Hi
Thank you for asking this question.Markets exist in different Time Frames and we as investors should try to capture as much information about the market as we could.By Time frames I mean Markets exist Weekly,daily,intraday and tick by tick.An intraday chart will give clear picture about the rise or fall of the Market on a particular day than the End of day Price info Provided by Bhavcopy or Newspapers.We as a investor would like to know whether the rise happened is due to Global reasons or Our Market is inherently bullish(An End of day data will not reveal such information).For eg End of day data would be like this.
Date Open High Low Close Volume
20090720 14744.92 15209.04 14744.92 15191.01 35600
An end of day Price information will not be enough to capture the reason behind market rise or fall. An intraday chart will give a much bigger picture about market rise or fall.
