## Add your own stock and Wi-Fi info

1. Copy config.h.example to config.h.
2. Open config.h and set WIFI_SSID and WIFI_PASSWORD.
3. Add your API keys in config.h:
	- FINNHUB_API_KEY
	- ALPHAVANTAGE_KEY
4. Open m5paper-stockticker.ino and edit the myPortfolio[] list with your own symbols, share count, and total cost basis.

Portfolio format:
{ "SYMBOL", shares, costBasis, useAV }

- useAV = false for Finnhub (stocks and ETFs)
- useAV = true for Alpha Vantage (useful for some mutual funds)

## Device-specific note

This project is tuned for the M5Stack Paper S3 and its display size, rotation, and power behavior. Running it on another e-ink display usually requires extra configuration (display driver/init, resolution/layout coordinates, update behavior, and sleep/power handling) before it will render correctly.
