Understanding the Drawdown & Streaks (DD) Feature

Hey guys! Let's dive into the exciting new feature: Drawdown & Streaks (DD). This feature is designed to help you analyze the performance of your trading strategies by looking at drawdown and streaks. This article will break down what this feature entails, how it works, and why it’s a crucial addition to your analytical toolkit.

What is the Drawdown & Streaks (DD) Feature?

The Drawdown & Streaks (DD) feature is a powerful tool designed to analyze financial data, particularly in the context of trading and investment strategies. It focuses on two key metrics: drawdown and streaks. Drawdown refers to the peak-to-trough decline during a specific period, while streaks indicate consecutive periods of gains or losses. By understanding these metrics, traders and investors can better assess the risk and consistency of their strategies. This feature computes the NAV curve, identifies rolling peaks, calculates drawdown curves, pinpoints top drawdown episodes, and determines up/down streaks for multiple OHLCV CSV files. In simpler terms, it helps you visualize and quantify the ups and downs of your investment journey, giving you a clearer picture of your strategy's risk profile and performance consistency.

This feature essentially gives you a detailed look at your trading performance. Think of it as a health check for your strategy. Instead of just looking at overall profit, it digs deeper into how you're handling risk and how consistently you're performing. We're talking about understanding your worst losing periods (drawdowns) and your best winning streaks. Knowing this helps you refine your approach and avoid potential pitfalls. It’s like having a weather forecast for your trading strategy, letting you prepare for both sunny days and stormy ones!

Key Components of the DD Feature

  • NAV Curve: Represents the Net Asset Value over time, giving you a clear picture of your portfolio's growth.
  • Rolling Peaks: Identifies the highest points reached by the NAV curve, crucial for calculating drawdowns.
  • Drawdown Curve: Visualizes the decline from peak to trough, highlighting the periods of maximum loss.
  • Top-N Drawdown Episodes: Pinpoints the most significant drawdown events, ranked by depth, length, and recovery time.
  • Up/Down Streaks: Tracks consecutive periods of gains or losses, indicating consistency and momentum.

CLI Usage: How to Run the Feature

The CLI (Command Line Interface) is your gateway to using this feature. It's a simple yet powerful way to execute the drawdown analysis directly from your terminal. Let's break down the command and what each part does.

The Command

dotnet run -- drawdown --symbols "AAPL=path,MSFT=path" --out out/dd --top 10

Let's dissect this command piece by piece:

  • dotnet run: This is the command to run a .NET application.
  • -- drawdown: This specifies that you want to use the drawdown feature.
  • --symbols "AAPL=path,MSFT=path": This is where you tell the tool which symbols (stocks, assets, etc.) you want to analyze. You provide the symbol and the path to the CSV file containing the data. For example, AAPL=path means you're analyzing Apple stock, and path is the file path to its data. You can include multiple symbols separated by commas.
  • --out out/dd: This specifies the output directory where the results will be saved. In this case, it's a folder named out/dd.
  • --top 10: This tells the tool to identify and report the top 10 drawdown episodes.

Understanding the Parameters

  • --symbols: This parameter is crucial. You need to provide the correct paths to your data files. The format is "SYMBOL=PATH,SYMBOL=PATH,...". Ensure that the CSV files contain OHLCV data (Open, High, Low, Close, Volume).
  • --out: This parameter determines where the results will be stored. Make sure the directory exists or the tool might throw an error. It’s a good practice to create an out directory in your project if you don't have one already.
  • --top: This is an optional parameter. If you don't specify it, the tool might report all drawdown episodes, which could be a lot. Specifying --top 10 or --top 5 gives you a manageable set of the most significant drawdowns to focus on.

By using this command, you're essentially telling the program to analyze the historical price data for the specified stocks, calculate the drawdowns, and save the results in CSV files. This data can then be used to further refine your trading strategies and risk management techniques.

Acceptance Criteria: What Makes it Work?

For this feature to be considered fully functional, it needs to meet certain acceptance criteria. Think of these as the quality control checks that ensure the feature is doing its job correctly. Let's break down these criteria:

Key Outputs

  • CSV Files: The feature should generate three key CSV files:
    • dd_curve.csv: This file contains the drawdown curve data, showing the fluctuations in equity during drawdowns.
    • top_drawdowns.csv: This file lists the top N drawdown episodes, ranked by depth, length, and recovery time.
    • streaks.csv: This file contains data on the up and down streaks, giving you insights into the consistency of gains and losses.
  • Return Code: The feature should return a 0 for valid inputs. This is a standard practice in command-line tools to indicate successful execution.

Core Functionality

  • NAV and Drawdown Calculation: The Net Asset Value (NAV) and drawdown should be computed accurately using Close-based daily returns. The NAV should start at 1.0, providing a standardized baseline for comparison.
  • Episode Identification: The feature should correctly identify peak and trough points in the data, which are crucial for determining drawdown episodes. It should also handle optional recovery periods, where the equity recovers from a drawdown.
  • Unit Tests: Robust unit tests are essential to ensure the reliability of the feature. These tests should cover various scenarios:
    • Parsing of input data
    • Handling monotonic zero-drawdown situations (where there are no drawdowns)
    • Accurate episode detection
    • Streak calculation
    • A smoke test to ensure the basic functionality is working

These acceptance criteria ensure that the Drawdown & Streaks feature is not only functional but also reliable and accurate. They cover the key aspects of the feature, from data processing to result generation, and provide a solid foundation for building trust in the tool's output. It’s like having a checklist to ensure everything is in order before launching a rocket – you want to make sure all systems are go!
