print(max_three_days.next(4)) # >> 4
print(max_three_days.next(2)) # >> 4
print(max_three_days.next(5)) # >> 5


min_three_days = fc.Minimum(3)

print(min_three_days.next(1)) # >> 1
print(min_three_days.next(4)) # >> 1
print(min_three_days.next(2)) # >> 1
print(min_three_days.next(5)) # >> 2


sma_three_days = fc.SimpleMovingAverage(3)

print(sma_three_days.next(1)) # >> 1
print(sma_three_days.next(4)) # >> 2.5
print(sma_three_days.next(2)) # >> 2.33
