I traded some time with Esignal datafeed and Tradestation 2000i. Because Esignal does not support anymore TS 2000i I had to find another datafeed. I took a subscription on IQfeed but had also to install Ondemandserver from RTsoft to connect the Global server to IQfeed. But I see now that several times a day my charts freeze for a few seconds to even more than 2 minutes. Especially when volume is high I can have quotes that are off 2 points from where we are in reality. RTsoft nor IQfeed can help me. Anybody who has a solution for this problem? My computer: Acer with AMD Athlon IIx4 630 quad core processor. RAM 8Gb. I noticed that my processor is often at 100% of maximum processor frequency. Is a faster PC a solution? Maybe InteI i7 4930K processor? With Esignal I never had any lag.
