cServer is a high-performance back-end system that undergoes constant optimisation to ensure the best support for the entire cTrader solution. Contributing features include the following:

Reliable Infrastructure

A strategic location in the Equinix LD5 and NY2 data centres alongside major liquidity providers, ECNs and aggregators with fibre cross-connects.

Integration and Reporting

Integrate with cTrader using an à la carte menu of APIs with different business responsibilities. Foremost examples include the Manager’s API, which allows the creation of custom tools for working with cServer entities, and the WebServices API, which enables the integration of cTrader with brokers’ client areas.

Integration with 50+ Liquidity Providers

cServer is already integrated with major liquidity providers, making client onboarding easier and faster.


Network interfaces are connected to a redundant 10GE network fabric to ensure ultra-low latency and high throughput. Routing occurs via a global proxy cloud to evaluate and correct last mile latency for traders.

cServer uses flagship hardware supplied. Our resources also include hundreds terabytes of NVMe storage, tens terabytes RAM, and 10+ THz CPM. cServer communicates between multiple data centers using secure dedicated channels. Additional backups are stored in supplementary data centers in other countries.

cServer Model

This diagram shows the full scope of the cTrader architecture model.

Order Processing

Created to provide the most advanced trading experience for hundreds of thousands of traders simultaneously, cServer boasts an impressive capacity for order processing and management.

Straight-through Processing

Designed from the ground up for STP execution, cServer’s order routing engine has been optimised for fast and stable communication with multiple counterparties to ensure the lowest rejection rates possible.


To reduce operating costs associated with order execution, you can maintain an internal order book either exclusively or in combination with STP. This forms a hybrid model and vastly improves risk management.


cServer leads the way in reliability and security standards for retail-focused platforms. With high-availability servers and robust underlying technologies, you can have peace of mind by delegating platform security responsibilities to Spotware.

Environment Segregation

Each solution is hosted in an independent environment to protect against any possible disruption from other brokers. This is made possible through the industry’s leading VMware vSphere and Zenoss, which segregate and monitor each environment.

Sensitive Data Protection

Your customers’ personal data are not required to operate trading accounts. Only margin-related information is necessary. Anything that is disclosed is subject to strict data protection practices.

Robust Services

cServer offers unsurpassed operational reliability, including failover infrastructure, redundant network connectivity, established disaster-recovery methods and reverse-engineering-resistant server components.

Proxy Cloud Protection

All traffic coming to and from cServer is routed through a proxy cloud to protect against unauthorised, malicious connections and DoS and DDoS attacks. Additionally, SSL encryption is in place.

Access to the majority of integration APIs is regulated via IP whitelisting as well as clearly defined access rights determined on a per-connection basis.
