Measurement-first harness for prediction-market arbitrage.
The disciplined taker crosses the spread only when a gap's net edge beats its fees. The line is cumulative P&L over time; each green dot is one booked trade. Click any dot to jump to that trade in the table below.
A token's price is the market's probability, so a more likely event should cost more. Threshold markets on the same asset and date form a ladder where a bigger move is always less likely than a smaller one, so the less likely rung should always be the cheaper one. When the market misprices this and the more likely rung is trading cheaper, we buy that rung and pair it against the other. The payout is locked no matter what, so the mispricing is risk-free profit. New to this? Read How it works.
Each row is a detected rung pair. TRADED rows are inversions whose edge beat the fees; expand one to see both rungs and the math.
