And I have to highlight this error of thinking (sorry an) because trading for excitement is not a good place to be. I trade to earn and every trade has a price target set. None of my winners are exciting. Heck, I can't even remember last weeks winners.
It is a valid point that there are multiple exit strategies which I think was the OP's real question. Its an even more valid point that you don't enter a trade without a management strategy predetermined (worst case stop and exit plan). Examples of useful strategies include:
- limit exits at predetermined numbers from your entry
- limit exits at support or resistance (horizontal, channel, bands)
- limit exits at irrationally exuberant numbers
- trailing stops that trail 3.2 or some number of ATR behind the high or low of bars
- trailing stops behind retracement swings
- trailing stops that become tighter after some level of profit has been gained.
And then you can take a proportion of your profit at a number of points to ensure that a winning trade doesn't become a loser after a certain point while making sure you get exposure to big moves (I call this regret minimization). So you might take 1/3 at first restistance, trail stops at xxx, take another third at 2nd resistance, and trail the stop for the final third.
To all this you can add the possibility of adding to the position as it moves forward, either to replace targets taken or to pyramid the position.
All this is part of trade management (not money management which is about business like risk taking (not the stupid risks that merchant bankers the world around have taken with their customers money in an effort to line their pockets and discredit capitalism.
