close rate difference

hi all,
im relative new to trading forex, i have started with a micro account at fxcm,.
a week ago i recognized that at my usd/jpy trades the announced close rate is different from my chart, the funny thing is this only happened in usd/jpy and eur/usd so far, have some gbp/usd trades open but there the rate is identical.
i have wrote to fxcm 3 days ago to ask what this is but i got no answer, the difference is atm about 2-3 pips.
may u guys can explain me what this is and if its normal, i think if it is the spread it must be in all trades - im confused.
thx in advance

I'm not familiar with FXCM's platform but it's actually 0.2 pips in your favor.

To close your Usd/Jpy short you need to Buy and the quote in the 'Advanced Dealing Rates' is 91.717/91.731, according to
the 'Close' on the positions tab you would get 91.729 (if that's an executable price).

Maybe there's a lag in quotes updating between the positions tab and the chart/dealing rates?

Which price do you get filled at?
