When there are a large number of option strikes and maturities, the human mind suffers from immense information overload. Nice displays of information are crucial for a mere mortal to be able to take in this information and turn it into good decisions. As David Gelernter might have said, beauty is the only defence against complexity.
Today NSE has released a sweet and simple display summarising data for options at all strike prices for one underlying at one expiration date. Click on any of the strikes for another slice on this data. Or if you want a more interesting example, here's Satyamcomp. I feel this display will be extremely valuable to anyone trading the option market. Suggestion to NSE: Why not have this page update in realtime without my hitting Apple-R?
