hi Wally, like Mike explained the shapes are built in. You can find all of them in the manual:

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. --- In amibroker@yahoogroups.com, "Edward Pottasch" <[EMAIL PROTECTED]> wrote: > > hi wally, > > maybe this example helps (below).
