Non time-sequential custom series

[probtrader]

In EFS2 I can create custom series by calling efsInternal/efsExternal and using a custom function to produce each value in the serie. However all the series are built sequentially, meaning that the custom function is called for the bar on the chart in a strictly sequential order.
Is it possible to create arbitrary custom series? For example, if I want to put together all the 5 minutes 9:30 bars for the last 10 days in an array, can I pass this specific array to a EFS2 built-in functions?

You can create a custom series of a value or an array using the efsInternal() or efsExternal() functions. However in the case of an array each element of the array would be a series of its own which you would access using the getSeries() function. You cannot use that array as the source of an EFS2 built-in function. You would instead need to process that array in the separate function or efs.

Do you mean something like this?

vMySeries = new Array();
vMySeries[0] = 1;
vMySeries[1] = 2;
vMySeries[2] = 3;

function processArray(pos) {
  return getSeries(vMySeries[pos]);
}

function main() {
  ema(3, efsInternal("processArray"));
} 

How do I pass the right parameter to processArray() from efsInternal()?

For an example on how to use the getSeries() function to retrieve the elements of an array that is being called through efsInternal() or efsExternal() see this thread
