I'm a pretty active trader.... and really all I need are the 60 minute charts, It really doesn't matter if they are delayed 15 or 20 minutes.
I have all the real time charts, a trader could want, along with depth, but as long as your playing the 3x ETF's it doesn't matter.
Yes for individual stocks, you might need all the toys, but you don't need anything more then a 20 min delay on your favourite 3x etf.
IMHO of course,
Your needs may differ.
