When the nq spiked the other day it didnt even take out my .23 stop on the QQQ. Easyrider, just as a side note, that NQ spike was a very rare event. I can't ever remember an NQ move of 60 points in 30 seconds that was not a major event that affected all other indices, stocks, bonds, and the broad market in general. Good luck on your QQQ trading. Something you might consider doing- determine your buys & sells based on the NQ chart, but place orders on QQQ (you will have to use mental stops for this). This won't be an exact correlation, but it allows you to "practice" on the NQ's while risking real money and getting a "real" trading feel.
