Arbitrage with bounded Liquidity

By: Christoph Schlegel

Potential Business Impact:

Makes trading between markets more profitable.

The arbitrage gains or, equivalently, Loss Versus Rebalacing (LVR) for arbitrage between two imperfectly liquid markets is derived. To derive the LVR, I assume a quadratic trading cost to model the cost of trading on the more liquid exchange and discuss to which situations my model arguably applies well (long tail CEX-DEX arbitrage, DEX-DEX arbitrage) and to which not so well (CEX-DEX arbitrage for major pairs). I discuss extension to other cost functions and directions for future research.
