hi Support,

Sorry if it is a newbie question.

I am trading in DEMO environment and about 0.5 hour ago I got this strange trade - can you please explain how can I get a price which is not on the Bid or the Ask Stream?

Also - can you please advise on how to protect from such incidents in code?

Here is a screen shot of the trade (EUR-USD, tick graph):

As you see the market order gets filled and closed for the last available tick price, not according to the line that connects the prices:

In your particular case, it looks that for some reason (market volume, server or feed lag or other) the order was not closed by the latest Ask price, but for the price of third to last tick.

hi Support,

Another possible explanation - please correct me if I'm wrong :

Could it be that at the time the stop loss was triggered (a market order execution) - there was no volume at the referenced ASK price hence the order was filled from a deeper level in the order book? --> Slippage?

That was what we referred to as "market volume" and you elaborated on this. Since precise system (some technical issues), market (volume) and order data at the particular moment are unknown, we can only speculate about the cause. For general case see order execution principles at Platform Manual/Execution process section in JForex wiki https://www.dukascopy.com/wiki/.
