BacktestingXL Pro is an add-in for backtesting your trading strategies in Microsoft Excel 2010.It enables you to test and evaluate end-of-day trading strategies using historical data.

Users can use VBA (Visual Basic for Applications) to build strategies for BacktestingXL Pro.However, VBA knowledge is optional - in addition to using VBA-constructed trading rules, you can construct trading rules on a spreadsheet using standard pre-made backtesting codes.
BacktestingXL Pro supports advanced functionality, such as pyramiding (change of position size during an open trade), short/long position limiting, commission calculation, equity tracking, out-of-money controlling, buy/sell price customizing (you can trade at Today's or Tomorrow's Open, Close, High or Low prices).

Such functionality enables you to build "natural" trading strategies and prevents you from putting your strategies in "frames."
