[amibroker] newbie question... searching the database

[bigitop]

I'm writting a basic system to generate buy/sell signals. The
backtester will be set to a 'Date Range' of two weeks and 'All
Symbols' from the database, but I would like the script to search and
process the data by date instead of by ticker. For example: within the
given date range, calculate the average low price of all tickers in
the database for day 1, day 2, day 3 and so on... Is that possible
with AFL?
