That will give you one array and you could input that array in an indicator - e.i.ROC(SMEMA,5,%)
Hope it helps,
VT

It doesn't help me ;(
I need to get the exact values of the indicators in an array.
Moreover, it was an example, it could be EMA, Price and a Boolean to put in array.
Thks to have tried btw ;-)

For example, I have three EMA
EmaD:=Mov(C,pdsD,E);
EmaW:=Mov(C,pdsW,E);
EmaM:=Mov(C,pdsM,E);
you could use the Formula Variable Call Function
fmlvar("formula_name","variable_name")
or Formula Call Function
fml("formula_name")
to define your data arrays

I think you have to use 3 params/arrays
e.g.
EmaD:=Mov(C,pdsD,E);
EmaW:=Mov(C,pdsW,E);
EmaM:=Mov(C,pdsM,E);
ExtFml( "mydll.myfunction", EmaD, EmaW, EmaM)
and in msx in your function "myfunction" in your dll "mydll" - you will need 3 MSXDataArray as Inputs

There is no way to add the 3 params in one array...
to call ExtFml with only one array which would contains 3 values??
Such as:
EmaD:=Mov(C,pdsD,E);
EmaW:=Mov(C,pdsW,E);
EmaM:=Mov(C,pdsM,E);
EmaArray:= RHAAAAAAWhyItDoesNotExist(EmaD, EmaW, EmaM);
ExtFml( "mydll.myfunction", EmaArray);

correct ;)
the MSXDataArray is only a "vector" and you can only transfer 1 indicator (Security) per param to your dll

But it would be possible to write a msx-function wich adds indicators to a matrix as new column...
e.g.
EmaD:=Mov(C,pdsD,E);
EmaW:=Mov(C,pdsW,E);
EmaM:=Mov(C,pdsM,E);
ExtFml( "mydll.addCol2Matrix", EmaD);
ExtFml( "mydll.addCol2Matrix", EmaW);
ExtFml( "mydll.addCol2Matrix", EmaM);
the matrix must be a global var in your "mydll" - like it is in the gv.dll (globalVar)
Afterwards you would be possible to store the wwhole matrix with an other function:
ExtFml( "mydll.saveMatrix", "d:\mytest.csv");
