The Chase for Liquidity in the Decentralized Forex Market
Liquidity is especially important in all financial markets. The Foreign Exchange market is an OTC (Over-The-Counter) financial market that operates as a vast decentralized network. In this market, many different providers offer the same exchange rate, and there is no single quote at any given time. As a result, quotes for the same currency pair can vary, making the pursuit of high liquidity even more essential.
Liquidity Aggregation
Liquidity aggregation involves gathering orders from multiple sources and routing them to a large executing entity.
A retail aggregator combines small retail trades into larger orders that can be filled by a major market participant. These larger participants have direct access to the extensive liquidity of the ECN network. Retail aggregation benefits every market participant by:
-
Providing access to the best possible spreads at any time
-
Enabling trading with minimal slippage on order execution, especially during news releases
-
Facilitating the easy execution of large order sizes
-
Continuously diversifying order execution risks by using several liquidity sources
Forex brokers can act as retail aggregators, filling their clients’ orders at the best bid-ask prices at the top of the book. Brokers use electronic aggregation services to access sufficient liquidity. The software that combines liquidity from different providers into a single venue is called a Foreign Exchange Aggregator, or FX Aggregator.
Market Depth
Market liquidity is closely linked to market depth. Market depth measures how much liquidity is available at different price levels and shows the total volume at each level.
Generally, market depth is based on:
- The number of buyers and sellers
- The size of buyers and sellers
- The existence of market makers
- The participation of institutional traders
The Foreign Exchange Liquidity Providers (LPs)
A Forex liquidity provider (LP) is a participant that buys and sells currencies on behalf of others. Liquidity providers help Forex brokers fill their clients’ orders, while also trading their own accounts. These providers are typically large entities such as investment banks, major brokers, and investment firms.
Tier-1 and Tier-2 Liquidity Providers and ECN/STP Forex Brokers
There are two main types of liquidity providers in the Foreign Exchange market:
(1) Tier-1 Liquidity Providers
Tier-1 liquidity providers include very large banks and organized exchanges such as:
-
UBS, Barclays, and Deutsche Bank
-
CME Group, CBOE, and ICE exchanges
Additionally, some large brokers and investment firms that can trade directly on the ECN network are also considered Tier-1 providers:
-
Forex brokers that trade directly with Tier-1 liquidity are called ECN
-
Forex brokers that connect directly to a large Tier-1 liquidity provider are called DMA
-
Only about 10% of all financial brokers have direct access to Tier-1 liquidity
(2) Tier-2 Liquidity Providers
Tier-2 liquidity providers act as intermediaries between Tier-1 entities and brokers. Examples of Tier-2 providers in the Forex market include:
-
LMAX, FXCM Pro, Swissquote, and Currenex
Forex brokers accessing Tier-2 liquidity are called STP brokers.
