Deutsche Bank, #1 global FX liquidity provider for the last five years, has stopped providing FX pricing to most or possibly all of its liquidity aggregator customers. These include ECNs, DMA providers, Tier 1 and 2 Prime Brokers. Typically these firms cater to mid-size retail brokers, hedge funds, Commodity Trading Advisors larger, and more active retail forex traders.
It is unclear whether they have also stopped pricing retail aggregators such as FXCM, Alpari, and Oanda. However this is highly unlikely given the profitability of retail trading flow, and the fact that the largest retail brokers are Top 10 customers of Deutsche and the other major FX banks.
