    Automated system discovery, not manual strategy building

    GSB finds the indicators that suit your market and builds complete systems automatically. No guessing which indicators to use—let the data decide.

    Genetic Algorithm Discovery
    Genetic Algorithm Discovery
    GSB uses genetic algorithms to search combinations of its built-in indicators, entry types and parameters, building and back-testing thousands of candidate systems for your market.
    Walk-Forward Optimization
    Walk-Forward Optimization
    Walk-forward test candidate systems inside GSB. The equity graph marks each walk-forward in-sample/out-of-sample boundary, so you can see how a system held up on data it was not optimised on.
    Comprehensive Validation
    Comprehensive Validation
    Check systems on out-of-sample dates and on verification data (other markets, or price data with random noise added), with performance filters that reject systems that don't hold up.
    Multi-Platform Export
    Multi-Platform Export
    Copy a selected system's code from the Scripts tab into TradeStation, MultiCharts or NinjaTrader 8, then check the platform results match GSB.
    Fully Automated Building
    Once GSB is set up for your data, it builds and ranks systems unattended. Macros (and the optional GSB Automation add-on) can automate repeated tests.
    Multi-Market Validation
    Add verification price data for related markets or timeframes and see how each system performs on them.
    Smart Constraints
    Set guardrails to guide the search toward realistic systems, but let the computer do the discovery.
    Complete System Analysis
    Performance statistics, equity graphs, trade lists and parameter stability scores for each generated system.

    Fully automated system discovery

    GSB finds the indicators that suit your market, checks them out of sample, then builds complete trading systems—all while you focus on trading.

    01

    Discover Best Indicators

    GSB builds systems from its library of built-in indicators, then its Statistics tab shows which indicators appear most in the best systems for your market—not what you think should work.

    02

    Validate Out of Sample

    Check the indicator statistics on out-of-sample dates, and keep only the indicators that hold up for the next build.

    03

    Build Complete Systems

    GSB builds complete trading systems from the chosen indicators, with their parameters optimised during the build.

    04

    Test Robustness

    Walk-forward testing, parameter stability scores and verification on other markets help you spot systems that are curve-fit.

    05

    Export Code

    Copy the system's code for TradeStation, MultiCharts or NinjaTrader 8 from GSB's Scripts tab.

    06

    Verify and Paper Trade

    Check the platform results match GSB, then paper trade before you consider trading live.

    Example Output

    What GSB produces

    Example equity curves from systems built with GSB and walk-forward tested. Where marked, the out-of-sample section is data the system was not built on.

    GSB Pro is an authorised GSB reseller. Trademaid issues every GSB licence and trial, so signing up there means you get the official installer, your licence and forum access straight from the source—with no double registration.

    Licences and add-on tools are purchased on Trademaid. Use the "Buy on Trademaid" buttons on the Pricing page; final pricing is confirmed at checkout.

    GSB generates system code for TradeStation and MultiCharts (EasyLanguage, using GSB's functions, which you import from File > Supplementary Scripts) and for NinjaTrader 8 (NinjaScript). Copy the code from the Scripts tab, then check the platform's results match GSB before trading.

    You can hold back out-of-sample dates, walk-forward test systems, and add verification price data (other markets, or your market with random noise added) so you can see whether a system still works on data it wasn't built on. Systems that hold up only on the build data are likely curve-fit.

    GSB is a development and validation tool. After generating and validating strategies, you export clean code to your trading platform for paper trading verification, then live deployment. Always verify exported code matches backtest results.

    The GSB Pro Members Area holds training videos and tutorials for GSB users. Your GSB licence itself, downloads and updates come from Trademaid.

    No programming required. GSB uses genetic algorithms to generate strategies automatically. However, understanding basic trading concepts and validation principles will help you use the tool effectively.
