Is historical data adjusted for stock split and bonus

I refer to the stock 'TITAN Company". In the chart for BSE, the historical data prior to the stock split & bonus in 2006 is not back adjusted so it appears that the prices have crashed. However, for the NSE data this does not seem to be the case.

I am trying to understand whether this is how charts are generated and whether we need to analyse the reason for drop in price in BSE.


BSE charts aren’t adjusted for corporate actions, NSE charts are.

Thanks Bhuvanesh for your reply. Any reason for this? Are there any other exceptions to BSE data that users need to be aware of?
