Quote from Aok:
Triple A.
What do you need from your charting?
Ensign. Probably the best charts of the 3.
But no floating charts. Limited to 1 monitor or stretching your desktop across all your monitors. Best/most helpful website. Extensive video tutorials. Most expensive. I used Ensign for HSI, Dax with IB. No problems. Excellent with symbology help.
Sierra. Solid and inexpensive. Interface for me is a little awkward. Lots of options for timeframe/chart display.
QT. Best customer service. Good charting, unbeatable price. Biggest con is ZERO formula capability. You can write paintbars, but you cannot write your own indicators. Works with TI seamlessly if you need limited scanning real time.
As far as the thread is concerned IB data is not better than Esignal. Esignal data actually is OK. Not overseas though. It's just that it can lag and has reliability issues at times. Those times are usually when you need it most. Fed days etc. However IB and Ensign work fine.
