thanks a million for explanation! we might as well to open a demo account with the other broker but it is hard to know what level of 200 ema of what broker price will respect, one time time it respect one level the other time - another. See, FXCM have it on the same level with Forex.com etc., on the other side are Alpari uk and other respected brokers, they are kind of divided in two groupes. maybe for sure take a middle level then we surely wount be far away from the truth.
The reason for the deviation of more than 80 pips that we see in the forum is something else: Some brokers include the "Sunday candles" (quotes that happened before the start of the financial week on Sunday, 1700 PM US Eastern Time), some brokers don't.
Brokers that include the sunday candles display 6 candles per week, the others only 5. And this leads to dramatically different EMAs.
The first chart below show 5 candles per week, the second chart 6 (vertical lines behind the "Sunday candles"). Note the differences of the EMA200.

Looking back, prices sometimes seems to respect the EMA200 better on the upper chart, sometimes on the lower. Difficult to decide for THE truth. Perhaps there is no single daily EMA200 that the majority of the big boys are using.
P.S.
But the EMA10 rocks on both charts.
