Risk discipline: linking this to psychology
Posted: Tue Oct 06, 2026 11:43 pm
For me, risk management and psychology are the same problem looked at from two sides. I design my risk rules on the assumption that my willpower will fail.
That sounds negative, but it is just what my journal shows. On calm days I follow rules easily. After two losses, or after a big winner, my judgment gets worse in predictable ways: bigger size, faster entries, less waiting for confirmation. Telling myself to "stay disciplined" does nothing at that point.
So the rules do the work instead:
- A ticket cap per session. When I hit it, I am done, no matter how I feel.
- A script that closes all positions at my daily loss limit. I do not have to decide anything.
- An earlier session end after a red morning. If I am down at 10:00, I stop at 11:00 instead of 12:00.
- No size increases on the same day as a big winner. Changes happen on Sunday.
Each of these exists because I broke the softer version of it at least once. The script came after a day when I kept moving my mental limit lower.
Psychology books helped me understand why I make these mistakes. The rules are what actually stop them.
