Arbitrage / Dutching Calculator
An arb exists only when the inverse of both decimals sums to less than 1. Execution, limits, and timing usually erase theoretical profit.
Formula
Arb if 1/d1 + 1/d2 < 1. Stake i = bankroll × (1/di) / sum(1/d).
Worked examples
+150 and +150. Inverse sum is 0.80, so a theoretical arb exists.
FAQ
Is arb guaranteed money?
No. Limits, voids, and latency can turn a quoted arb into a loss.
