ascending triangle, page-5

Cortis,
here's a link to a site that explains a lot of patterns. I'm trying to figure it all out myself. seems to me an ascending triangle is when an SP has a high it can't get past (like 12c with MPO) but each time it retreats it has a higher low. More often than not it ends with a breakout to the upside. I would be happy for any gurus to correct me or elaborate.
