Hi, Since most now roll over to the June ES contract to trade, I noticed that difference between the March ES contract, (which now should trade close to the SPX), is trading pretty close the June ES contract as well. From the Esignal data that I have, I have the June ES contract closing at 1315.25 and the SPX closing at 1315.48. (The March ES closed at 1313.25). I might have to check it live. I also know that the futures close 15 mins after the SPX does. Is this because the interest rates have come down, as a result the basis between cash and futures have decreased?? Just wondering. Thanks. Daytrader85
