Broadening Formation / Expanding Triangle / Megaphone / "BHOPU" pattern

Is is a triangle chart pattern where you will see the formation of higher highs and lower lows. On chart, the pattern looks like the reverse of a symmetrical triangle pattern. It is also referred as broadening formation or megaphone pattern.

Below is the Nifty Futures chart, just check out how many expanding triangle patterns we have seen in trading recently.
Broadening Formation Expanding Triangle Megaphone
Above are a few I could easily identify. With so many "false" breakouts and breakdowns during intraday and positional trades, you will know the reason why trading has been tough for the past few days.

I see many bloggers/websites mentioning about this pattern. But I doubt if anyone can really trade or identify this formation. People recognize this pattern only after it has done the damage!. Hindsight analysis is always I have done above!

Cheers :(

    I posted a symmetrical triangle out of the same chart(but 60 min).Guess its all our bias that makes us see what we want to see.

    hi, thank you for suggestion.I tried that before, but the "blog list" gadget modifies the url to .May be because it uses rss to update the "blog roll". I suspect ojn has disabled it's feed. This problem started after mok went for a break. OJN team member could help maybe...
