tsigna 0.1.0

Terminal tool to plot stocks, crypto, pair ratios, and technical indicators like MACD and RSI.

Tsigna

Tsigna is a Python financial analysis tool that runs entirely in the terminal. It is most useful for medium-term trading. It fetches historical stock data from Yahoo Finance, calculates technical indicators including moving averages, MACD, and RSI, and displays them as text-based charts using the plotille library. The tool supports single ticker analysis, ratio comparisons between two tickers, and a special MMRI calculation. Users can customize the time period and split the terminal display to show multiple indicators simultaneously.

Background

Originally I was looking for a free online tool to plot the ratio between two tickers, but I didn't find such a tool so I started working on Tsigna. The name comes from 'T' for terminal and the plural form of signum, the latin word for signal. The 'T' also stands for technical, like in technical indicators, from which we get technical signals.

Installation

Tsigna has been developped with Python 3.11 but may work with older versions. It depends on the pandas, plotille and yahooquery external libraries and their dependencies. They will all be installed automatically with the following command. It is recommended to make the installation within a virtual environment.

pip install tsignal

Configuration

You can edit the configuration constants directly at the top of the tsigna.py file if you wish to change the default behavior. For example you can change the expiration time of the cache (it is 5 minutes by default) or disable it. You can also change the colors of the lines, the parameters of the technical indicators, etc.

Not Financial Advice

I do not own any of the stocks in the examples, I chose them because they are very popular.

Acknowledgements

Tsigna is not doing much more than getting data from yahooquery, processing it with pandas, and plotting it with plotille, so thanks to the creators and contributors of these powerful libraries for making it possible.

Thanks also to the ticker tool, which is very useful to track prices in real time from the terminal.
