To a well trained eye, to someone with lots of experience, a move up or down in price doesn't necessarily mean the trend will continue. You watch price action long enough and you'll be able to sniff out that BS tail end of a trend (the final shakeout) and fade or bottom fish those situations for the right reasons. You cant just tell this from looking at a chart, its all about getting down to the nitty gritty details. after a good deal of time, if you've spent your time wisely watching price move, you'll see why people fade/bottom fish.
