Is anyone good at fx options? I have a -30K position in AUDUSD which is now a bit underwater and I'm considering buying AUM calls or AUX puts. What I don't understand is all those multipliers and how many options I need to buy. Is it true that -30K position is 300 AUM index contracts? And as the options multiplier is 100 then 1 option is actually has 10K exposure and I need 3 options to have the same exposure as my FX position?
