how to make an array-based indicator funtion in real time

[john hamon <jhamon@xxxxxxxxxxx>]

list,

i have an indicator that waits until the last bar of the chart and then
loads price data into an array, does a bunch of processing, and then marks
bars and trendlines.  it works great.

here's my problem: when i run the indicator in real time, say on a half hour
chart, the indicator never updates.  somehow i need an event to trigger that
a new last bar is completed (i don't want to run intrabar) to get my
indicator to rerun.

thanks,

jh
