[amibroker] How to use EOD data in Mixed EOD/intraday setting

[jnz88]

Hi,
With a database having both EOD and intraday data, I am writing a AFL
for intraday scan. In the intraday script, how do I use EOD day?
For example, I want to know 3 month daily volume moving average which
is only from EOD data ( since intraday data only cover around 5 days 
and TimeFrameSet is less accurate than EOD data )
How to do it?

thanks,
