Excel For Trading Models - Using Excel's Capabilities To Make Money

By Carl Keenan


Professional traders use Excel on a daily basis to generate trading signals and manage trades. Average traders tend to rely only on charting programs or poorly designed and tested systems. Adding Excel to your repertoire can bring significant benefits in terms of control, efficiency and profitability. You just need to learn a few things about Excel and how to integrate it properly into your trading process.

You should first ask yourself how you might use use Excel for trading. Will you just import prices and volume data into a spreadsheet? Do you intend to generate buy/sell signals? How about tracking positions, profits and losses in a spreadsheet? Do you have an existing trading software platform you'd like to integrate with? Would you consider building a complete Excel for trading system with VBA, formulas, price imports and other features?

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.

Excel for trading depends on data. Once that's imported, what will you do with the data? Good options are watch lists, blotters, P&L statements, portfolio trackers, trade logs and heat maps. These can be used for intraday or historical analysis, trading performance, risk and trade management. Analytics like delta, drawdown, maximum adverse excursion, maximum profit realized or stop loss points can be calculated and displayed. There are unlimited uses of Excel for trading so feel free to let your imagination flow.

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.

These ideas should help you get started using Excel for trading to improve your trade processes and increase profits with less risk.
