My order close itself.(onada from myfxbookcontest)

Yesterday,i hav open buy order EUR/USD from 1.2485 and 1.2457 about 10,000,000 and 1,500,000 consequently.
But this morning , i found it has been closed since 1.24453 for both order which i have not set TP/SL.
At that time i have net asset 317,xxx and sit in the first position for oanda contest.

I need to know what's going on wih my position.
My order was still opened the lowest of that day(1.2408) but has close itself at 1.24453.

What ' s oanda do with my order,Can i trust this broker?
I need to share this to everyone that find the problem like me.

I trade real money with Oanda, and feel that they are pretty honest for everything (I really didn't have this feeling with some other brokers I went before). I would rate them as one of the very best MARKET MAKER around.

But I really don't know what happened to your orders ... And seems that it was on demo, right ? (you talk about the contest). I doubt any broker would trick you on demo :) Why would they ?
