Financial history doesn't repeat itself, but it often rhymes. You can't be stupid enough to trade off anything I say.... I'm lucky they let me out of the straight-jacket long enough to trade.

Rate of change on the SPY



Here is your Scatter Graph
See it?
lets add some lines for the Impaired.
I even added a 3 and 5 dma.
Admittedly the Friday move has the rate of change in a steady .4 ish move up over the past 5 day period.
But here is the money.
This is a Statistical Forecast/Model of the SPY.
It's impossible to forecast the massive swings, but if you look at the 5dma vs the 5dma of the actul it's close... of course Like I said Friday was very outside the model but it's close I'd expect the market to Mean Revert and look more like the model over the next 3 days.
The model if you notice "Forecasts" out 6 days ahead. If you notice the Actual market data stops on friday and the forecast moves out 6 days....
Don't ask me why I for casted it out 6 days.
And ... Since you aren't a moron, you know that the further out in time you forecast, the more errors you get.
If you want the numbers
The forecast for monday is a +.03 and the 5dma of the forcast is +.04
Now the actual 5dma of the Rate of change is +.48

Hmmm well I bet we could also run the Marin of error.
But excuse me if I use the 5dma for that.
