Hi all,

this is my formula file to test alertif function with realtime 
datafeed.when I in insert this custom .afl formula file to current 
symbol which was feed by realtime data.I can not get any sound alert 
automaticaly but to push the button of "apply indicator" in 
this .afl file's formula editor dialog manually.what's wrong with 
it ? I am really confused.How can I get alert through realtime 
datafeed. Thanks a lot for any helps!!!

the symbol is EURUSD with 1min timeframe:


upsig=IIf(C>O+0.0001,1,0);

downsig=IIf(C<O-0.0001,1,0);

AlertIf(upsig,"SOUND C:\\program files\\metatrader 4
\\sounds\\alert.wav", "Audio alert");

AlertIf(downsig,"SOUND C:\\program files\\metatrader 4
\\sounds\\tick.wav", "Audio alert");
