When you create a strategy on the spot market without Take profit or Stop loss, it will be instantly shown as "Completed", given that the order is market, not limit. It was made like this due to the characteristics of the spot market. There is no such thing as "opened position", because you buy real assets and keep them in your wallet. However, when Keep My Position Open (Spot exchange only) is enabled, the feature will monitor the strategy on the spot market even if the Take profit or Stop loss are not set. Therefore the strategy will not be changed to "Completed" straight after the opening.
