Retrieving bar index

[eminitrader]

I have a bar index from a 1 minute time frame and i want to retrieve the equivalent bar index for the 5 minute time. Does anyone know of a function that will allow me to do this?

In Chris Kryza's dsUtilities function library there are two functions that will do that ie dsgetBarIndexAtTime() and dsgetBarIndexAtRawtime(). You can find the function library with its Help file here
