Cramer always talks about "ordering" an "S&P oscillator" form their web site. How do you get that??
The S&P Oscillator is a short term measure of current market sentiment. S&P has their own proprietary formula for computing this. When the value of the oscillator exceeds 4, it generally means the market is overbought, and when it is less than negative 4, it generally means the market is oversold.
The S&P oscillator is not publically available; you must subscribe to their Trendline service which runs about $1,000/year.
For all of you out there searching for the S&P Oscillator that Cramer talks about on Mad Money, stop looking, you won't find it.
