I still say though that the best 2 instuments on a margin basis for how they move are the HSI (~$9500 US) and HHI (~$5500 US). They are outstanding intraday trenders, best in the world (highly correlated, of course, easier to start out with the HHI).
yes. good for day trading esp HSI. occassionally its movement could be very messy, spiky. mostly I have to use market order to enter the order. its movement is far to rapid for me to use limit or stop order for order entry
don't know what those guys in CME doing. Look at NQ. it is ranging from 7400 to ~7700. yesterday day range about 100 points. it is not that great compare with Feb / mar 18 where day range could be 400 points !
