Hello,
Provided that all your NASDAQ stocks are assigned
to "NASDAQ" market (see http://www.amibroker.com/guide/h_categories.html )
it is quite easy:
in AA window, select "Apply to: Use Filter"
and click "Define..." button next to it and select
Market: NASDAQ
from the combo.
Best regards,

Subject: [amibroker] Possible to Backtest Only a Specific Exchange, e.g. NASDAQ?
> 
> 
> Hello,

> I was wondering if someone has ever tried backtesting only a specific 
> exchange.  I am interested in trying a backtest that would allow only 
> NASADAQ stocks, and reject others.  My database in AB is the entire 
> group of all 3 exchanges (NASDAQ, NYSE, AMEX), and normally when 
> I 'fire up' my backtests I click the 'All Stocks' radial button.  I 
> guess I only need some kind of code similar to this pseudo-code:

>  If exchange (ticker) = 'NASDAQ'
>      continue
>  else
>      reject
> 
> My problem is that I don't know how to refer to 'exchange'
