[amibroker] Re: can not show buy or sell signal arrow

["cstdc5588" <cstdc5588@xxxxxxxxx>]

Hi All,

I have a new computer and installed AmiBroker Pro 4.8 version 
yesterday. I run a simple formula which worked in my old computer. But 
it can not show buy or sell signal arrow in my new computer.  Below is 
the formula: 

Cond = Cross( MA (Close, 10), MA(Close, 20) );
Cond1 = Cross( MA (Close, 20), MA(Close, 10) );
Buy = Cond;
Sell = Cond1;
AlertIf( Buy, "SOUND C:\\Windows\\Media\\Ding.wav", "Audio alert", 1 );
AlertIf( Sell, "SOUND C:\\Windows\\Media\\Ding.wav", "Audio alert", 2 );

Could you please teach me how to solve this problem.

Thanks a lot.

Robert
