Did you drill holes in your monitors to attach those brackets? I think I may do something like this as most of my monitors are not VESA compatible. I want a two level setup. I am too spread out now.
I did not drill any holes in my monitors. Every monitor is different but for my NEC monitors I was able to disassemble the plastic base it come on and reuse the metal bracket that attached the monitor to the orginal base. It allows you to tilt monitor so I just swung it out 90 deg. so I could secure it to my wood stand. It still tilts very nicely.
Backtesting/tracking/charting is with Investor RT. Very highly recommended if you are trading equities. I trade through both IB and E-Trade. Attached is a pic of my Investor RT setup. It is infinitely flexible. This is simply my preferred approach. Note the columns in the center. They are all programmable with custom indicators and signals. Charts on the right include customized programmable buttons for timeframe, alert levels, signals, sound alerts, opening of internet sites, etc.
