# Create a format for the price change. This is an example of a conditional
# format. The number is formatted as a percentage. If it is positive it is
# formatted in green, if it is negative it is formatted in red and if it is
# zero it is formatted as the default font colour (in this case black).
# Note: the [Green] format produces an unappealing lime green. Try
# [Color 10] instead for a dark green.
