Help with NY Close Broker

Hi!

I could use some help to wrap my mind around this New York close chart thing, which is particular present if one reads through price action threads on this board.

I use metatrader 5.

A) How can I determine which server time a broker is using. Only some are so kind and write it on their website.
B) Do you know a MT5 NY close broker which you would also use to deposit money and really trade?

RoboForex was mentioned. The bars of RoboForex creatly differ from my ActivTrades bars. But some say that RoboForex is not really NY close due to daylight saving time issues.
Also what seems to be strange is that when I go to 1 minute chart the bar is 1 hour in the future to my local time. I live in Germany so my local time is middle european time. German time + 1 hour is not exactly New York time… This is why I don’t understand why people say RoboForex is NYC.

Help would be creatly appreciated!

And can someone please post a screenshot of a EURUSD H4 chart in New York close in good quality?
Thank you very much!
