Contact the customer supports of your broker to get the detailed information. Every broker has different guidelines in activating swaps.

If your broker have this kind of feature, you may visit your client cabinet to know the details of swap account activation. I also agree with the previous comment that you must contact the customer service of your broker because they have the better answer than ours.

THe simple way is to ask the chat support of your broker. I cannot answer your question because I have no idea if we are using the same broker.
