让指标符合条件时,发出警告[MC]

Multicharts/Tradestation 的Alerts/警示功能,蛮常用的..
看盘时当条件符合时,可发出声音来提示.
使用RSI 来举例,当大于70,及小于30要发出声音做警示

程序写法如下:

1. inputs:Price( Close ),Length( 14 ),OverSold( 30 ),OverBought( 70 ),OverSColor( Cyan ),OverBColor( Red ) ;
   
2. 
   
3. variables: var0( 0 ) ;
   
4. 
   
5. var0 = RSI( Price, Length ) ;
   
6. Plot1( var0, "RSI" ) ;Plot2( OverBought, "OverBot" ) ;Plot3( OverSold, "OverSld" ) ;
   
7. 
   
8. if var0 > OverBought
   
9. then
   
10. SetPlotColor( 1, OverBColor ) else
    
11. if  var0 < OverSold
    
12. then
    
13. SetPlotColor( 1, OverSColor ) ;//这里提一下,这是让线变色的写法.
    
14. //==到这里都是RSI 指标
    
15. condition1 = var0 crosses over OverSold ;
    
16. if condition1
    
17. then
    
18. PlaySound("C:\Windows\Media\WindowsBalloon.wav")  //填上音效的档案路径 else
    
19. begincondition1 = var0 crosses under OverBought;
    
20. if condition1
    
21. then
    
22. PlaySound("C:\Windows\Media\ring.wav");//填上音效的档案路径
    
23. end;
