Delta & Gamma Hedging Option Spreads using R

preview_player
Показать описание
We create a function that will take two options as parameters & then make calculations and generate a data frame with the results (Profit & Loss) of the given option spread by hedging gamma and delta. This is not a "profit" making strategy, it is mostly used by market makers who take the opposite side of your option trades.

Excellent video, thanks a lot.. I have one doubt.. Is it possible to neutralize Gamma of a portfolio, using only SPY? In other words, how to calculate total Gamma of a portfolio, like we do with Delta-Beta (weighted Delta or Delta Dollars). Or in case of Gamma is only possible to neutralize individualy per underline position? What about Vega?

so the market makers are not in it to make money? by eliminating delta and gamma risk, they
make the money on the IV they sell to the market
