Quote move during weekend !!!!

I don't know why.Anybody can explain?
Look here

Because there is movement during the week end as well.

Looks like a local glitch to me (or an individual pricing messup ).
The prices quoted on your screenshots after the "move" are what I have quoted on mine since the close of the market. I just looks like your quotes dropped back to the same as everyone else all of a sudden.

Oanda is interesting cause they update their quotes thru the weekend. You can even trade them if you want to pay the spread.
As JW stated prices move on the weekend - where do u think that Sunday open gap comes from?
You can just select the 'Ignore weekend data' option if you want.

Oanda typically starts wiggling around 1:30 or 2:00 EST on Sundays, unless somebody blows up France or Godzilla is sighted moving towards Yokohama, in which case there can be movements earlier than that, even on Saturday.
