non builtinstudies

[wrandall]

The manual to the formula wizard clearly states that you can use the output from one builtin study as the source of input to another builtin study. Can I use the output from a non builtin study as the source of input to a builtin study? If so, what is the syntax for assigning a variable name to a non builtin study and what would be the "dataseriesID" of the non builtin study?

Any help will be greatly appreciated.

At this time you can't use the output from an EFS study as an input to a builtin.

You can use the output of one EFS as input to another EFS though.

Not the answer I wanted but thanks. Next question. Is it possible to return the output from a non-builtin study (i.e. my own custom weighted moving average/envelope) in an offset manner? If so, what is the syntax?

Your help once again would be greatly appreciated.

It is possible...but you have to do the work.

Keep the values as an array and display the ones from the number of bars back you want. It would look something like this (no promises that this is exact, but should point the way):

var myMA = new Array();

main(){

var offset = 5; // 5 bar offset
if (getCurrentBarIndex() - getOldestBarIndex() > 3) { // assume 3 bars in the WMA

   if (getBarState() == BARSTATE_NEWBAR){
       myMA.unshift(0); // Shift array and set first element to 0
       myMA.pop(); // Pop the oldest element of the array
   }

   
    MyMA[0] = (4*Close(0) + 3*Close(-1) + 2*Close(-2) + Close(-3))/10;

    return(MyMA[-offset]);
}
