Minirobots

Minirobots - Realistic Market Agents Simulation for Testing Purposes

  • simulate the behavior of trader using complex algo-trading systems
  • create realistic market conditions in your test environment to react to
  • create a realistic load in your test environment
  • test at the confluence of functional and non-functional testing to catch intermittent functional defects that only manifest themselves under load

About Minirobots

The Minirobots tool is an active multi-participant testing tool which simulates the behaviour of real traders.The tool has complete autonomy in making routine decisions under specific market conditions. Depending on what the testing needs are, each of the robots can act either orders.

The tool can be used for back-end testing by being connected to message gateways/APIs and databases of the systems being tested. GUI testing capabilities are also supported via plug-ins to other tools (e.g. Selenium).

Minirobots

  • Execute multithreaded java code
  • Allow the test developer to define the complexity of test algorithms
  • Support multiple client connections, order entry and market data via FIX
  • Can use GUI to iterate through sent and received messagesc

Test script

The test scripts are multi-threaded Java code. They allow the test developer to reproduce a variety of complex market scenarios according to the testing needs.

The Minirobots Skill Set

  • Market Making
  • ‘Slicing’ algorithms
  • Abusive market behavior
  • Realistic market environment
  • Test regression
  • Returning market data replay

Reference test harness for algorithmic trading platforms

The safety and stability of algorithmic trading software is an ongoing concern for exchanges, market participants and the society in general. Financial regulators
worldwide are trying to create effective rules to prevent selfenforced market volatility and technology crashes caused by computer-aided trading. Specifying relevant requirements for dynamic software verification of algorithmic trading platforms remains is an on-going task. Yet, there has been little progress to date in locating efficient and commonly accepted approaches. This paper introduces a reference test harness implementation for algo trading platforms created by the authors.

Trading Day Logs Replay Limitations and Test Tools Applicability

This paper is an experience report on replaying full trading day production log files for dynamic verification of securities exchange matching engines. Three types of test automation tools developed in-house are described along with their characteristics. The paper analyzes various approaches to reproduce processes and scenarios observed in the systems during their production usage. The applicability and limitations of these approaches are also considered. The authors point out that for most complex distributed real-time trading systems it is extremely difficult to obtain an identical behavior using production logs replay via external gateways. It might be possible to achieve this by implementing additional instrumentation inside the exchange system’s core. The authors assume however that such an intrusion has limited value and should not be prioritized
over other, more appropriate, test design methods for testing such systems.
