An asynchronous object-oriented program to simulate constant product AMM LP position on OKEx. An LP position that satisfies x*y=k is equivalent to an infinite grid trading bot. It sells spot when the price rises and buys spot when the price drops, passively by the help of traders and arbitrageurs. LP on a DEX earns trading fees and liquidity mining rewards. The trading fees are subject to the fee rate, the volume on the trading pair and the share of pool. On the other hand, a copy of LP on CEX doesn't earn trading fees. It costs trading fees to mimic the LP on CEX. However, it generates profit by selling high and buying low. The APR is purely the result of price action and can be used to deduce the realized volatility.

Chinese and English support, completed with annotations and docstrings.
