Does anyone know of a backtesting program I can use for strategy testing that will involve common indicators (MACD, RSI, etc.) plus astrological aspects, like relative positions of planets, etc.?
You can use this: http://www.cafeastrology.com/monthlycalendar.html (Make sure to scroll down the page. All kinda goodies in there!!!) You can also get "Daily Forecast Report" but it costs mula: http://www.cafeastrology.com/futureforecastreports.html with this: http://stockcharts.com/h-sc/ui?s=AAPL
You are not going to find any statistical significance in backtesting results that incorporate astrological aspects. Waste of time IMO.
