if you are looking intra-day breakout/breakdown setups, you will need 3-4 wide screens
#1 at lower left: SP500 E-mini future and Nasdaq 100, 5 min and 1 min charts and level 2 plus tape.
#2 at lower right: 3 to 4 stock's level2 and tape, with blogger on top
#3 and #4 on top, 6 to 8 stock's 5 min chart on each screen in order for you to discover the breakout setup. ( You will be watching 16 stocks, So you will less likely to miss a good setup)
and better with an assistant watching another 2 for you.
