Oinp proof of funds

[Effer]

I have six months to apply for the oinp starting June 27, that's when I received the noi.. i am planning to show the complete proof of funds as a fixed deposit. Is it ok? what other documents are required to be shown apart from the Fixed deposit statement issued by the bank? Do I have to keep the fd for a certain amount for time before I apply?? And if I show multiple fixed deposits in a month amounting to the required POF for one person can I apply the following month for the oinp or do I have to wait for the sixth month to apply?? Kindly help
