I can recommend IG too, best Price/ Value Ratio
Level 2 is their high volume trader LII/ DMA Platform - if i remember me correctly there exist several requirements (volume, deposit) to use it.
But PureDeal (DMA Level 1) is good enough for that business the majority is interested in.
Contingent Orders, 1 click trading etc. All in all a nice toy.
other DMA providers are GNI Touch, Saxobank, City Index, Global Trader ....
