I wrote a strategy for 2021-2021.12 that worked perfectly. But when I reviewed it in 2020.9-2021.12 the yield curve suddenly stopped moving around November, I saw that the next log was still holding at this time, why did the yield curve stop moving? I thought it might be because the okex exchange maintained during this time?
