at 12:15 i can see that S&P has fallen by 160 ticks from yesterday's high, and euro stoxx had not fallen that much..i was very sure that S&P and euro stoxx both will fall because there is an unfilled gap at 1065 which is still 40 ticks below the current price, and it behaved as expected...the spread was at 1505 before 12:30 i.e. euro stoxx opening, and spread opened at 1531 and rose upto 1544 within a minute, and both S&P and euro stoxx fell like hell
