soooo..... why even set your exit prices before each trade, if you will allow yourself to later change them? (after allowing the market to mess with you psychologicaly
The reason for selecting stops and likely initial targets in advance is that to preserve your overall edge you need to know if a potential setup meets your minimum risk:reward ratio. I may see an excellent setup and a price bar closes and signals a trade entry, but if the stop is $300 and the initial expected target is $280, I'll leave it alone.
Stops should be left alone or moved to break even if and when your rules indicate. My personal rules indicate leaving stops alone on with-trend trades and moving them to break even quickly on counter-trend trades. (I don't always follow the first part of that rule and it has cost me a lot in lost profits.)
Initial profit targets should be based on the most common price action that follows that particular setup. If you short a lower high, you should expect price to make a lower low and have an initial target somewhere below previous support. If price comes barreling toward your target, you'd be wise to move your target further or swing part of your position in case the market offers more.
Home runs should be the result of staying wisely-positioned as you trade. The way to do this is to trade with the trend, or off a solid trend reversal signal for counter-trend trades. By staying positioned with the trend you have a chance of riding a long trend, or being in a trade when a strong move in the trend transpires. For example, trend followers were well-positioned for May 6th's "flash crash", the home run of the year.
In trend following, it's usually safer to leave stops alone than to move them too quickly. Just yesterday I was positioned nicely with the new trend after a solid reversal signal was put in, moved my stop to break even when price moved $160 in my favor, got stopped out to the exact tick and then failed to re-enter the trade because I made the assumption that the price action was too choppy and range-bound. I stepped away and returned to find price was rapidly on its way to my initial $510 target and then it dropped another $300. That was clearly a home run on an instrument where I initially target $200-$400 profit per trade.
