Backtesting

#1
I am doing backtesting.

What I have is a list of tickers with the dates on which each one is to be traded. eg.

IBM 4-JAN-2010.
TXN 5-JAN-2010. and so on.

I would like the backtester to pickup up the ticker and trade on the specified dates.

I cannot figure it out how to write an AFL for this?

Any help would be appreciated.
