its real simple- either honor your stops, or lose a disproportinate amount to the gains you make from normal trades. if you blow a stop and become stubborn, it is very easy to turn a trade that costs 500 into one that can cost 5000 as you add size and convince yourself that you are right- trust me. My worst trade ever cost me -9000 on 4500 shares and after that, i studied it and my problem areas, vowing never to be a jackass and blow a stop like that again- it took me almost 2 weeks in this crappy market to make it back. never again, i said, and I am very vigilant on my stops now. drawdowns like that are unacceptable and i hated trading from a losing position knowing how badly i fucked up and how much i had to make back. i did it, but it wasn't fun and taught me a lesson.
anyways, the market does what it does, sometimes for strange reasons- as a trader you react to what it does, read the tape, make a decision. if you are concerned about being right all the time over making money and exercising the discipline of your system, you're fucked and might as well start flipping burgers at McD's. if you can remove emotion from your game, then you can act instinctively within the confines of your system and be consistently profitable. i know many traders who were good scalpers but would have a day where they gave back a month or more of profits becuase they:
were tired, hungover, mad, had outside events influence them, were being stubborn, were pissed off, whatever........
and then they proceeded to blow their stops as they blamed their losing trading on these influences. thats bullshit. look in the mirror- you and you alone are responsible for your actions in this business. you know what your rules are, what your system says you should do- you know that when you follow your system it has a positive expectancy and will produce consistent returns- why should it be that hard to follow it? what separates winning from losing traders is the ability to execute their systems without emotion, taking a loss when it hurts but they have to. if you get emotional in trading, it WILL cloud your judgement and will affect your reaction speed and money is made and lost very quickly.
so, ask yourself- would i rather be right or make money????
