A Market Profile chart organises the session into a horizontal histogram. Time spent at each price is plotted sideways, so accepted prices appear wide and rejected prices appear narrow.
The wide area is the Value Area, where roughly 70% of the session trade occurred. The single price with the most time is the Point of Control, and the edges of the profile show where price was rejected.
Standard candlesticks show price over time. Market Profile shows the same session as structure, helping you distinguish balance from imbalance across Nifty, BankNifty, Sensex, Bankex, and individual stocks.
