    Trading System Development using Amibroker

    United States - Tests: 1 - Portfolio: 2

    System developer, consultant and part time trader at InStat Research. Programming is done with Amibroker's AFL mainly although various scripting languages, C++, C# or Python have also been used. We can program basic indicators, trading systems, and various automation tools, such as automated trading or automated optimizations. We also develop extensions for Amibroker in order to automate manual tasks (i.e. updating databases) or to execute trades on other platforms. I have swing traded and daytraded the markets for years, including ETFs, stocks, bonds, forex, futures, options, mutual funds and know if a system just looks good but is non-tradeable because of liquidity, data or other problems. Our quote will be the maximum we will charge unless the client introduces new criteria once the project has started.
