Here’s a simple example of how to use Quantitative:

require "quantitative"

# Create a new series
series = Quant::Series.new

# Add some data to the series
ticks = [25.0, 26.0, 23.5, 24.5, 25.5, 26.5, 27.5, 28.5, 29.5, 30.5]
ticks.each { |tick| series << tick }

# Print the series
pp series

def current_date
  Date.today
end

.current_time ⇒ Object

The library is designed to work with UTC time. This method provides a single point of access for the current time. This is useful for testing and for retrieving the current time in one place for the entire library.
