What is liquidity aggregation for a forex broker; key hub functions

How liquidity aggregation works

The market liquidity concept entails the presence of a buyer and seller for an asset at current prices without any delay. Liquidity aggregation is conducted through the operation of the software that transfers quotes and market order flows between liquidity providers and the trading platform.

Customer loyalty largely depends on the quality of liquidity provided, so it’s crucial to choose the optimal software package.

Main functions of hubs

A liquidity aggregation center (or a hub) is a program responsible for the basic liquidity provision functions, along with risk management, broker automation, and company scalability.

  • The next important feature is setting up groups of traders with automatic redirection between A/B-books depending on trading style or changes in market volatility.
