Chronicle FIX
Chronicle FIX is a low-latency FIX engine built on Chronicle Software's high-performance Java libraries. It parses and generates every version of the FIX protocol with deterministic latency, eliminating the garbage collection pauses and jitter that disrupt trading systems under load. Firms deploy it on-premises or in the cloud as a lightweight set of class libraries, with built-in failover and per-session customisation.

FAQs
Find answers to common questions about our products, performance and implementation.
What Is the FIX Protocol?
FIX (Financial Information eXchange) is the standard messaging protocol for electronic trading. Banks, brokers, exchanges, and funds use it to exchange orders, executions, and market data across versions (such as 4.2, 4.4, and 5.0).
Why Does Latency Matter in Trading?
Prices in electronic markets move in fractions of a second. Lower latency gets orders to market faster and closer to the expected price, reducing slippage.
How Do Microseconds Affect Trade Execution?
At high frequency, microseconds decide whether an order reaches the book before the price moves or a competitor fills first. Chronicle FIX holds New Order Single round-trip latency under 4 microseconds.
Does Chronicle FIX Support Regulatory Compliance Requirements, Such as MiFID II?
Chronicle FIX logs every FIX message with optional persistence and latency checkpoints, and supports deterministic replay for audit. Additionally, it provides the record-keeping foundation that regulations require (such as MiFID II). Transaction reporting remains the firm's responsibility.
