Triangle from classical technical analysis most likely is exotic idea, but this is a way how I see it ( I have developed my own method to analyse the market, based on classical technical analysis, but different). W-Formation perfectly fits and now, as you pointed, it looks even better!. But double top or double bottom is not on the screen (at least yet) as classical technical analysis suggest, I would not call it double bottom or top. Reason is, there was not any break yet, if we call it double top; and double bottom in the middle of the trend going up, does not really count by the classical technical analysis (as I know it according book by John MaGee & Robert D. Edwards).
Please tell me if I am wrong, I do believe you have better experience. I am open to learn.
I hope I have explained myself clear, as English is not my tongue language.
When everyone thinks alike, everyone is likely to be wrong....cheers...let´s keep it up...
