Yours is arbitrary because it uses all candle wicks but one for the trendline. Either you do it by closes, or you do it by high/lows, not both.
Actually, not sure if that's a 'hard rule' of trendlines.
Anyway, the triangle looks fine to me. Broke out upwards. Don't know what porcupine's problem is with it... I think he just doubts that TA could ever dominate fundamentals, news, sentiment, etc.
If there is an actual glitch in the exchange data or it is due to some form of illiquidity (then again, you don't chart illiquid exchanges), then that's ok, but it's a bad idea to assume you can say which is valid and invalid, which is to be included and which ignored. It's the same thing with news, you don't have a framework of judging that, so might as well draw some dinosaurs.
