It does show on my chart when I load enough bars.

That's funny it doesn't show on mine. I could send you an image if I knew how to add it to this post.

I don't need an image, rather to know how many bars of data are you loading - if my reply wasn't enough of a hint ;)

To post an image, upload it first to any free image hoster (tinypic.com, imageshack.us, imagebam.com, imgur.com, thumbsnap.com - to name a few). Then:

* either retrieve the direct link to the full-size image and paste the link right between a pair of IMG tags (you should see a pane with "...LINK, QUOTE, CODE, IMG" buttons when adding a new post),
* or use a code snippet "for posting on the forums" (usually, every image hoster provides it).

Don't worry if things look broken - in this case, just leave the image link and we'll edit your message.
