#
# This utility sets the ticker symbols that the TurboLEDz stock ticker will retrieve.
# Default set that the device ships with is comprised of the corporations in the DOW30 index:
#
# Only works with:
#   * ticker symbols of length 4 or shorter.
#   * equities/ETFs but not mutual funds.
#   * symbols without a dot character (E.g. HOT.UN or RY.TO not allowed.)
#   * up to 30 symbols.
#
# Sample usage:
#   ./set_ticker_portfolio.py 10.0.99.127 RBLX SBRA MCD AAPL UAN PFE NYMT EBF BGSF TG PAC INN BROS VYM
#
# If less than 30 symbols are supplied, the list is padded with DOW30 stocks.
