QueryOpenOrders

Documentation from the Kucoin API page

Any order on the exchange order book is in active status. Orders removed from the order book will be marked with done status. After an order becomes done, there may be a few milliseconds latency before it’s fully settled.

You can check the orders in any status. If the status parameter is not specified, orders of done status will be returned by default.

When you query orders in active status, there is no time limit. However, when you query orders in done status, the start and end time range cannot exceed 7* 24 hours. An error will occur if the specified time window exceeds the range.

If you specify the end time only, the system will automatically calculate the start time as end time minus 7*24 hours, and vice versa.

The history for cancelled orders is only kept for one month. You will not be able to query for cancelled orders that have happened more than a month ago.
