So if you own a put contract with a delta of -. Say you own 10 contracts of XYZ calls, each with a delta of. To calculate position delta, multiply. This gives you a result of That means your call options are acting as a substitute for shares of the underlying stock.

Much of the time your option strategies will be more complex than a few call options with the same strike price. You might use multi-leg strategies, and you might even run different strategies on the same underlying stock at the same time. Each of those strategies might involve options with different strike prices and expiration dates. For example, you might wind up running an iron condor and a long calendar spread with calls simultaneously on the same underlying stock.

The deltas of some individual options in the complete option position will be positive and some will be negative. For instance, consider a long call spread with two legs. Example 2 shows the details of an XYZ long call spread with a long strike and a short strike, both with the same expiration date. The delta of the strike call is.

You pay margins when you short option. However STT on short option positions is quite high, so its advisable to close the trade yourself and not hold till expiry.

Many articles including wikipedia https: Why is it so? Rho is mainly with respect to Rate of change of underlying with changes in the interest rate. Check this — http: As mentioned in the above comments, while trading options it is advised to use Greeks and other parameters not really TA.

My doubt is that after TA only we can predict the direction and position according to the view. Option Greek will increase the success probability but TA will be the base.. Correct me if am wrong. Use TA to get a directional view…use that along with greeks to calibrate your trade. Do you have a strategy for getting monthly income through Nifty options,keeping in mind the market tank on 24Aug, are there any option strategy that will protect ones capital.

Sir, I have a doubt. For example, if i sell a lot at X premium price and waited till the expire day. I think the value of premium will approaches 0 or say some lesser value at the time if i bought a lot.

Yes, but to make sure X goes to 0, the security has to be below the strike in case of Call options and above the strike in case of PUT options. Hi Karthik bro, In Buy side, If premium on particular day lets say before 10 days or near to expire is more than settlement i. There is no guarantee that the option will remain ITM upon expiry. If you are a short term trader, better to book profits when you see it on the table! Yes you are right about Options, lots of possibilities with these instruments.

Yes you can hedge your future positions with Options. Buying 66 PE or 67 PE does not make much difference. Thank you so much for the lessons and really so easy to learn. I have one doubt. In first case decline is in negative value — and in second case decline is in positive value — , but both have same scenario. Thats because the delta is lower bound to 0…it cannot go lesser than 0.

If it was lesser than 0, it means the option is moving faster than the underlying, which is counter intuitive. Dear Karthik, I have some doubt , call trading in different value where as put trading in same value , why there is variation in call premium , can you explain this and how to calculate the value?

Could be different from market values. Deepak this whole module is dedicated towards helping people understand options trading. Suggest you go through this chapter by chapter. Fantastic easy to understand and involving explanation. I have many times tried to study and understand Option Geeks from many sites but the explanation is so boring that I leave it mid way and close the site.

The difference between other site topics and your is that to understand the other sites the reader has to be an expert but by reading your site explanation the reader becomes an expert. Just not clear why we should buy option2 and not option 1?

In option2 I will have to pay a higher premium and hence breakeven will be farther than in option 1 case?

Well, the Put option delta works the same way as the delta of a call, but in the reverse way.

So if spot moves up, the call option delta increases and the put option delta decreases. Of course the delta for each strike varies based on the moneyness of the option. So going by the example you have mention in this chapter. Hi Karthik, The content is very crisp and clear with very good examples and thank you for this work. I have one question over the Delta example you gave in the chapter. For the underlying movement of delta of 0.

So I as as a Option call buyer will need to pay less premium in case of choosing the 0. Am I missing something. The selection of Option should not really be dependent on the delta. Hence, I would not choose an option with 0. Modules are too good. The so called trainers should go through this module first before charging money Hats off to u sir.

Then why the option price divergence between 11th and 15th May ? Is anything I am missing? Your help is appreciated. Indicators are not absolute, I understand. In this case, gamma time variance could not have depleted so strongly as the contract is of far month. Yes, along with the greeks you also need to consider the overall market sentiment. This makes a difference. Vega depends on Volatility. Please check this chapter — http: With respect to your explanation of impact of Delta on premium.

Remember, the delta also showcases the probability of an option closing ITM. For example, if the delta is 0. So when a trader pays for a higher premium strike, he is looking for a brighter chances of closing ITM. Is my assumption is correct? Pl shed some light over it. Your understanding of delta values seems to be correct. The premium was when I bought the shares and the lot size was After 2 days the premiums rose to with the spot price at and I sell the contract.

That means I am selling my contract to someone else for the current premium price, if I sell the the contract before expiry. Hi kartik, i have a account with zerodha in the name of my momm. God bless u people. You can approximate the delta values yourself — check the delta table given the chapter.

Sorry for sounding so naive, i just want to be clear with the content. No, the premium cannot go -ve, if you see the Delta is capped between 0 and 1.

Also, remember, Delta is just one contributor to the premium, apart from this, there is also Vega and Theta which is contributing to the premium. Here the Strike price is This is for a Put option. Santosh, it works like this.
