Quote from Thunderdog:
I used QCharts for a few years and switched to eSignal several months ago. QCharts is easier to use and, as I have said in posts to other threads in the past, the software is downright inspired. However, the data feed is slow, unreliable and almost never real-time. As my trading time frame decreased, I found QCharts less and less suitable to my needs. When I switched to eSignal, I noticed 2 striking differences. First, eSignal is less easy to use. Second, eSignal's data feed is excellent. As lazy as I may be, I'll take reliability over ease of use any day. But give me both, and you'll really have my attention.
