Monte Carlo Stock/Crypto Price Simulation Tool

StockSim

Monte Carlo Stock & Crypto Price Simulation Tool

StockSim is a Python command-line tool for estimating the probability of gain for stocks, cryptocurrencies, or indices using Monte Carlo simulation and real historical data.

---

Features

• Simulate future price paths for stocks, crypto, or indices
• Uses real historical data via yfinance
• Multiprocessing for fast simulations
• Command-line interface

---

Requirements

• Python 3.7–3.12 (not compatible with Python 3.13)
• See requirements.txt for required packages

---

Installation

From PyPI (recommended)

pip install stocksim

From source

git clone https://github.com/ElementalPublishing/StockSim.git
cd StockSim
pip install -e .

After installation, run from the command line:

stocksim

Or, if running from source:

python -m stocksim.main

---

Command-Line Options

You can run StockSim with the following options:

• --symbol
  Ticker symbol (e.g., BTC-USD, ETH-USD, AAPL, SPX:IND, EURUSD:CUR)

• --years
  Investment period in years (e.g., 1)

• --simsize
  Simulation size: small, medium, or large

Examples:

stocksim --symbol BTC-USD --years 5 --simsize large
stocksim --symbol AAPL --years 3 --simsize medium

If you omit any option, the program will prompt you for input interactively.

Build Windows Executable (Optional)

To build a Windows executable with your custom icon:

pyinstaller --icon=shaggy.ico --name=StockSim stocksim/main.py

• The EXE will be in the dist folder as StockSim.exe.

---

Notes

• Compatible with Python 3.7–3.12, PyInstaller 5.13.2, and setuptools <80 (tested with 79.0.1).
• Note: Logging to files has been removed due to compatibility issues. All output is now printed to the console.
• For issues or feature requests, please use the GitHub Issue Tracker.

Note:
If you get a 'stocksim' is not recognized as an internal or external command error, you may need to add your Python Scripts directory to your system PATH.

For a typical Python installation on Windows, add:

C:\Users\<YourUser>\AppData\Local\Programs\Python\<Your Python Version>\Scripts

(Replace <YourUser> with your actual username and <Your Python Version> with your installed Python version, e.g., Python312.)

After updating your PATH, restart your terminal or Command Prompt and try running stocksim again.

Windows users: C++ Compiler Required

If you see an error like "Microsoft C++ 14.0 or greater is required," please install the Build Tools for Visual Studio.

Version Notes

• v1.3.3 is the last stable pure Python build.
  This version does not require a C++ compiler and is easiest to install on any system with Python 3.7–3.12.
  However, it lacks some of the advanced functionality and speed improvements found in later versions.

• v2.x and newer use Cython for much faster simulations and additional features, but require a C++ compiler (such as Microsoft Build Tools for Visual Studio on Windows) for installation from source.
