The AIQ code based on Perry Kaufman’s article in the June 2014 Stocks & Commodities magazine, “Slope Divergence: Capitalizing On Uncertainty,” is provided at
www.TradersEdgeSystems.com/traderstips.htm.
I have modified the implementation somewhat from the author’s descriptions. I did not find that the system was exiting in an average of six days but was holding for a longer period. My exits might be the issue so I added a time exit that can be used to force an exit after the “maxBars” input number of bars. I liked the results when my time exit was set to hold for a maximum of nine bars.
Figure 7 shows the AIQ EDS summary long-only backtest report using the NASDAQ 100 list of stocks over the prior four years ending 4/10/2014. Neither commission nor slippage have been subtracted from these results. To get the short side of the system to show a profit, I added slope filters on the NASDAQ 100 index. Note that my parameter settings differ from those suggested by the author.
