Yuki, Have you used Categories->Groups to setup custom time frames for your different tickers, especially futures that trade outside regular hours.
When you do this and check "day session only", all of those extra bars are effectively invisible. They do not show on charts. They do not compute in any indicators. They do not "count" in BarIndex(). It's as if they don't exist. -- Terry -----Original Message----- From: amibroker@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Yuki Taga Is there, or can you create, an automated routine that would purge any data in a database that is time-stamped outside of user-selected boundaries? For example, I would like to delete *any* data from my RT database that is time-stamped outside of the periods 9:00 am to 11:00 am, and 12:30 pm to 3:10 pm. If it's not in those ranges, it's invalid, period. But as I explained, eSignal puts at least one phoney bar in there every single day.
