Best ECN Brokers for automated trading using C language or MT4???

Dear friend,
I want to write code to do automated trading, but I don't like to learn JAVA or any new languages. I am familiar with C, and MT4 (looks very similar to C). Can you recommend such brokers (must be ECN) that best fit me, better in USA?

(Note: My trading will be almost purely "data" driven, so just need input tick or minute data etc., and using some of my own algorithm ideas to do automated trading. I want to write everything on my own language and don't use indicators. So I only care about the "data interface", not really care about the graphic interface)

Any information would be very much appreciated!

for MT4 ECN try: ATC Brokers or MB Trading (ATC is cheaper but higher deposit to open account)

Thanks for the Info.....I did have impression of MB trading before put this, just wanted to narrow down to the best and the safest one.

Is ATC a "regulated broker"? Anybody knows things about "fastbrokers"?

It looks like Dukascopy has very good reputation, but it's not in USA and it seems just started with allowing MT4.

For "Aja": are you sure ATC is cheaper? I checked both webs: MBT says "$2.95 per 100K USD", ATC says "$0.40 per 10,000 lot size".
Thanks.

MB has both sided negative swap PLUS the currency price factors into your margin. ATC is always 100:1 and you wont be losing on swap with every trade. (hopefully it cancels out) - I cant strongly argue against using either - both are good shops. I just prefer ATC (NFA regulated) because I can hedge and FIFO as I wish. - I'm waiting for Duka to get their MT4 together. I'll give it a look in the fall to see if its fully debugged. - Skip Fastbrokers they're just a 'white label' for FXDD.

Well the FX Open MT4 ECN is a decent option. Plus it offers high leverage (for those who would like that).
