Edge vs luck: how to tell whether your last ten wins meant anything

Ten wins in a row feels like proof. Statistically, it is barely a whisper. If you are betting or trading positions that resolve close to a coin flip, a ten-run happens often enough that it should never be treated as evidence of skill on its own.

The only thing that separates edge from luck is whether your estimated probability was better calibrated than the price you paid. That is why every UniverseIQ analysis shows two numbers side by side: the AI probability of the outcome and the probability the market implied. The gap between them is the edge, and edge is the thing that compounds.

A useful discipline is to record the edge at the moment of entry, not the result afterwards. Results are noisy for hundreds of samples. Edge is measurable immediately. If your average entry edge is positive and your sizing is sane, the results eventually follow the math.

When you review your history, sort by edge rather than by profit. You will usually discover that your biggest wins came from your thinnest edges, which means they were closer to gambling than you remember, and your steady grind came from repeatable, unglamorous positions.

Rule of thumb: below roughly two hundred resolved positions, treat your win rate as an estimate with enormous error bars. Judge the process, size conservatively, and let the sample grow.
