Stock-Pattern

A Python CLI scanner to detect and plot common chart patterns

Supports Python >= 3.8

If you ❤️ my work so far, please 🌟 this repo.

stock-pattern-cli

These were a series of pattern scanners I wrote for experimentation and fun in 2022. My inspiration was this Medium article Algorithmically Detecting (and Trading) Technical Chart Patterns with Python

Understand how the code works: wiki Pattern Algorithms

Important Info

All patterns are detected, prior to breakout. at the last leg of the pattern. Add the stock to your watchlist and track them further.

This program does not provide any buy or sell signals. It only detects the pattern. It is upto you to decide, if a pattern is valid or tradeable.

Installation

  1. Clone or download the repo:

    git clone https://github.com/BennyThadikaran/stock-pattern.git

  2. Install dependencies:

    pip install -r requirements.txt

  3. Setup configuration file with setup-config.py and answer the questions to generate a user.json

    py setup-config.py
    • Use direction keys to select a choice and press ENTER.
    • TAB key can be used to autocomplete filepaths. Use forward slashes / regardless of your OS to specify filepaths.
    • By default, filepath is mapped to your home folder /home/YourUsername on mac/linux and C:/Users/YourUsername on Windows.
    • You can use ../../ to go to C drive.

    Alternatively, I've written step by step instructions to create user.json manually

Usage

See Quick usage summary

See wiki Usage instructions

For backtest.py usage, see wiki backtest

Notes on structure of OHLC data

  • The following columns are expected: Open, High, Low, Close, Volume. Additonal columns may exist.

Disclaimer

This program identifies common chart patterns and does it reasonably well (IMHO).

Stock-Pattern is not aimed at replacing a trader's trained eye. It is merely an assistance and learning tool.

CLI options available, for you to backtest the patterns. If you intend to trade these patterns, study them well and trade at your own risk.
