this is the site... kindly put "HINDLEVER" in the text box ( sample script)
and hit "plot" button..
then you shall see the chart....
Now, I want to extract these various price and time data to excel spreadsheet.
I am just a begginer programmer.
I just managed to decompile the interfaces ( the jar files you know..)
but then.. i dont know what to do.
should i connect to server ( if so.. how?!!? )
or should i use the data that is downloaded to the client ( my desktop)
.. and i suppose it is not stored in any file as such...
i think it is stored in some memory address or something volatile..
please do help me to get that data.... in ANY way that works!
thanks giving time to read this,
thanks in advance for the thinking about my challenge,
and thanks in advance to help me out!

I also was considering to go LOW TECH!
by putting ocr/ text recognition software over the data fields. ( price and date-time) and manually progress as each new data is updated in records.
I am sure there must be any another better and more sophisticated method to
do what i am trying to do!
Please do enlighten me!
regards
Omkar
