Changing Arrow Sizes in Custom Indicators

 
I wanted to know how to change the size of the arrows...for example, here is my code to draw a BUY arrow on the chart..

   SetIndexStyle(0,DRAW_ARROW);
   SetIndexArrow(0,108);
   SetIndexBuffer(0,ExtMapBuffer1);
   SetIndexLabel(0,"BUY");
   SetIndexEmptyValue(0,0.0);
See the GIF attached..(small red and violet circles)..How do I change the size of the arrow symbol? As of now, it appears too small...

 
Change width in the colors list
 
Dear Stringo,

Thanks! Works like a charm! :)

How do I add text label next to the arrow symbol on the chart? For Example, adding "BUY" next to every BlueViolet dot and "SELL" next to every Red dot...

There is impossible because text object anchored with top-center point.
