here's an interesting chart I have in Multicharts.  It was giving to me by a friend from Germany who recently completed a huge database of historical market data where he took daily and hourly data going back many years into the past.  The then projects a projected price movement on the chart (which is in yellow) of what direction price should theoretically go based on the past.  The current SPX price is at the top in green.  I've been following it for about a week now for fun, WAY WAY to early for me to say much more than that, though it's been pretty accurate so far.  Last week for example it was projecting a price low on Thursday morning at 7:30 and a big rally into late Friday morning, which totally panned out.

This week it projected a high this morning at 10:30, which has panned out so far, and projects weakness into 11:30 tomorrow, and then rally from there into Wed.  Again the Yellow Line 2nd (second down from the top) is the projection line based off historical data.  The top line is the actual ES price data

if it continues to track well I'll start posting it regularly, for now just posting for fun
