A complete explanation of how liquidity works for white-label brokers — LP types, FIX connectivity, pricing models, multi-LP aggregation and how to choose the right liquidity partner for your business.
When your client clicks "Buy EUR/USD", your platform needs a counterparty willing to sell at a price. That counterparty — and the continuous stream of bid and ask prices they provide — is your liquidity.
Liquidity quality directly determines three things your clients notice most:
Choosing the right LP is not just a technical decision — it is the single most important factor in your brokerage's competitiveness and profitability.
The top of the liquidity stack. These are major banks like Deutsche Bank, UBS, Citi and others who aggregate FX liquidity from their own institutional flow. They offer the tightest raw spreads and deepest liquidity but require:
Not accessible to new or small brokers.
PoPs sit between retail brokers and tier-1 prime brokers. They hold prime brokerage accounts with multiple tier-1 banks and re-distribute that liquidity to smaller brokers at accessible minimums. This is where most white-label brokers connect.
Specialised LPs for cryptocurrency CFDs or spot crypto. They aggregate from major exchanges (Binance, Coinbase, Kraken, OKX) and provide a single FIX stream covering 200+ crypto assets. Critical if you offer crypto trading instruments.
Aggregation layers that pull quotes from multiple LPs simultaneously and route each order to the best available price. Best-in-class execution quality but adds infrastructure complexity and cost. Recommended for brokers trading $500M+/month or handling sophisticated clientele.
All professional LP connections use the FIX (Financial Information eXchange) protocol. Here is the end-to-end data flow:
| Factor | Tier-1 Prime Broker | Prime-of-Prime | Crypto LP | Aggregator |
|---|---|---|---|---|
| Minimum deposit | $1M–$10M+ | $50K–$200K | $10K–$50K | $100K–$500K |
| Spread quality | Tightest | Excellent | Good | Best (multi-source) |
| Accessible to new brokers | No | Yes | Yes | Advanced brokers |
| Typical spread (EUR/USD) | 0.0–0.2 pips raw | 0.1–0.5 pips raw | N/A (crypto) | 0.0–0.3 pips |
| Protocol | FIX API | FIX API | REST + FIX | FIX (internal aggregation) |
| Best for | Large institutions | New/mid-size brokers | Crypto-enabled brokers | Scaling brokers |
A liquidity provider (LP) in forex is a financial institution — typically a large bank, prime broker or specialist aggregator — that provides tradeable bid/ask prices to your brokerage. When your clients trade, your platform either passes the order to the LP (A-book) or internalises it (B-book) and periodically hedges net exposure.
No. New white-label brokers almost always start with a prime-of-prime (PoP) LP rather than a direct prime broker. Prime brokers require very large minimum deposits ($1M–$10M+) and institutional track records. PoPs aggregate from multiple primes and offer access at much lower thresholds ($50,000–$200,000).
FIX (Financial Information eXchange) is the industry standard protocol for electronic trading. Your trading platform communicates with your LP via a FIX session — a persistent, binary connection that streams prices and executes orders at sub-millisecond speed. Yes, you need it — all professional LPs use FIX.
LPs typically charge a combination of: minimum monthly volume commitment (e.g. $50M/mo or pay a shortfall fee), a per-million-traded commission ($20–$60/million USD), and potentially a monthly connectivity or software fee ($500–$2,000/mo). Some LPs offer all-in pricing via a slightly wider spread instead of per-trade commissions.
Yes, and for a growing broker, multi-LP aggregation is recommended. An aggregation layer compares incoming quotes from multiple LPs and routes each order to the best price. This tightens spreads, reduces slippage and prevents dependency on a single LP. CTATech supports multi-LP aggregation configuration.
