I have a nice little system that so far works nicely for intraday trading the qqq's with 5 Min charts. I have also tried the nq's and will probably gravitate towards them, however, they are a bit "spiky" for my taste. My system catches a trend that lasts more than 5-10 minutes beautifully, i am looking for markets (whatever they may be, futures, currencies etc.) that are highly liquid and have the potential for longer intraday trends (longer than the nq's)... Thanks for any help.
