[amibroker] Re: Backtest Intraday system - closing open positions?

Listing every single day when the market as closed early is not
possible in a backtest (10 years data and I don't have access to it). 

A bit more background on what I'm trying to do -  I'm running
backtests (day session only) on 1-minute ES futures and I've a number
of trades that happen to hang around until the next session open
(mostly gapping up/down) before closing causing spikes in profits/losses.

Is there a way to find the last quote before a certain time of the day
using AFL and set that as the sell/cover price for any open positions?
