The Queue Was the Arbitrage: What 147 Days of Tick-Size Asymmetry Were Worth

For 147 days two of the largest USDC/USDT venues quoted the same asset on price grids differing tenfold, with zero fees on both. The cross-venue gap was there 41% of the time — and was worth almost nothing.

Now posted as a working paper on SSRN.

How Much Money Fits Inside a Depeg? A Census of 1,136 Stablecoin Dislocations

Nobody had published a systematic measurement of capacity during stablecoin dislocations. Two years of tick data, a reproducible event definition, a per-event capacity distribution spanning four orders of magnitude — and the finding that 97% of the money flows through the slow events, not the millisecond wicks. Now posted as a working paper on SSRN.

The Kelly Criterion Said Bet 3,000x. The Interesting Part Is Why It's Wrong.

Log-growth sizing applied to a live trading book: why the naive answer is a data-completeness alarm, why the formula's decisive input is unobservable, and the three situations where Kelly earns its seat back.

Why "Backtest Says It Works" Isn't Enough — An Independent Model Review Case Study

How a plausible-looking trading rule was pressure-tested: selection bias, regime decomposition, out-of-sample splits, PBO overfitting checks, and measuring real fill slippage instead of assuming it.
