single chart which should contain Fibonacci Lines along with Candlestick charting with Darvas Boxesvolume-stk price indicator.
I do not have the idea about the splits and corrections for adjutments.Can u plz hlp me?
One more request for sharing(if u hv no problem) ur knowledge regarding how to Auto dwnld from NSE site and then auto update the quotes database present in Excel.
Hope nature blesses u both for ur good work.------joy_mitali

I really cannot help you on Excel and VBA scripts as I use OpenOffice and I am on Linux OS (No Windozzzzzzzzing for me)

I can point you towards AnalyzerXL. It is plugin or add-in for technical analysis in Excel. There are many tech indicators to work with. Try it out. You will like it. I haven't tried it though.

Also I have automated NSE bhav copy download in perl but not for excel.

Regards!

I am also in the process of modifying geniustrader (a perl based stock charting software) for online stock graphs. (This is purely for my personal needs)

I am aiming to provide an alternative to ***** quote service hence the need for info on splits etc.

Any idea where on NSE's website can we get information on splits & other adjustments? I looked around but couldn't find it.

Hi Swingtrader, Mitaly and Trader 9,
You all appear to be working on excellent ideas. During a visit to BSE, I spoke to their chief business officer but it is huge organisation and things would definetly improve, though teir BSEWEBX is doing well. I am a novice in trading fieldand my visit to BSE was in another context.
I am also facing problems in auto downloading as NSE server is not allowing auto downloader. ***** data servers are efficient and can be autodownloaded with programmes like amiquote and others but they provide the data next day and only for 200 days which may be insuffieint. If you study Metalib, you will get a fairly good idia of splittting and adjustment for bonus and devidend, etc. ***** also gives a good idea of it. Microsoft have also provided downloder for msn money central and stock analyser but Indian stock market is too small into their scheme of things.Excel is an excellent tool for querring and updating spreadsheets but a long and tedious process.
Can any one of you help in sharing your auto downloder tools or techniques. Though one would find it but it would be hit and run.
Thanks and regards.

To answer my own question - I found the place where splits & other adjustments are on nse's website. It is located under Corporates -> Corprates Action Search menu option. You will get to a page where if you select Ex-Date option and enter dates you will get the details of splits, bonuses etc.

Now comes the question - how to parse this data and adjust the historical data accordingly. I will give this a good thought and come up with robust logic. This will have to thought over and designed carefully because this has the potential to mess up the historical data if the logic is wrong

.

trader9 or anyone, let me know if you have any suggestions.

Thanks for the above info on splits and other adjustments.
I plan to start coding as soon as possible. I do have set up a free hosting site for the quote service.

Adjusting historical data will be straight forward keeping in mind the ex-date and the adjustment factor.

Anyways Thanks once again

I managed to parse the downloaded csv file to search for splits, bonuses, sub-
divisions etc.

I have attached the file containing the data.
Please check whether there is any mistake in the data as the list of Companies seems short.
I can then modify my scripts for adjustments.

Regards!

The list seems to be okay, it will only contain list of companies that went thru' splits/bonuses etc so it should be short. This is my opinion. Let me know if you run into problems. I will be going thru' the same exercise for my database today or tomorrow.
