System tester question

[whardy@xxxxxxx]

If I wanted to set up an indicator that plotted the high and low prices of the first hour of 
EACH day and then plotted that as two straight horizontal lines at the designated prices until 
the next day, is that possible?  It would not need to retain the previous days level, just replot 
after the first hour on intraday charts to the high/low of the first hour.  

Thanks,

Bill Hardy
