Question about Charting and Wedges

Guys,
I have a question, I noticed this when i was updating my ongoing TA with LTC. Am I crazy or does this symmetrical wedge look like it is tightening up into a new wedge? Does this have a formal name? is this even relevant?

Additional newby question, is it best to always use the highs and lows or the opens and closes? I have noticed that the big orders or the manipulation by whales on stop losses can sometimes cause a large spike that may not be indicative of the overall pattern. Thoughts? Thanks for the advice in advance!
