+1. consider a JIT LP that has ETH and USDC both in a wallet and in a CEX. 
+2. when the LP observes a large ETH -> USDC swap in the mempool, they deploy a LP position on Uniswap, and at the same time submit an ETH buy order on the CEX. 
+3. after both trades, the LP has the same total amount of ETH and USDC as before.
