如何在下列信号中加入声音报警信号？
//开多仓条件：
BOPEON1:=C>UPPER AND DIFF>0 AND C>O AND C>MA4 AND HOLDING=0 AND TIME>VMIN AND TIME<220000;
//平多仓条件：
BLIQCON:=HOLDING>0 AND CROSS(MA3,MA2);
//开空仓条件：
SOPCON1:=C<LOWER AND DIFF<0 AND C<O AND C<MA4 AND HOLDING=0 AND TIME>VMIN AND TIME<220000;
//平空仓条件：
SLIQCON:=HOLDING<0 AND CROSS(MA2,MA3);
BUY(BOPEON1,手数,MARKET);
SELL(BLIQCON,HOLDING,MARKET);
BUYSHORT(SOPCON1,手数,MARKET);
SELLSHORT(SLIQCON,HOLDING,MARKET);
参考函数playsound
举例：BUY(BOPEON1,手数,MARKET);
改成
if bopeon1 then begin
BUY(BOPEON1,手数,MARKET);
PLAYSOUND(1,'D:\ONTIFY.MP3');
end
