[amibroker] Data Issue with 1 minute IQFEED data

["trfy1120" <trfy1120@xxxxxxxxx>]

I have a database of some US stocks in Amibroker created from IQFEED.  The data display appropriately in charts.  In Quote Editor, however, it is clear that there is some duplicate data.  For example, I can scroll back through 7/14 data to 7/13 data but if I go farther I get more 7/14 data.  I think I set up the database appropriately.

I believe this duplication is causing inaccurate values when I use timeframegetprice in a script.  I have two questions.  How can I clean up the data?  And, how can I avoid this issue in the future?

Thank you,

TRFY1120
