How to draw a BIG arrow on the chart?

Hi all,

I have a question about using MQL4 to draw a big arrow on the cart.

I tried to set the width by by the SetIndexStyle() function, but it doesn't work.

Any idea? Thanks.

SetIndexStyle() is limited to 1to5(See helpfile),
Suggestion:
Maybe you could draw your arrow with line instead.
You use 7 line and you use the width you like for the line...

Thanks.

Actually I know that, but it doesn't work. That's very strange...

However, I figure out a simple way to solve it:

Not to use the SetIndexStyle(), instead, directly set it with the property...

#property indicator_width1 5
#property indicator_style1 STYLE_SOLID
