I just want to point out the update I just posted an hour ago could go in a lot of different ways, depending on which wave is extended. Right now I'm GUESSING that it's going to form a first wave extension based on the size of wave 1 but there is really no way of knowing for sure which type of impulse could form because the correction preceding it was a common flat which doesn't really tell us much about the implications of future price action, and this could potentially go much higher if it were to form a 3rd or 5th wave extension, so for now we'll just have to see how it develops. If this ends up being a 3rd or 5th wave extension then we could go as high as 855.
It's interesting to note that if the first wave extension did play out then we'd probably form a nearly perfect double top on the daily chart and possibly even a nice little bull trap by moving just a few ticks above the June high. Also since this is likely to break the top of wave-a it means that it will probably form an irregular failure in the longer term which is more bullish than a c-failure.
For now, we'll just have to see how this develops before taking any long-term positions, but the overall count I have published here seems to still work I just tried to call the top a bit early.
