Strongly concur with recommendations for e-signal. I daytrade index futures and inaccurate data, any lag, and less than near-perfect reliablilty are simply unacceptable. E-Signal meets those criteria with flying colors ----- have used them for nearly a year now with no problems at all.
I've used eSignal, Quote.com (Qcharts/Qfeed), AT Financial and CyberCorp. eSignal is by far the most reliable. I have had real-time data since 1996 and eSignal continues to be the only reliable choice I've found.
Great screen layout, Ken DTU - but don't you also display your analysis software (which do you use) ?
