The Order history section of the platform contains both filled and cancelled orders. To check if your orders have been successfully executed, you may head to your order history and check the status of your recent orders. Successful orders should be marked as “FILLED”.
Partially filled orders (for limit orders), on the other hand, would only appear on the Open Orders tab - since the order has not been completed yet - and Trade History tab - since this tab shows any executed trade.
