Quote from jrs3:
Flags are flags, charting is more of an art form than a science no pun intended.
I fundamentally disagree, no pun intended.
Charting is, for the most part, about direction, support, and resistance.
Support and resistance is displayed by places price wants to go or does not want to go. You can't "cross" a price bar through a trendline, saying that's support or resistance, that is paradox. If you want to have a valid channel, it has to orient itself on the outer most part of the range, and in a way that fits both sides.
Art? I don't know about that. I've been in the art industry, I still am a designer and have an art business. I design and paint and make music, you name it. I've read hundreds of books on art. My girlfriend is an artist. I have art all over my house. I've even created crazy "chart art". Downstairs, I have an entire room covered in charts. But when it comes down to it, I don't think charting is really art. I so wish it was, but I'm afraid it just isnt'. Charting is pretty dry stuff, down to logics and probabilities. Just ask some friend to look at your screen and ask him if he thinks it's art!
Seriously though. I'm not saying this out of mere opinion, but because I've backtested a myriad of ways to chart things, particularly retracements, trendlines and channels. There are ways of doing it that are statistically more reliable than others. Those are the ways that work best...
But of course it's up to you to do your own backtest. Do whatever works for you. I won't ague.
Hope you did well on your long!
