that's just one chart.
and if i get the 5K monitor, i'll have charts like that for:
SPY, VXX, AAPL, MSFT, GE, JNJ, XOM, FB, NFLX, AMZN, GOOG.
plus T/S & L2 on VXX in addition to SPY.
and prolly still some space for other trinkets like news feeds.
i honestly can't imagine trading full-time by phone.
then again, you trade on week/month cycles
while i trade on minute/hour cycles. ;-)
