Right isn't the point

Most of what a price does in a day is nothing. It ticks up a little, down a little, drifts inside the range it’s been drifting inside all week. Taleb has a rule of thumb for that, in Fooled by Randomness: unless a move is bigger than its usual daily swing, treat it as noise. Not a small move, not a boring move. Noise: indistinguishable from randomness, carrying no information at all.

Working hard at the wrong thing

Taleb writes about Nero, a (fictional, semi-autobiographical?) trader, who has a theory for why that matters more than it sounds: people who work hard at trading often do worse than people who think hard at it, because working hard usually means watching more, and watching more mostly means seeing more noise. Work ethics, in Nero’s words, “draw people to focus on noise rather than signal.” It’s also why counting how often you were right misses the story. “How frequent the profit is irrelevant,” Taleb writes, “it is the magnitude of the outcome that counts. Very few people take home a check linked to how often they are right or wrong. What they get is a profit or loss.” If most price moves are noise, most of the moments you felt right about them were never going to matter anyway, they were too small to be anything but chance. The moves worth reacting to are rare on purpose. That’s not the strategy missing opportunities. That’s the whole point of drawing the line where you drew it.

Mild success, wild success

Nero’s shorthand for the same asymmetry, a line he returns to twice: mild success is explainable by skill and labor. Wild success is attributable to variance. Steady discipline produces steady, unglamorous outperformance, because that’s what discipline is supposed to produce. A single spectacular result is usually just an extreme draw from that same variance. The skill story shows up afterward to explain it.

Aurono is built around the same asymmetry

Aurono’s ACB Guard runs on this exact principle: most of what the market does in a given week isn’t a reason to act. A strategy can sit blocked for weeks, no sells at all, because price hasn’t cleared what you paid for the position. I’ve written before about exactly this: weeks of nothing, then twelve days of eight trades once price actually crossed the line. Frequency near zero isn’t the strategy missing opportunities. It’s the strategy correctly recognizing that almost none of what happened along the way was worth reacting to.

Taleb built himself a threshold so he wouldn’t have to relearn, every single day, which moves were real. Aurono starts you with that threshold already drawn.
