excuse me if this is not the right thread to post my query.
I was going thru' the kolkata meet video and during ashish's presentation, he talked about value lines - some red and blue lines - sell below blue line/buy above blue line etc
I am curious to know what those blue lines were and how to plot them on a graph. I am attaching a snapshot of the graphs he showed during the meet. Also during those moments, he also talked about inflection points and then there was lot of noise in the video with many people talking simultaneously in the language I do not understand.
Can anyone explain me or point me to the post about what he discussed at that time?
