The one thing–the only thing–that matters

Positive reinforcement word Discipline engrained in a rock

One of the problems with successful trading is that everything matters. In the scope of: when to get in, when to get out, how much to buy or sell, how often to adjust your position, etc., every decision matters. There’s no one thing that is most important. You can’t become a successful trader by focusing on entries or on position sizing–you have to have it all. (What’s the most important part of a submarine? You can have a power plant, a screw, a pressure hall, or a hatch. Pick one. Obviously this is not going to end well.) However, there really is only one thing that matters in the market, and it’s what you do: your actions are all that matters.

Orthopraxy is a term you may not have encountered before, but it’s easy to take apart: “ortho” meaning “correct”, and “praxy” meaning “practice”–doing the right thing. Though it’s a mouthful, the market rewards us for being orthopractical traders–for doing the right thing at the right time.

You can have all the belief, confidence, knowledge (all of this might be orthodoxy) in the world, but if you don’t do the right thing, none of it matters. If you’re paralyzed by fear, you lose. If you are excited and take positions too large when it feels right, you lose. If you ignore your exits and hold on, hoping for the best, you lose. If you are lazy and aren’t at the table when it matters, you lose. On the other hand, if you’re fearful, excited, bored, tired or whatever and you still do the right thing, then you have a chance.

This is why so many of the good and correct “trading sayings” focus on discipline and why so many successful traders say, over and over, with almost boring regularity, that you must have discipline to succeed in the markets. I invite you to take a few moments and review your trading history–both from a short term (recent weeks) and a longer-term (maybe the whole span of your career) perspective. Realize that the market does not care about your system or analysis. The market does not care how hard you work. The market does not care how passionately you believe if your own success. All that matters is you do the right thing at the right time.

This is very basic, but it’s also a profound truth. If you’re falling short on your executions, think about why, and think about what you’re going to do about it.
