Dukascopy: what do the fills on large orders look like?

Hello guys,
Those of you who trade with Dukas, what's your impression on their fills on 5M-15M orders? They seem to have enough liquidity to fill 1-2M in one go without any significant slippage but what happens when the size goes up? Say during London session their spread on EU is .5 for 1-2M so what do you think will be the average spread for 10-15M? You'll ask why Dukas and not Marex or any other institutional broker...well Dukas are able (at least they say so) to arrange a guarantee letter which is a huge advantage actually.
Thanks!

You can arrange a letter of credit/bank guarantee with other brokers too. LCG for example.

On Currenex and Hotspot you can set up the platform so that it displays quotes for amounts larger than what is on the best bid/offer. Not on Dukas unfortunately, although you could program something similar using their api. But keep in mind that quotes are indicative only, actual fills might still be different.

Thanks for your input shrike. But do you think they're capable of filling relatively large order without any significant slippage? We all know that their advertised 100M liquidity is not exactly on the best bid/ask and not even close to that Hence I'm asking those who traded those sizes with them.
As to the LCG there're some mixed reviews on them. How their fills look like?

Well, if you are looking for liquidity, Dukascopy is one of the best places to go. One reason for this is because they do have a connection to ICAP EBS.

Mixed reviews: Those reviews mean nothing, because you can find mixed reviews about every broker.

Bank Guarantee: I always have to laugh when people ask for a bank guarantee. Does not make sense. It's like driving 500 MPH on a dangerous street, but asking for a seatbelt. There is much more risk involved into FX trading itself, where 95% of the traders lose, than the risk of losing Money becuase of a bankruptcy.

Well trader121 I tend to disagree with you here. Surely most of the traders loose because of their own limitations. BUT let's not forget about MF and PFG. So IMO if we can mitigate somehow this sort of operational risk then our losses can be blamed solely on us Hence I do appreciate a broker who's ready to be funded with only 25% of my total equity. And the rest will be safer in my bank.

I don't trade the lot sizes you are talking about, but looking at the market depth now on my Dukascopy platform on EU there is around 175million USD of market depth within 2pips bid or ask. Even something like NZD/CHF has around 25million USD withing 3-4 pips both sides.


Hope this helps.
