Greetings ! Soon I am going to post my observations on TCS. I am curious about your recommendation. Please bear with me as I have yet to grasp MACD. I am attracted to lines sketched by you. Let glance through Option chain (26th Mar Expiry). The maximum change in Call OI is at 1900CE. 12250 OI have been added and premium has moved up. Typically, an increase in OI along with an increase in premium is assumed as more "long" positions. The maximum change in Put OI is at 1550PE. Premium has declined. Possibly, this has caught your attention. Of course, there are other Put option prices where OI has increased but premiums have declined.
