Stellar Trading Systems


A complete trading system solution, Stellar provides an intuitive front end with comprehensive order and risk management.

The Stellar front end has an emphasis on speed, displaying market data and routing orders as fast as possible. The Stellar architecture places the complexities and workload of the trading system onto the servers, freeing the front end to focus solely on trader interaction. Stellar responds instantly, even in the busiest of market conditions.

Uniquely, every aspect of the front end, from price ladders and view to order book and spread matrix, is fully customizable allowing traders to tailor their screen layout identical to that of their existing system. This minimizes the disruption and time out of the market that is traditionally associated with switching to a new trading system, whilst the trader benefits from enhanced performance.

  • All standard trading screens, including grid view, price ladder, price ticker, and time and sales
  • Powerful synthetic order types, including stops, icebergs, brackets, OCOs, and conditional orders

Stellar spreadMachine

The Stellar spreadMachine is a server-based cross-market cross-product spreading tool.

The spreadMachine automatically works inter-market spreads on the trader’s behalf, managing leg orders and balancing the spread as required. Complex trading strategies can be implemented, with the spreadMachine capable of executing spreads with multiple legs, any number of which may be working in the market. All of Stellar’s powerful synthetic order types are also compatible with the spreadMachine such as icebergs and bracket order types on spreads, providing unparalleled flexibility and execution.

In today’s markets automated systems frequently compete with one another. To be effective, automated spread execution demands exceptional performance. The Stellar spreadMachine operates at the core of the trading system – it is a server based system designed for deployment within exchange colocation facilities. This allows it to build upon the high-performance order routing engine within the Stellar architecture and respond to market movement as fast as possible. The spreadMachine harnesses the power of its server hardware whilst leaving the trader’s workstation free to focus on order entry and price display.
