hi pankaj,
i have found two problems-
1)the input sequence does contain del_percent column while converting from files and after rebulding from files.
the default format shuld be Symbol,date,open,high,low,close,volume,delivery-volume,delivery-percent
2) symbol for NIFTY is S&P cnx nifty but the symbol changing procedure is not accepting & character.
