Quote from Don Bright:
OK, take the spot price, add current day fair value (www.stocktrading.com/Tradinginfo.htm will help), and you get a number. Now check where the futures are trading (eMini's are trading), and determine the difference between your adjusted FV number and the actual futures number. Divide that by the spot price to ge an up or down opening percentage. Apply that number to previous day's close. Then, depending on how far the market is opening up or down, determine your envelope (between .2 and .8 generally). The envelope is the variable.
Using today (Tuesday) as an example (approx).
Previous SPX (spot close) = 1445.90
Today's FV = 10.72
Total (est. Parity) 1456.62
Emini's trading approx 1467.75
Opening up from FV 11.13
11.13 divided by 1445.90 = .007
.007 times (stock) AFL close 59.52 = .41 making predicted opening price of 59.93.
I put a . 4 sell envelope which gave me a 60.14 sell order. Stock opened at 60.23, I bought it back between 60.13-60.18 to make $160.00 this morning on Aflac.
(Don't get too bogged down in the number, focus on the concept of fading gaps).
This morning I ended up $320.
This morning, no buy orders.
Good luck!

Don has it on his site;Quote from econometrics:
Don, could you elaborate on the FV? where do you get that 10.72 FV ?
Quote from econometrics:
ok so thatz the F = S e^(r-q)t term in forward pricing.
but where do you get the q (dividend estimate) from?
how do you account for the vol of r?
