Check and change existing EXCEL sheet

I need an EXCEL sheet for accounting of monthly and yearly stock market results. Parts of it (three graphs and two or three calculations) are an emergency, as I need them until June 14th. So there are two parts of work, one that has to be completed until June 14th and one after this date. There are some specific stock market formulas like "Sharpe Ratio" in this sheet that need to be calculated automatically. I have a version of this sheet (see attached file) that needs to be supplemented and simplified to make it easier to work with. There are some quite complex functions that call other functions. You may use them or build your own solution. Regarding the fees (one function of the sheet), the user can choose between four options for different outputs: Monthly and yearls compound or not compound results. This feature is already in place. It will be your task to doublecheck the existing features and stock market formulas (see attached) and create a modified or new sheet (or seperated EXCEL solutions if necessary), with the following main features: - a simple function to get single months returns from a row of added returns and vice versa in two options: absolute and relative [login to view URL]: input is 100.00, 102.50, 101.34, 105.75 and output should be 2.50, -1.16, 4.41 etc. - input section where the monthly results can be filled in easily with pre-set years (e.g. 1980 until 2020) where only the years that are filled with numbers by the user appear in the output tables and graphs. The silly EXCEL function where numbers are automatically converted to calendar dates should be excluded. - the four existing graphs (see attached) in a doublechecked version. - the performance graph with a function to either display it with or without benchmarks. I will provide you with the necessary stock market formulas. Similar calculations and graphs can be seen on [login to view URL] . ## 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.
