SPX Expiration

Take it in stride.

 

same deal on the ndx ...

high was 1499.13 -- settlement price 1455.83

 

I saw a post somewhere on ET a while ago where someone researched the Thursday closing price on SPX and the opening Friday SET value. I believe the largest gap was like 20 or 30 points so becareful about holding SPX until Friday morning.

 

Who is doing this ? How do they do it ? Is it legal ?

 

set is usually about 1 atr away max.
