first, I don't understand Russian (4 other languages yes, but no Russian) second when I analyse an optionpositions I never look at charts with different strike prices, certainly not ones with prices at expiration. I just look at my delta, gamma, theta, rho and vega over different strike prices.
But in Russia we have only two books with tarnslation. There are MC milan "MIllan about options" Tomset "TRading on options"
There's nothing to understand there, as the text in Russian doesn't provide any useful information. (I understand Russian)
Read those three books which I have mentioned, mcmillan is probably the least important one to really understand options and the concept of dynamically delta-neutral hedging.
it's not that much, everybody learns 4 at school in belgium, I have a brother who speaks 7 languages one of the best ways to learn a foreign language is to read a lot ...
I hope that you did not disappear from type. Really..I read about those books.They powerfully differ from that read i. Thank you for advise
