Quote from NoDoji:
You never know if breakouts will fail or not, or if they occur because of news (by the time us low life retail traders know the news, price is far away), but by using TA/PA to get positioned properly, every now and then you're part of a move like that, which is a good reason to use soft profit targets on breakout trades (breaks of high/low of the day, breaks of narrow range consolidation, and triangle/channel breaks). Sure, sometimes the breakout fails and you exit with $0, but when the breakout is strong, you're not left looking at 20-30 ticks of profit while price keeps running.
