主题：请问版主一个问题

一个图表策略，跟信号用手动操作。能否在信号处添加提示音？

请版主帮忙改一下。

if holding=0 and myfailtrade=1 and time<151500 then begin
 if entrylongcond then
  buy(1,1,limitr,max(open,entryupperband));
end

if holding=0 and myfailtrade=1 and time<151500 then begin
 if entryshortcond then
  buyshort(1,1,limitr,min(open,entrylowerband));
end

if holding>0 then begin
 if exitlongcond then
  sell(1,holding,limitr,min(open,exitlowerband));
end

if holding<0 then begin
 if exitshortcond then
  sellshort(1,holding,limitr,max(open,exitupperband));
end
