[amibroker] How to limit number of trades?

["seneca_kw" <wellswellskw@xxxxxxx>]

I'm using Herman van den Bergen's code for generating random buys 
(thanks Herman):

Y = Random()*100; 
Buy = Cross(Y, 50);

For backtesting comparisons, I need precise numbers of random 
trades:  100, 200, 500 etc.  I searched the archives and tried 
adapting a suggestion Graham made in a somewhat related thread:  

Buy = Cross(Y, 50) AND cum(buy)<=5.

This generated an error message ("buy" undefined). Then my beginner's 
brain tried this:

Y = Random()*100; 
Cond1 = Cross(Y,50);
Cond2 = Cum(Cond1)<5;
Buy = Cond1 AND Cond2;

This reduced the total number of threads from 49,000+ to 396, but did 
not hit the number I specified (4).

At this point, I'm stuck. Help, anyone?

Thanks,
Wayne
