Identify The Start Of A Trend With DMI

Oct 22, 2012 | Uncategorized

The AIQ code based on BC Low’s article in the November issue of Stocks & Commodities, “Identify The Start Of A Trend With DMI,” is provided at the following website: www.TradersEdgeSystems.com/traderstips.htm, and is shown below.

Several of the terms used by the author had to be interpreted to be converted into signal code such as, “cluster drifts down below level 30,” “converging,” “turning up,” and so on. My interpretation may differ from what the author intended, and other interpretations are possible. In addition, I had to come up with exits for the signals as none were given. In testing using the NASDAQ 100 list of stocks, the long-only system was profitable over the test period, whereas I could not get the short-only system to be profitable.

To test the author’s 3x DMI system, I used the NASDAQ 100 list of stocks and AIQ’s Portfolio Manager. A long-only trading simulation was run with the following capitalization, cost, and exit settings:

  • 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
  • Three cents per share was deducted for each round-turn trade
  • Select trades based on the highest 14-bar ADX reading
  • Exit trades if the end-of-day stop-loss exceeds 3%
  • Exit trades by protecting 50% of profits once profit level reaches 10%.

In Figure 8, I show the resulting statistics and long-only equity curve compared to the NASDAQ 100 index. For the period 12/31/1999 to 9/17/2012, the system returned an average internal rate of return of 20.7% with a maximum drawdown of 58.2% on 3/9/2009.

A Seasonal Strategy With Leveraged ETFs

Sep 24, 2012 | Uncategorized

The AIQ code and EDS file for Gerald Gardner’s article in October 2012 Stocks and Commodities, “A Seasonal Strategy With Leveraged ETFs,” is provided at the following website: www.TradersEdgeSystems.com/traderstips.htm.

To test Gardner’s seasonal system with the leveraged exchanged traded funds (ETFs) DBC and DDM using AIQ’s Portfolio Manager, a trading simulation was run with the following capitalization and cost settings:

  • Maximum of two open positions
  • Size each position at 50 % of mark-to-market total capital
  • Take no more than two new positions per day
  • Compute the mark-to-market capital each day
  • Three cents per share was deducted for each round turn trade.

In Figure 7, I show the resulting statistics and equity curve compared to the S&P 500 index (SPX). For the period 9/1/2006 to 8/13/2012, the system returned an average internal rate of return of 13.7% with a maximum drawdown of 32% on 3/5/2009. These statistics differ from the author’s due to my test starting earlier, and also, I picked up three trades that the author did not show in his list of trades with returns of -15.4%, -8.0%, and 1.0%. These differences may be due to differences in our data. In my test, there were only 12 trades and I would like to see more trades before I would rely on this as a trading strategy. This is the problem with testing systems on ETFs — there is not enough data.

Market Log 9-18-2012 some signs of topping

Sep 19, 2012 | Uncategorized

The last market Expert Rating 10 days ago was 98-2. WAL (Weighted Action List) and the US (Unconfirmed SIgnals) show a different picture. The WAL analyzes all the high up and down Expert Ratings on the S&P500 that have been confirmed by an independent indicator, in this case the Phase (MACD based). For the 500 stocks analyzed, 24% have ratings to the upside and 76% to downside.

Interstingly the US shows a similar picture 18% have ratings to the upside and 82% to downside. The US is a raw picture of the percenatge of stocks in S&P500 with unconfirmed up vs down high Expert Ratings. Past analysis has shown this US balance is an early indication of a possible change when the balance reaches 15-85 or 85-15.

Emerging Chart Patterns 9-17-2012

Sep 17, 2012 | Uncategorized

Couple of chart patterns appeared in the Chart Pattern EDS report for 9-17-2012.

FEIC emerging pennant

FEIC had a sharp move up at the beginning of August and has since been forming a pennant pattern. The clarity, quality and initial trend for the pattern are very good. The length of the pennant part of the pattern is getting a little long in the tooth but still could resolve. Usually pennants are completed with a breakout to the upside through the upper trendline followed by an increase in volume.

TTMI merging ascending triangle

TTMI has a nice ascending triangle forming, the stock closed at 10.7 today and is still within the triangle. Diminishing volume is typical of this pattern. Breakout occurs usually to the upside through the horizontal trendline and needs to happen with good volume.
