Hello Edward, Yes I ran the code and it looks good. I see the extra
triangles you placed below the BUY arrows and on top of the SELL
arrows. Also I noticed the hollow white circles you placed on the
trades as well. Very interesting coding.
I am learning just how powerful amibroker can be. My assumption is
that if you can dream it, you can code it.
I noticed that the actual size of the original trade arrows remained
the same. I guess to enlarge the actual arrows involves quite a bit of
work.
How did you know to call the circles "hollow white circle"? Where can
I get the references to shapes (arrows, circles, triangles, etc)?
Thank you for the code. I will save it.
