Different types of option greeks.

Delta.

1. Delta is one of the four option greeks and option greeks help us understand how our option positions are expected to perform relative to change in the environment. 
2. Option greeks delta is the directional risk management of an option and all that means is that delta tells us how much option price is expected to change relative to change in stock price.
3. Specifically, option delta tells us the expected price change of that option relative to a 1 points movement in the stock price.
4. Delta for a call option is +ve and delta for a put option is -ve
5. The maximum value of call delta is 1
6. The minimum value of call delta is 0.0
7. The maximum value of put delta is -1
8. The minimum value of put delta -0.0
9. So how do these values affect the selection of option strike?
10. let select two delta options 1st delta value Is 0.75 and 2nd delta value is 0.5
11. If stock price increase by 10. 1st delta value Is 0.75 option price will increase by 7.5
12. If stock price increase by 10. 2nd delta value Is 0.5 option price will increase by 5
13. So selection of delta is important to factor and we will upload these values every day in an excel sheet.
14. Chose the strike price with a delta of 1 so that you can gain maximum when a stock moves in your direction

6. Let say Gamma of 210 strikes with 14 days to expiration has 0.07 gamma value 
7. If the stock price moves 1 point delta will change by 0.07 
8. If the delta was 0.8 and the stock move 1 point new delta will be 0.87 
9. If delta increased it will also increase the total profit
10. If stock move 10 points and quantity is 1000 profit will be 8700
