This is the arbitrage constructed from four gold futures contracts, all denominated in USD. The four contracts include: CME's GC contract, NYSELIFFE's ZG and YG contracts, and the HKFE-listed GLD contract (not to be confused with the US-listed ETF of the same symbol).
The similarities of these contracts make this structure a relatively simple one, however if the many contracts listed in other currencies, with different quality grades and weights of varying sizes are included, the complexity of arbitrage grows exponentially.
