Excel For Trading: How To Do It Right
| 07:17:00 |
Wall Street uses Excel for trading on a daily basis. The average investor or trader doesn't use Excel this way, but the techniques for implementing Excel in a trading environment are relatively simple. You just need to know how you intend to use Excel, and what kind of trading workflow works for you.
One of the first considerations is how you will use Excel for trading. Will you be importing price data into a spreadsheet? Will you track your positions, profits, and losses there? Do you intend to integrate it with an existing trading platform? Do you want to develop a complete Excel for trading system with VBA, charts, order entry, and such?
There are a variety of functional options you can go with. Stock and futures watch lists are popular. These can be quite elaborate with multiple prices, colors, positions, profits, losses, etc. Real time or end of day P&L reports can be built to track your performance across trades. Tracking portfolio performance and attribution is another use. A trading log where you record your trade decision steps, emotions and results on each trade can help develop discipline and consistency. The main uses for Excel in trading include signal generation, risk and trade management. Many of these data points can be charted to provide a "one look" view.
Using Excel for trading is highly dependent on data. Importing prices and fundamental data into Excel automatically is a great first step to implement Excel for trading. In fact, not much else can be achieved until you import data, so this is a basic foundation step. There are multiple ways to do this. DDE links can be used to import data from a data vendor. Your broker's API can be used to connect to the actual prices your broker uses. Internal or vendor provided databases can be connected using SQL or web queries. How you implement the data import will have a lot to do with your strategy and the data types you want. For automated intraday trading with fast moving prices a DDE link is best. The Data from Other Sources function in Excel uses SQL Server, XML files or ODBC to connect to a database if you have one internally at your office or home. Web queries can work for end of day and fundamental quarterly type data. Economic data comes out infrequently so speed is not an issue.
Implementing Excel for trading requires planning your spreadsheet designs to integrate everything together correctly. The key things are having accurate and well tested formulas, and being able to find what you need when you need it. Multiple simpler spreadsheets linked together or a single large spreadsheet with multiple tabs are possible. You will likely have a mixture as you build out your spreadsheets. Keep in mind that it's easier to manage small workbooks with fewer tabs and they take up less memory and run faster. The ideal approach is to design in a modular way with each spreadsheet for a specific purpose. Be careful of external links, however. These can break and slow things down, and are difficult to debug if you have a lot of them. Also, if your spreadsheets have more than 10,000 rows of data, charts, and multiple tabs together then they may slow down. It's risky to have your whole trading workflow in one Excel file. Be sure to back up your files externally.
Considering these factors beforehand will help you put together the best Excel for trading layout to achieve your specific needs.
