Haven`t find any kind of such problem at the forum.
I`m always ready to move my funds out from the Dukas, because it is already at least 5th time I encourage non-market execution during about one month of trading here. I wrote to support at the first time I encourage the problem and received the answer like everything is going like it should be. They don`t think that it is a problem.
Now, after about one month of trading, I decided to write about it on the forum to verify if this problem occurs to all or only to me.
I haven't find any negative feedbacks about Dukas over the internet so I believed that such kind of problems are likely to be met at low level brokers but not Dukas.
I was sure that it is a bug or technical problem, but support answer another way.
I had a 0.1mil short order on EUR/USD. Today I decided to close this order during American session manually. The market was flat.
Here is the Screen of what I received (M1 timeframe):

As we can see, such a small order (only 0.1mil) was closed by two parts. One at about 1.3352 as it should be, and another part at about 1.33625!!!
Here is the tick screen:

And this is not all)))
Here is the activity log screen:

As we can see, the order was filled at 1.33525 price.
The same confirmation we can get from the trade log:

It is like all the order was filled at 1.33525 price.
But actually I was billed at 1.335583 as we can see from position report:

It is the first time I have such a problem with manual closing of the position ever.
But I have regular problem with stop loss execution.
Fist, SL is sliding constantly up to 20 pips.
Second, I had several times non-market execution of Stop Loss like this:

This SL was moved to Break Even at 1.32235 but Dukas closed it
-21.5pipsEverybody has such a problems here?
Is it usual for Dukas?
