- RequestTimeoutについての説明
85
-
86
- This exception is raised when the connection with the exchange fails or data is not fully received in a specified amount of time. This is controlled by the timeout option. When a RequestTimeout is raised, the user doesn't know the outcome of a request (whether it was accepted by the exchange server or not).
87
-
88
- Thus it's advised to handle this type of exception in the following manner:
89
-
90
- for fetching requests it is safe to retry the call
91
- for a request to cancelOrder a user is required to retry the same call the second time. If instead of a retry a user calls a fetchOrder, fetchOrders, fetchOpenOrders or fetchClosedOrders right away without a retry to call cancelOrder, this may cause the .orders cache to fall out of sync. A subsequent retry to cancelOrder will return one of the following possible results:
92
- a request is completed successfully, meaning the order has been properly canceled now
93
- an OrderNotFound exception is raised, which means the order was either already canceled on the first attempt or has been executed (filled and closed) in the meantime between the two attempts. Note, that the order will still have an 'open' status in the .orders cache. To determine the actual order status you'll need to call fetchOrder to update the cache properly (where available from the exchange). If the fetchOrder method is 'emulated' the ccxt library will mark the order as 'closed'. The user has to call fetchBalance and set the order status to 'canceled' manually if the balance hasn't changed (a trade didn't not occur).
94
-
95
- **今回エラーが出ているcreateorderのtimeoutにおける２つの対応推奨案**
96
-
97
- if a request to createOrder fails with a RequestTimeout the user should:
98
- update the .orders cache with a call to fetchOrders, fetchOpenOrders, fetchClosedOrders to check if the request to place the order has succeeded and the order is now open
99
- if the order is not 'open' the user should fetchBalance to check if the balance has changed since the order was created on the first run and then was filled and closed by the time of the second check. Note that fetchBalance relies on the .orders cache for balance inference and thus should only be called after updating the cache!

  This exception is raised when the connection with the exchange fails or data is not fully received in a specified amount of time. This is controlled by the timeout option. When a RequestTimeout is raised, the user doesn't know the outcome of a request (whether it was accepted by the exchange server or not).

  for a request to cancelOrder a user is required to retry the same call the second time. If instead of a retry a user calls a fetchOrder, fetchOrders, fetchOpenOrders or fetchClosedOrders right away without a retry to call cancelOrder, this may cause the .orders cache to fall out of sync. A subsequent retry to cancelOrder will return one of the following possible results:
41
40
  a request is completed successfully, meaning the order has been properly canceled now
42
41
  an OrderNotFound exception is raised, which means the order was either already canceled on the first attempt or has been executed (filled and closed) in the meantime between the two attempts. Note, that the order will still have an 'open' status in the .orders cache. To determine the actual order status you'll need to call fetchOrder to update the cache properly (where available from the exchange). If the fetchOrder method is 'emulated' the ccxt library will mark the order as 'closed'. The user has to call fetchBalance and set the order status to 'canceled' manually if the balance hasn't changed (a trade didn't not occur).

  if a request to createOrder fails with a RequestTimeout the user should:
44
46
  update the .orders cache with a call to fetchOrders, fetchOpenOrders, fetchClosedOrders to check if the request to place the order has succeeded and the order is now open
45
47
  if the order is not 'open' the user should fetchBalance to check if the balance has changed since the order was created on the first run and then was filled and closed by the time of the second check. Note that fetchBalance relies on the .orders cache for balance inference and thus should only be called after updating the cache!
