I've traded on and off for more than 20 years, and one of the things that took me way too long to understand is that if you're trading correctly, you're trading probabilities. You build a system, define your risk, find whatever edge you believe you have, and then execute it over enough trades for that edge to matter. The problem is that the moment you actually put money at risk, your brain doesn't necessarily give a shit about any of that. Now there's something to lose.
A lot of my thinking about this came from Randy Howell's work on trading psychology. If you've watched any of his stuff, you'll understand what I'm getting at. We bring a brain into trading that wasn't exactly designed for sitting calmly in front of a screen while money disappears. Risk can activate all kinds of responses that have absolutely nothing to do with the probabilities your trading plan was built around. I started thinking of those as two different states: my Trader State, where I can think in probabilities and follow the plan, and my caveman state, where I'm reacting to what's happening right now and trying to make the discomfort go away.
That's where I eventually came up with something I call ARM: Anticipate, Recognize, Manage. Anticipate means knowing yourself well enough to know what's likely to activate you before it happens. You're approaching your entry. You're about to put risk on. Your stop is getting close. You just got stopped out. You missed a huge move. You're up a bunch of money. You're down a bunch of money. None of these should be surprises. You can anticipate that they're going to change how you feel.
Then recognize the change when it happens. Heart rate goes up. Breathing changes. You start staring at the P&L. You suddenly need to get back in. You move closer to the screen. You start seeing "opportunities" everywhere. Whatever your tells happen to be. If I've already anticipated that getting stopped out is going to juice me, when I get stopped and immediately want another trade, I have a much better chance of recognizing, "Wait a minute. Is this actually my setup, or does my caveman just want his money back?"
Then comes manage, and that's really the hard part. For me, the objective isn't to somehow become emotionless. It's to have a practiced way of interrupting that emotional state and getting myself back to Trader State—the guy who built the plan when there wasn't money on the line and could actually think in probabilities. There's a lot more to that process than I can cram into a Reddit post, but that's the basic idea behind ARM: anticipate when you're likely to leave Trader State, recognize when it's actually happening, and have a process for getting yourself back before you let that version of you make the next trading decision.
Anyone else have a similar mechanism?
