In this process, the maker-taker assumed a risk: in the profit-making cycle, the exchange ratio of the non-principal currency to the principal currency has been negatively changed, and the time required for the exchange back to the principal currency is held unknown. Maker-Taker provides a "Stop Loss" parameter for risk control to ensure that the risk of principal loss is manageable to the greatest extent. In a later version of this strategy, the team plans to deepen the hedging of turnover risk, including auto-triggered liquidity hedging.
