Stock Price-Opining Tools

Gammath™ SPOT

Stock Price-Opining Tool is a DIY stock technical analysis tool used to analyze stocks and compute gScore that indicates the degree at which a stock is trading at a perceived discount or a perceived premium. The gScore is then used like an indicator in making buy, sell or hold decision on the stock.

How does it do that? It does this in two parts:

1. It provides a gammath_stocks_data_scraper.py app that scrapes the web to obtain stock information necessary to run its gScore computing algorithm
2. It provides a gammath_stocks_analyzer_and_scorer.py app that analyzes the stock data saved on the local storage from step 1 and computes gscores using its algorithm to indicate perceived discount or perceived premium
3. The gScores range between -1 and +1. gScores towards -1 indicates that the tool perceives the stock price to be at a premium while score towards +1 indicates that the tool preceives the stock price to be at a discount
4. Both the above apps take a watchlist as an input. A sample watch list is provided in sample_watchlist.csv [https://github.com/salylgw/gammath_spot.git] that can be used and updated for your watchlist

External dependencies

This project uses following free tools that need to be installed (you can use pip install) to be able to use this tool:

1. numpy
2. pandas
3. ta-lib (Install ta-lib using miniconda in case you run into problem: conda install -c conda-forge ta-lib)
4. yfinance
5. pykalman
6. statsmodels
7. sklearn
8. matplotlib
9. backtesting

WHERE to get source code without installing

Get source code from GIT repo git clone https://github.com/salylgw/gammath_spot.git

HOWTO install

pip install gammath-spot

In case you have trouble installing ta-lib then you can install miniconda and use conda install -c conda-forge ta-lib then run pip install gammath-spot

HOWTO use these apps

1. If you installed this software then run: gammath_scraper sample_watchlist.csv > log_scraper.txt
2. If not installed but just obtained the code then go to the directory gammath_spot/gammath_spot where all the source files are and run: python gammath_stocks_data_scraper.py sample_watchlist.csv > log_scraper.txt
3. Above step will save the scraper log in log_scraper.txt, creates a tickers sub-directory where it saves scraped data for stocks in the watch list
4. If you installed this software then run: 'gammath_scorer sample_watchlist.csv > log_scorer.txt`
5. If not installed but just obtained the code then go to the directory gammath_spot/gammath_spot where all the source files are and run: python gammath_stocks_analyzer_and_scorer.py sample_watchlist.csv > log_scorer.txt
6. Above step will save the scorer log in log_scorer.txt, analyze the stock data and computes the gScore using Gammath Works' algorithm
7. Go to ticker sub-directory and open overall_gscores.csv in your favorite spreadsheet program or a text editor
8. In overall_gscores.csv, you should see stocks from your watchlist arranged in ascending order of gScores. Lower values (towards -1) indicate that the tool perceives the respective stock to be trading at a premium while higher values (towards +1) indicate that the tool perceives the respective stock to be trading at a doscount. In this file, you'll also see sh_gscore (stock history based gscore) and sci_gscore (current info based gacore) that make up the overall gscore. If you are not interested in backtesting or sub-component score then you can ignore it These are the sub-components There is a lot of useful information stored in tickers/"ticker_symbol" dir that can be checked for details. "ticker_symbol"_signal.txt shows details of the analysis results and "ticker_symbol"_charts.png shows the plotted charts
