pls help correct my code

New comment
 
First of all, I believe this code is very handy, many ppl will love it. So please help me improve it.

In fact , this code already works great. But I'm just tired of the simple Alert popup, with NO Symbol shown. So I changed/added some lines to try , which is the %%%%%%%%% part.

I don't know why, print, comment... whatever, nothing happens.
And, weirdly, you can see in the "----alert----" part, I changed UPBREAK alert into something else, but it still shows "UP BREAK". ---- I'm sure everytime I rewrite the code, I compile it, delete it from chart and load it again.

Any idea? 

#property indicator_chart_window
#import "usr32.dll"                                                                             // %%%%%%%%%%
   int MessageBoxA(int hWnd,string lpText,string lpCaption,int uType);    //%%%%%%%%%%
#import                                                                                            //%%%%%%%%%%

      return(0);                        // question here: what should I use, 0 or -1 ?
    }

I found what's wrong:

Usually, I create or edit a code by: "Metaeditor---file---new/open..."

But I just find out: after attach to chart, and then some changes in this code, finally more changes do not affect the chart anymore (surely I compiled !)----- but "Metaeditor--navigator--files---my code..." do ! That's weird, they should be the same code!
