1. How do we interpret the volatality of options market? i think, OI indicate the liquidity in the market. waht kinda thumb rule do traders normally use to weigh the market.
To keep it simple, use the VIX number published at NSE site. Check out the historical graph of VIX data.. and on relative terms, u will be able to tell if current VIX i.e. current option volatility is high or low.
I laugh when now-a-day people say that we are in volatile mkt. When VIX is between 20 to 25 which is on the lower side of the range, we are in most relaxed, smooth flowing market. Infact that is warning sign that people are complecent. And when fear comes in mkt, VIX starts going up. Thats when option premium also starts going up cause people run for hedging when they are woken up from the complecency..
2. How delta is measured.. can we get the delta from NIFTY or any where. ?
I am writing some thumb rules of Option Delta here, Hope this helps..
- Delta is measure of Change in Option Premium wrt to one Unit move of Underlying.
- Calls have +ive delta, and Puts have -ive delta
- ITM option have higher Delta. Deeper the ITM, higher the delta.
- ATM options have delta approx around 0.5
- Roughly, Delta indicates the probability of option expiring ITM. This justifies the higher Delta of deep ITM options cause they their delta of 0.92 indicates that 92% of chance, they will remain ITM.
- Futures / Stocks have Delta of +1 i.e. 1 Rs move in stock price will result in change in futures value by appox 1 Rs (give and take minor adjustment).
You will need option analysis tool to find out about the delta or other option greeks.
3. technical analysis gives some Resistance and Support level to the index.. sometimes ppl claims its there at a strong support or not going to break the strong resistance. How do ppl claim that... does it help in options trading strategies?
Tech Analysis is foundation of any trading. That will help u understand what mkt is doing now and what it may do next based on historical patterns. That gives edge to option trader in terms of selecting right option strategy for what is going to come next..
In TA there are guiding rules which helps in identifying the relative strength of a price level, trend line etc. Knowledge of these levels certainly helps in designing option strategy.
Say if there is strong support at 4920, i.e. whenever mkt came here, buyers came in and price could not go below that. So if I have to write a PUT, then it is safer to write 4900 put which has higher chance of expiring worthless.. then writing 5000 PUT which might end up ITM later.
Similarly, 5200 was strong resistance, cause price fell from that in last 3-4 occasion so that was a safer strike to write calls.
But these strong levels also starts getting weaker with each touch of price.. (like a strong wall may not fall by first hit of hammer but with few more strikes it eventually falls down).
4. options trading is more abt anticipating the nifty swings, what r the indicators which traders follow.. to anticipate a swing in the Index... global Sentiments ?
You can use different approaches to anticipate what is going to come next. I trust charts more then anything so I use that data (along with other mkt data published by exchange) to form my opinion about what is going to come next. In my view, you can't monitor global sentiments cause they are unlimited.. so better to focus on our energy which is manageable and form our analysis.
Lets accept the fact, that you can never be 100% perfect in your analysis.. even if you have the capabilities of search engine of Google to scan the world news. So plan our risk well, and learn to live with <100% analysis. How much less ? it is individuals choice.
My suggestions will be to use technical analysis to read the mkt. For option, Time is crucial factor hence, IMO, all the stuff of fundamental analysis, great mgmt of company etc is of no use in options trading.
Hope this helps.
Happy Trading
