Abhijit Phatak been studying and trading on the basis of charts since 2003-2004.
He has developed a unique method of identifying what the market is upto, on the basis of charts of Options, and also straddles, OI of options, and Put-Call ratio at various strike prices. He has observed on many occasions how options charts have a different story to tell, sometimes exactly opposite to what the chart of the underlying is showing.
The momentum of a trend in the indices can also be identified on the basis of charts of a bunch of straddles. Almost all the techniques have been developed on his own by observing them over the years and many of the techniques that he uses are not found in any textbook of technical analysis.
He conducts sessions on his observations that have been well received by participants.
