A very simple code needed

[mar]

Hi forum!

I started learning MQL4 now but it's not easy at the beginning. I am not new to programming (I also program VB, VBA) but the syntax and the declaration of variables seem to be pretty complex. Therefore I want to know if somebody could give me a very short code just for my orientation. The indicator should only play a sound and draw an arrow if the last bar has a higher high then the bar before. That's all. I only want to know how a good programmed code looks like. Then I can use this small code to keep on learning and testing. But at the moment I don't even know how to create a structure in the Metaeditor. I only wrote down // My first MQL4 try... And that's not enough... ;-)

Thank you very much!

Take

#property indicator_chart_window
int inddir[1];
string dir[1];
int start() {
   if(High[1]<High[0]&&inddir[0]!=0){
    inddir[0]=0;dir[0]="UP";_object();_alert();}
   if(Low[1]>Low[0]&&inddir[0]!=1){
    inddir[0]=1;dir[0]="DOWN";_object();_alert();}
  return(0);}
//---- void function ----
int _alert(){
  Alert(Symbol()," Direction Changed ",dir[0]);
  return(0);}
//---- draw ----
bool _object(){
 if(ObjectFind("Direction")>-1)ObjectDelete("Direction");
 double price=Bid+(High[0]-Low[0])*2*(0.5-inddir[0]);
 ObjectCreate("Direction",OBJ_ARROW,0,Time[0],price);
 ObjectSet("Direction",OBJPROP_ARROWCODE,6);
 ObjectSet("Direction",OBJPROP_COLOR,Gray);
 ObjectSet("Direction",OBJPROP_WIDTH,1);
 return(0);}

Or variant with text
