Triangular Arbitrage

Every A → B → C → A cycle in the selected universe, scored as R_A→B × R_B→C × R_C→A and ranked by net return: the fee on every leg, plus half of each pair's assumed bid/ask spread when the source only publishes mid rates.

Daily mid-market reference rates, published as one table per base currency. Those tables don't fully agree with each other, so positive cycles here are data artifacts.

Mid vs executable. A real loop buys at the ask and sells at the bid on every leg. Bid/ask sources price that directly; for mid-rate sources the spread model above is an estimate of it, not a quote you can fill.

Single-source mids cancel out. Cross rates from one consistent table multiply back to 1. Anything a mid source ranks above zero is a rounding or staleness gap in that provider's data, not an order you can fill.
