Etoke,
The approach I would take would be a double loop. You need to create
a new array with the averages. Make sure that the quote arrays are
padded so that all the bar times are represented. You would loop
through for each of the bars in a day, with another loop that creates
a moving average of all the nth bars. "n" is one days worth of bars.
A formula for doing a MA in a loop was presented a few days ago.
There might be other variations on this theme.
BR,
Dennis
