FX Arbitrage Monitor

Triangular and multi-leg cycles across majors, net of fees.

Each card walks one loop. Type an amount of the starting currency and see, step by step, what you would hold after each conversion at the quoted price, the fee taken, and whether the quoted depth covers it. A positive net means the loop returns more than you started with.

Simulated mode uses generated prices and is for demonstration only. Live mode uses OANDA practice quotes. Profit uses top-of-book bid and ask only, before latency, slippage, and execution risk. Nothing here places trades or gives investment advice.
