In this tutorial, we build a complete quantitative backtesting workflow with OctoBot and OctoBot-Script while keeping the environment isolated from Colab’s preinstalled dependencies. We configure a rule-based trading strategy that combines RSI-based oversold signals, EMA trend confirmation, and ATR-driven adaptive stop-loss and take-profit levels, and we execute it through OctoBot’s native market-order and backtesting APIs. We also retrieve historical OHLCV data through OctoBot’s data layer with automatic exchange fallback, perform a multi-parameter grid search over an in-sample period, and select the strongest configuration based on its excess return relative to buy-and-hold. We then validate the selected parameters on a completely separate out-of-sample period to assess generalization and identify potential overfitting. Finally, we extract OctoBot’s backtest report data and use Pandas and Plotly to analyze parameter sensitivity, portfolio performance, price action, indicators, and execution results in an interactive Colab environment.
