Inky Stocks

A stock ticker for the Raspberry Pi Zero & Pimoroni Inky displays, fetching daily stock performance from the Yahoo Finance API:

• Supports any symbol on Yahoo Finance
• Displays the most recent day if the market is closed
• Works for 24/7 symbols like BTC-USD
• Plots the end of the previous day if the market opened <2 hours ago
• Supports both Inky pHAT (250x122) and Inky wHAT (400x300) displays

Setup

You'll need a Raspberry Pi Zero 2 (or WH) with either:

• Pimoroni Inky pHAT (250x122 version)
• Pimoroni Inky wHAT

Install the Inky library on your Raspberry Pi before running this script.

1. Activate your Python virtual environment, e.g. the default from the Inky pHAT install guide:

   source ~/.virtualenvs/pimoroni/bin/activate

2. Install the project dependencies:

   pip install -r requirements.txt

Example usage

Index	Stock	Crypto
python stocks.py --symbol ^FTSE	python stocks.py --symbol AAPL	python stocks.py --symbol BTC-USD

Multiple symbols (wHAT only)

# Show 3 major indices
python stocks.py --symbols ^GSPC ^FTSE ^DJI

Options

• Add the --three-color flag if you have a black/white/red variant of the display and you want the red highlights.
• Install the Pimoroni LED SHIM alongside the pHAT and it'll will light up green or red depending on whether the stock is up or down.
• You can test without hardware by running the display variant script directly (stocks_phat.py or stocks_what.py) with the same arguments. The screen output will be saved as a PNG.

Auto refresh

1. Create a bash script in the project directory and make it executable (touch run.sh && chmod +x run.sh):

   #!/bin/bash
   source ~/.virtualenvs/pimoroni/bin/activate
   python ~/inky-stocks/stocks.py --symbol ^FTSE --three-color

2. Add a cron job to run the script every 15 minutes:

   crontab -e

   */15 * * * * ~/inky-stocks/run.sh

Obviously this is just for fun, there are no guarantees about the accuracy of the data, and you shouldn't use this to make any financial decisions. :)
