@Rad, let us also forget about the developer companies involved. Lets take this a step further.
The data out of NSE, whether a spreadsheet converted to an xml doc, does it have an exclusive arrangement with Nelly Data or is the stocks data open to anyone to make their apps? Or is NSE charging for this data on and restricting it to some arrangments? Anti-competitive behaviour? I saw the site
rick.co.ke and there are graphs there too but the sources of the stock data are not verified? Is data from NSE verified ?
Too many questions are coming up now... ( BTW, I'm not interested in building a stocks ticker.. )
Well, thats my contribution for a while...time to put more efforts into other stuff. :-)
Asante.
