AIQ: SENTIMENT ZONE OSCILLATOR

Uncategorized

The AIQ code for Walid Khalil’s sentiment zone oscillator and related system from his article in this issue, “Sentiment Zone Oscillator,” is provided at www.TradersEdgeSystems.com/traderstips.htm.

Using the author’s system that is described in the article, I ran a
test on the NASDAQ 100 list of stocks using the Portfolio Manager
module. The following capitalization settings were used:

  • Maximum of 10 open positions
  • Size each position at 10% of mark-to-market total capital
  • Take no more than three new positions per day
  • Compute the mark-to-market capital each day
  • Choose signals based on a relative strength indicator for ranking in descending order for longs.

In Figure 9, I show the equity curve for long-only trading on the
NASDAQ 100 list of stocks for the period 12/31/1999 to 3/16/2012. The
return averaged 10.3% per year with a maximum drawdown of 56.5% on
3/9/2009. The trend filters that are applied to each stock in the system
did not prevent the large drawdown during the two bear markets in the
test period. Applying an index-based trend filter might improve the
results, but I did not try this due to time constraints.

The code and EDS file can be downloaded from www.TradersEdgeSystems.com/traderstips.htm and is also shown here.
