It's just funny to me that if you bought the SPX every day on
the close and sold on the open the next day that you would have
made 380%. But if you reversed it and bought on the open and
sold on the close you would have lost about 40%. Amazing the
contrast.
Obviously those stats stop at April of last year, I'll write a
TS strategy so that we can see the current stats, however that's 17
years already (from 1993 - 2010), so I'm sure the numbers are about
the same
yeah commissions would be high. But that's not the point,
that's not a mechnical system because of the number of trades, the
point was to show you that the market has made the majority of its
gains over the years on over night gaps
It also shows you that it's best to sell longs on gap ups in the
the morning vs at the close
It's just funny to me
The majority of market gains come overnight

Title: EMA filter of overnight

It would be interesting to see if these overnight gaps move mostly in the direction of the 13 or 34 period EMA.
