Draw arrow or line

New comment
 

Hello!

How can I make option of drawing arrow or line? I tried like this but it does draw arrows but not lines. Any idea?

extern int Style=1;
int init(){
   if (Style==2){
      SetIndexStyle(2, DRAW_ARROW);// UP
      SetIndexArrow(2, 233);
      SetIndexBuffer(2, bullish);
      SetIndexStyle(3, DRAW_ARROW);// DOWN
      SetIndexArrow(3, 234);       
      SetIndexBuffer(3, bearish);
      SetIndexStyle(1, DRAW_ARROW);// UP
      SetIndexArrow(1, 233);
      SetIndexBuffer(1, bullish2);
      SetIndexStyle(0, DRAW_ARROW);// DOWN
      SetIndexArrow(0, 234);       
      SetIndexBuffer(0, bearish2);
   }
   else if(Style==1){
      SetIndexStyle(2, DRAW_LINE);//UP
      SetIndexBuffer(2, bullish);
      SetIndexStyle(3, DRAW_LINE);// DOWN
      SetIndexBuffer(3, bearish);
      SetIndexStyle(1, DRAW_LINE);// UP
      SetIndexBuffer(1, bullish2);
      SetIndexStyle(0, DRAW_LINE);// DOWN
      SetIndexBuffer(0, bearish2);
   }
   return(0);
}

Anyone, please.
 
I'd really like to help you but indicators are Not my strong suit. It's the final chapter for me in The Book and I just started reading on indicators. Here's a suggestion in the mean-time try flipping the DRAW_ARROW with the DRAW_LINE and report back here if it draws line. Also, don't you need some form of Buffer ex)  SetIndexBuffer(1, bullish2[i]);
