Hello Sir,

What should I do if I want to change the symbol of the scrip which is already in the list. E.g. In India, on NSE exchange, symbol of HEROHONDA changed to HEROMOTOCO effective from 08-08-2011.
Now I tried to change it from bulk updater but it is not showing the change. What should I do?

Hi Vivek,

Today when I tried the same, it gave message "HEROMOTOCO" already exists and it did not change HEROHONDA to HEROMOTOCO.

This is because ticker symbol "HEROMOTOCO" already exists in your database.
Remove this symbol first.

How do I remove it? Also, if I remove, then I will have to download all the data for the last 16 days. Is it possible to only download just one symbol for a a given short period?

You have to download data from the date symbol changed up to today's date.
Best solution for this is to keep watch on symbol change on daily basis & keep updating the symbols as & when it happens.

I had found a simple logic method ghanshyam. remove the symbol from database. Then again add the same updated one
Create a new watchlist
add only this symbol to that watch list
Then update Intraday data by right clicking and selecting download data for all symbols (specify the number of past days as 15 (by default it may be 1)
