Is there any way to set the Object_ Arrow of one indicatorBuffer to be drawn at the center of a candle?

Is there any way to set the Object_ Arrow of one indicatorBuffer to be drawn at the center of a candle?

I noticed that I cant set a Wingdings Object_Arrow of a indicatorBuffer to be drawn at the center of a candle by using SetIndex...Functions.

But I found that if I create a Wingdings Object_Arrow by ObjectCreate Function...then I can set it to be drawn at the center of a candle by using ObjectSetInterger Function with OBJPROP_TIME

for example: 

ObjectCreate(0,up_arrow,OBJ_ARROW,0,0,0,0,0);          // Create an arrow       ObjectSetInteger(0,up_arrow,OBJPROP_ARROWCODE,241);    // Set the arrow code       ObjectSetInteger(0,up_arrow,OBJPROP_TIME,time);        // Set time

Please help ! thanks in advance

merry Christmas & a happy new year!
