pub const CANCELLABLE_ORDER_STATUSES: &[OrderStatus];Expand description
Order statuses that are safe for cancellation queries.
These are statuses where an order is working on the venue but not already
in the process of being cancelled. Including PENDING_CANCEL in cancellation
filters can cause duplicate cancel attempts or incorrect open order counts.
Note: PENDING_UPDATE is included as orders being updated can typically still
be cancelled (update and cancel are independent operations on most venues).
