ctrader brokerage firm

Never going to happen. How many brokers do you think will use cTrader if cTrader becomes a broker? Also, being good at writing trading software does not a broker make.

There are hundreds of brokers throughout the world. You cannot impose your ideology on the entire planet. If you do not like, use an American broker.
ECN or not, what I care about in the end, is connection (lag) performance, slippage, fulfillment speed, spreads (including amount for commissions), and how they are regulated (ie: client accounts segregated from their own, as in DE, GB, N.A., AU regulations for example, not Cyprus or Mauritius or places like that).
No one broker gives you 100% of everything being perfect. But I have tried ICM and they come pretty close (only criticism is fulfillment time that could be faster, but their MT4 server, for example, are 3 to 4 times faster than other brokers - cTrader, however, seems to be identical across all broker platforms from where I sit).

i think fxpro is a good broker and also regulated by fca. hope it helps.

I found Pepperstone to be Great and for the minimum price of entry offers some of the best spreads Eur 0.0 - 0.2 and fast excecution what more are you after, spend your money elsewhere.!
