Trading is ALL about managing risk and probability. The risk part is easy, you can quantify your risk by setting a stop on all your trades. Yes, a stock can gap through your stop overnight, so we can’t know are risk 100% for certain, but setting aside major overnight announcements and earnings, we can get a pretty good idea. The probability part is a little more difficult. I don’t have empirical evidence to support the patterns I trade on both the long and shorts side, other’s have done a decent amount of research, and I have read some, but at the end of the day I have always believed that so called voodoo of technical analysis is a different religion for everyone. Technical analysis, being little more than the study of the psychology of the market, is interpreted by everyone differently, and therefore should not be seen quantitatively to a large extent, but as more of an art. It’s just like a psychologist, you can go to 4 different guys and get 4 different answer to your issues, they will approach you in different ways, ask you different questions, it’s a feel thing.
Anyway, I want to make the point in this post that you’ve got to understand and accept the risk you are putting on when you make a trade. I will review a trade of mine where I made a terrible mistake and foresake this principal, and it has cost me quite a good deal of profits over the last few weeks, especially give that my thesis was correct. It’s not enough to have good ideas, you must execute them properly.
