The biggest reason I like using Qcharts has to do with the time saving functionality the software provides. By importing an initial download of stock symbols (from stocktables.com or any other source), one can quickly and easily cull the initial sort for the fundamental parameters. In fact, in under thirty minutes you can cull the entire stock market for symbols using a Quotesheet from Qcharts. In addition, using the QClient Continuum to import data directly to an automated program (Wealth-Lab Developer, Amibroker or other 'Do-It-Yourself" Program) additional time is saved. Also, changing fractals requires nothing more than a single click, so the same channels drawn on a daily fractal remain in place on lower fractals.
I occasionally experience data lag with QCharts, but most of the time, I can rectify the issue by switching servers. Rarely does the lag become severe, but it has happened. As johnyy40 pointed out, ESignal has purchased QCharts. However, everyone currently finds themselves in a 'wait and see' mode with respect to how this merger will shake out.
