Forex glossary
Liquidity providers
Liquidity providers are banks and non-bank firms offering FX quotes and trading capacity. Available prices and sizes depend on the instrument, credit and execution rules. More providers may broaden access, but do not guarantee a tight spread or execution of an entire order at one price.
Illustrative example
How does it work in practice?
Suppose provider A quotes to buy 100,000 EUR and B another 50,000 EUR at a different price. A 200,000 EUR sell order exceeds both amounts; having two providers does not ensure a complete fill.
A case to work through
Connections and available amounts
In a fictional file, providers offer 40,000 and 60,000 EUR for a 150,000 EUR order.
- Even with independent available quotes, total size is 100,000 EUR.
- A further 50,000 EUR is needed.
What follows? Check additional depth and acceptance conditions.
Example boundary: Quotes can change and may not be independent.
A useful distinction
Liquidity providers / Tier-1 dealers (market makers)
Tier-1 is an informal institution label; liquidity provider describes a function.
