No one has given a clear solution for you but I went through this shit inside out so I'll save some hassle for you with bittersweet news.
Simple answer is that no one knows. Very few may know if they understand SPAN calculator offered by the CME exchange, but it's quite complicated because there are too many variables. How far is your strike price? Expiration date? What is delta? How volatile the market is according to CME? How much more margin requirement does your broker wanna add as insurance? And good luck finding that out; brokers consider their own internal marginal requirement a proprietary information so they will never tell you. They will simply say try to order it and it will give you how much your margin will be impacted before you confirm the trade order.
Also, a weekly expiration may be dangerous in volatile market as well as where your strike price relative to the market. There is a reason why few play this game, even if it can be a good idea. It is very capital intensive and if you buy straight call/put have fun dealing with theta decay.
In general, I would not recommend flirting with option contracts unless you really know what you're doing or you are being advised by someone who has solid track record of doing it IRL. Leveraged complex securities can be quite punishing to people who donno what they are doing because just as potential profits are highly pronounced, so is the mistakes/losses.
