Stock Calculation

When a share of common stock of some company is sold, the capital gain is the difference between the share's selling price and the price originally paid to buy it. This rule is easy to understand for a single share, but if we sell multiple shares of stock bought over a long period of time, then we must identify the shares acutally being sold. A standard accounting principle for identifying which shares of stock were sold in such a case is to use a FIFO protocol - the shares sold are the ones that have been held the longest(indeed, this is the default method built into several personal finance software packages). For example, suppose we buy 100 shares at $20 each on 1 day, 20 shares at $24 on day 2, 200 shares at $36 on day 3, and then sell 150 shares on day 4 at $30 each. Then applying the FIFO protocol means that of the 150 shares sold, 100 were bought on day 1, 20 were bought on day2, and 30 were bought on day 3. The capital gain in this case would therefore be 100 * 10 + 20 * 6 + 30 * -6, or $940. Write a program that takes as input a sequence of transactions of the form buy x shares at $y each or sell x shares at $y each assuming that the transactions occur on consecutive days and the values x and y are integers. Given this input sequence, thte output should be the total capital gain (or loss) for the entire sequence, using FIFO protocol to identify shares. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
