# update local orders, 前面有更新模块，与这边不完全相同，尤其是有成交的情况下，必须要更新
# 是这样吗？ 似乎也不是的，有成交的情况下，下一次订单也会让 set（local） - set（order book）=0的，集合相减的特殊之处
# 如果这样就没有必要了。
# 是这样简单的复制更新，还是本地自己维护一个 id list 好呢？ 也就是把（1）确定成交的从 local 删除；
# （2）确定提交的add 到本地；
# 缩进到循环： if len(completed_orders) > 0：，在出现两者不一致的时候，同步更新订单；
# 但是这个会导致一个问题，就是初始化的订单里，有price 为0，导致两者不一致的情况，怎么办？这里解决了，是通过 order id对比而不是
# 直接的 order 对比，所以应该是解决了才对
# 默认有3秒的刷新周期，导致被成功取消的订单，不会马上出现在order_book_manager
# 导致 local 比真实的多了，使得取消的订单在下一次被误认为是成交了
# 以上虽然 while 循环了，但是如果 while 循环的时候，有订单被成交了，这个订单就会丢掉，被误认为是撤销的订单了

# update local orders, 前面有更新模块，与这边不完全相同，尤其是有成交的情况下，必须要更新
# 是这样吗？ 似乎也不是的，有成交的情况下，下一次订单也会让 set（local） - set（order book）=0的，集合相减的特殊之处
# 如果这样就没有必要了。
# 是这样简单的复制更新，还是本地自己维护一个 id list 好呢？ 也就是把（1）确定成交的从 local 删除；
# （2）确定提交的add 到本地；
# 缩进到循环： if len(completed_orders) > 0：，在出现两者不一致的时候，同步更新订单；
# 但是这个会导致一个问题，就是初始化的订单里，有price 为0，导致两者不一致的情况，怎么办？这里解决了，是通过 order id对比而不是
# 直接的 order 对比，所以应该是解决了才对
