You're now ready to run backtests with Anterior. The following example shows how to dynamically create a Fibonacci sequence by computing the next number every hour.

from anterior import BackTester

fibonacci = [0, 1]

def hourly_fibonacci():
    fibonacci.append(sum(fibonacci[-2:]))

bt = BackTester()
bt.every(hours=1).do(hourly_fibonacci)
bt.run(start="2021-01-01", end="2022-01-02")
