## Markos Katsanos’s “Trading The Loonie”

Here is some code for use in AIQ based on Markos Katsanos’s article in this issue, “Trading The Loonie.” The code and EDS file can be downloaded from www.TradersEdgeSystems.com/traderstips.htm.

The code I am providing contains both the divergence indicator and a long-only trading system for the NASDAQ 100 list of stocks. Rather than trading forex, I wanted to try the divergence idea and the author’s entry rules on the NASDAQ 100 stocks. The stocks are traded long using the author’s entry rules with two of the parameters adjusted as shown at the top of the code file. The exit has been changed completely to use a profit protect (protect 50% of profits once a 20% profit is reached), a stop-loss (protect 75% of capital), and a time-stop exit (exit after 21 days). I used the NASDAQ 100 index (NDX) in place of the crude oil futures. The assumption is that since the stocks on the list are all in the NDX, they would generally be correlated to the index. The author’s entry rule filters out those with a negative correlation to the index. Note that I changed the minimum correlation from a -0.4 to 0.0. In addition, I found that increasing the minimum divergence from 20 to 2,000 increased the Sharpe ratio and decreased the maximum drawdown without affecting the annualized return.

Figure 6 shows the equity curve versus the NASDAQ 100 index for the period 1/5/2000 to 10/14/2015. Figure 7 shows the metrics for this same test period. The system clearly outperformed the index.

FIGURE 6: AIQ. Here is a sample equity curve for the modified divergence system versus the NASDAQ 100 index for the period 1/5/2000 to 10/14/2015.
