Meghmani - trying to read the charts. Feedback requested

Meghmani being a fundamentally strong company saw a drop of some 12% in past 4 trading sessions. I am a beginner in reading charts. I have tried to plot my understanding of the chart and basis that have asked a couple of question on triangle formation and neck and shoulder formation.
It would be of great help if someone guides me on whether my analysis/ observation is correct or not.
