Buy and Sell Combinations
A buy and sell combination occurs when an investment is purchased on a given date and time and then sold on another date and time. The interval between the purchase and sale can be any unit of time.
A buy and sell combination results in a percent return that is a profit, loss or break-even.
Return = ((buy price - sell price) / buy price) * 100.
The formula used to compute the number of buy and sell combinations (returns) for a series of N prices is:
