When I traded stock, the flag pattern was my favorite setup. So much so that when my future ex-wife offered to knit a sweater for me I had her embroider a flag pattern. Maybe it's not the most stylish sweater around, but it makes for a good conversation piece!!
Your main concern should be if the flag pattern will work or not. Now, I can tell you that it is the most dependable of all chart patterns IMHO, but, of course, provided that it is an actual flag and not some way out on the limb price movement that someone
imagines to be
a flag. And from what I've seen, that makes up the vast majority of the cases.
Patterns develop according to changes in supply and demand. They need not be created deliberately. And, according to your question, if you think people who exit during a flag are dumb, remember that 99.9% of traders and investors can't recognize even a picture perfect flag pattern, or any other pattern for that matter!
