Howdy, I'm guessing that the best TICK indicator is one that you create from scratch, but right now I'm trying to compare TD Ameritrade feed through Quotetracker versus IQ feed through QT. I always "felt" TD tick was off but right now I can't even compare. It's not a matter of lagging...they're not even close! Would one or two of you mind volunteering a screen shot of your $TICK chart for today, Friday, so I could at least compare some high/low readings? Thanks much, V.
