[amibroker] Is it possible to backtest this in Amibroker?

["tradinghumble" <sharp2be@xxxxxxxxx>]

I have simple system that generate some signals and I believe I can
code it in AB, but then I'd like to choose only the top 3 stocks with
the largest % increase in a certain group of stocks (which had the
signal).... something like

1st Step:
Select stocks from a list (example: SP500) that have have for example
MACD+

2nd Step:
>From the list of stocks that have the signal on step #1, I'd like to
select the top 3 stocks with the biggest % change in the day...

Again, I can code step two but not sure how to go about step # 2? 

Can anyone help by pointing to an example or giving some ideas? Thank
you so much.
