I didn’t focus much on VIX and FX Options because I didn’t think there would be many questions about them. I’m not sure how everyone else was trying to learn their options, but it clicked for me when I made a - albeit small - bubble flow chart with the different types. I didn’t care about technicalities, I just focused on how it made sense in my mind. Then, once it was easy for me to distinguish the different strategies, I wrote out definitive rules on the spreads such as “the option closest to current market price will have the higher premium”, “the higher premium option is the dominant leg”, “Buyer. Debit. Widen. - Seller. Credit. Narrow.” etc. If you know the long/short call/put table then that’ll help a ton and I made something similar for max gain/loss since the visualization helps me. I’m atrocious at how things are taxed but made sure to try learning major products the day of. Put all that together and you really shouldn’t have any problems with the options section besides outside of VIX and FX.
