Terminology¶

Usage¶

• Keep domain-specific terms when they explain the quantity better than generic terms.
• profit is the accumulated financial result.
• gain is a positive or potentially useful increase between prices.

profit = 0

for i in range(1, n):
    gain = prices[i] - prices[i - 1]
    if gain > 0:
        profit += gain
