I have used both Nextrend and Tradestation Pro.
For me Nextrend is the best there is as far as quality of feed, ease of use and the prompt responses from the support staff.
I have also found that Tradestation Pro demands too much of computer resources unlike Nextrend.
I also tried esignal and Qcharts but I will stay with Nextrend for the reliability and unbeatable customer support.
When was the last time that you were able to speak with a real support person within 30 secs, happens 90% of the time at Nextrend.
That is important to me,
