I'd just like to say I demo'ed this software and it's really not ready for "prime time". Before the latest release this weekend, I couldn't even get the software to run (yes I installed the runtime package).
After finally being able to run the software, it took a few minutes for me to setup my connection to IB & Zenfire. It wasn't 100% intuitive but the video tutorial on the ATrader website did help.
I didn't quite understand the purpose of having IB for historical and Zenfire for real time charting (as you can pull historical ZF quotes, just not the full Bid/Ask quotes). Since IB doesn't run on the weekends and forces a shutdown each night, this is a real big hassle. Maybe I just misunderstood how this part works.
I'm not much into indicators but there are a decent selection for those into it. I was searching for a good tool to display volume distribution profiles and ATrader does a good job. No real complaints but I wasn't really "wow'ed" either. Scrolling the charts is done via the keyboard, which I presume one could get used to but the lack of scroll bars and to be able to click & drag to move around & zoom was a little disappointing.
It appears there is an annoying "register now!" reminder that pops up pretty frequently, which obviously won't be a problem if you register.
For me, the software just isn't enough for me to shell out the money. It definitely has a "low budget" feel and unless it addresses some key data connection (mainly directly feeding of ZF for live & historical charting) and user interoperability (installation, hotkeys, charting) issues, this tool has very limited advantages to any of the established platforms out there.
Just to add, what I did like was the volume profile capability, multiple supported data feeds, the integrated ability to upload charts, and of course the low cost.
