Trading the +++++++++++++++++++++++++++++++++













Trading the S&P 500 e-mini futures. I believe there's a mathematical
formula that floor traders use to set an upper resistance level and a
lower support level for trading this futures market based on the
open,high,low and close of the preceding day. What is this formula?

This is sometimes done using moving averages, often 9-day or 14-day.

It is also done using a weighted moving avarege of volatility.

EXAMPLE:   S&P 500 has average intraday volatility of +/- 1.5% over
the last 9 days.  So, "resistance" occurs when the market rallies
1.51%.

Good luck!

P.S.  If these technical systems actually worked, I would be on the
beach in Maui...   :-)

Goerge Angell has a formula for this.

I have know idea how accurate it is.

Good luck.
