Feedback FIX API

Hello all,

The FIX is available since some months now.. someone can tell me the feedback in demo / in live on FIX API of ctrader ?

- The latency between quotes ?

- The latency for a market order (major pair / right liquidity) ? 

- There are many difference between ctrader FIX Api and Hotspot or Currenex FIX API ?

I don't understand very well the architecture of ctrader / Fix engine. 

Often brokers by example fxpro / icmarket have their own fix engine located in have their own datacenter or here it's in the same datacenter that ctrader ?

I see many message on London place... there aren't any ctrader/fix engine in NY ? only on london ?

Thanks for your feedback.

​Regards.
