Recently I gave a presentation describing the process of creating and validating a simple trading strategy using AmiBroker. In this case, the instruments traded were the NIFTY and Bank NIFTY indices from the NSE in India, and the primary indicator used was the SuperTrend indicator. Although the performance results of the strategy are quite respectable, the real purpose was to introduce traders to the tools and methodologies that can be used to develop effective strategies of their own.
You can view the presentation linked above (my apologies for the less-than-stellar quality), or you can simply review the slide deck. As always, let me know if you have questions or comments. AFL used for the tests and an Excel workbook containing results are available upon request.
