How to get Intraday Technical Data from Yahoo

Hi

I am able to get the current values for Nifty through yahoo finance using the following link.
http://finance.yahoo.com/d/quotes.csv?s=^NSEI&f=snd1l1c6gh

But I am unable to get the intraday values for RSI and slow Stochastics through Yahoo Finance.

Can anyone help me out. I am trying to write a small program which performs trend analysis on intraday data.

Everything you get from any data provider is just price (O,H,L,C) and volume. Software uses it to calculate RSI, etc. Nobody gets RSI value from Yahoo or anyone else. You need to study how studies are made so you can understand...else you are in for a long day. EVERYTHING calculates off open, high, low, close and volume. That is all anyone EVER gets...UNDERSTAND?
