Quote from optioncoach:
ToS gives the dollar value of the greeks which can be confusing. Think of it this way. You have a 510 Call in the analyzer. The price slices give the greeks for the call at different prices whereever you put the slices. Under Mode, you can click on LIVE where it will show the current price of the underlying. You can also move one of the red dotted lines to the strike of 510 to get the current greeks of the position at that stock price.
Now to get the actual greeks divide the dollar value by $100 and then by number of contracts. So at $540 where one of the slices are and close to where the stock price is now ($545). $68.18 is the dollar delta value so divided by 100 the delta is .68 at $540 underlying price.
So to make sure I am not confusing you, first step is divide by $100 per contract to convert dollar value of greeks to actual greek values.
Click on the LOCK word under MODE on the slices and turn it back to live and all 3 will move the vertical dotted red lines to the current price of the stock and give the current greeks of your call.
Ok on the main graph, the green line is the expiration risk/reward profile and the white line is the risk/reward profile for today. In between the white and green lines is the decay that will take the position to its max profit or loss.
As you change the strike price in the bottom simulated section you can see the changes in the risk profile and dollar greeks and the changes in sensitivities. Remember to unclick the lock next to the price of the option you are looking at as that will ensure it lists the current price to buy or sell and does not freeze the price at the $53.60 you have there.
Get familiar with this page as we can use it next to look at decay in your position. This analyzer is the best tool to understand the greeks. After just a week playing with this you got what you need to know to move into strategies.
Hi Coach, thanks very much for the explanation, I really appreciate it. I understand how to work the screen now, however have the below questions:
Q1: The greeks from the analyzer screen are diff from the Trade screen. Using GOOG $560 as strike price, the delta from the Trade screen shows .45 (please see attached), I then plugged $560 into the analyzer, it shows the delta is .5375?(please see attached).
Q2: What parameters am I looking for when considering risk/reward? would you give an actual example, so I can apply it to others.
Q3: I now know how to work the analyze screen but don't understand how this relates to actual trades?
Q4: GOOG gamma is pretty much all zeros from the Trade screen?
