Relationship between Delta, Options and Futures

"Relationship between Delta, Options and Futures Investors spend a lot of time thinking of ways that they can mitigate risk while still earning money. Are you wondering how do they do it? For that let's understand a few things: Option Greeks measure how the option value changes in various variables like market price, interest rates, volatility and time to expiry. As we learned in the previous module, A futures contract allows you to buy or sell an underlying stock or index at a preset price for delivery on a future date. 

Options are of two types -- call and put. A call option gives a buyer the right to purchase an underlying stock or index at a preset price during a contract’s liquid life -- a month or also week in case of Bank Nifty. Delta is an Option Greek that captures the effect of the direction of the market. Call option delta varies between 0 and 1, some traders prefer to use 0 to 100.
