Alright. Where do I start.
Firstly, calling a series of four descending candlesticks a "triangle" is inane. They have higher "volume" in the higher price ranges than the outlying ones, which if you try to visually expand that to a longer timescale, results in high fluctuation in volume, definitively busting any bear/bull/consolidation pennant. Furthermore trying to do so simply because there was a "breakout" at the end - which seems to be the only reason you've picked a triangle to retroactively label that period - is even more inane. There are a dozen models that would be more accurate in reading that scenario than trying to shoehorn it into this model. That could be a bearish abandoned baby back at $155.5, which would mean the price was going to fall sharply after slowing. That could be another one, at the $165 peak - and in fact it is almost.
TA is an adjunct to knowledge of the market conditions. The only thing that explains (IMO) that rise is bullish sentiment. Most all of the technicals pointed to a drop.
here's another example of a robust, micro-scale (triangle-within-a-) triangle:
-===-
-===-
how about 21 candles?
in all seriousness, while i do understand the point about the validity of other pattern assessments, i don't quite follow what you mean by comparing the volume in the higher price ranges to the outlying ones. maybe you can clarify?
i think that you misunderstood my intent in 'shoehorning' the pattern into this model. as you can see, i really love triangles.
i think nested triangles are beautiful, and you have to admit that the 21-candle resolution shows a robust triangle shape. i don't even have to draw the lines.
coming back to your point, what's useful about candlestick analysis is that it gives directional bias: you have a 'bearish' abandoned baby or a 'bullish' engulfing shape. triangles tend not to do this. only certain specific market conditions, like consolidation after a large drop, have directional bias -- that's where the 'bearish pennant' comes from, i'm sure you know already.
keeping this in mind, my intent was more to point out a triangle than to determinate the breakout direction. it is a 'weak' pennant, but it is a robust triangle. and triangles are useful to identify even when you have no idea in which direction they will break out because the breakout is a signal. if you can determine a time frame during which the breakout must occur, when you see the sudden volume, you receive the directional signal well before the movement out of the range.
i hope this makes my above posts seem less inane
