has anyone tried Global Zen Platform? What was/is your experience with it? I moved from NT to Sierra Charts and was curious about GZT. Thx

There are a couple of other threads about Global Futures as a broker on NexusFi (formerly BMT).

In terms of the Zen Trader platform, I am not sure if you are aware that this is just a white label version of OEC Trader owned by Gain Capital - and there are several threads on NexusFi (formerly BMT) that discuss OEC Trader that may help with your deliberations.
