Volume-Weighted Moving Average Breakouts

The AIQ code based on Ken Calhoun’s article in the February 2017 issue of Technical Analysis ofSTOCKS & COMMODITIES, “Volume-Weighted Moving Average Breakouts,” can be found at http://aiqsystems.com/Volume-Weighted-Moving-Average-Breakouts.EDS 
 
Please note that I tested the author’s system using the NASDAQ 100 list of stocks on daily bars rather than intraday bars from 12/31/2008 thru 2/10/2017. Figure 7 shows the resulting equity curve trading the author’s system with the cross-down exit. Figure 8 shows the ASA report for this test. The annualized return showed about a 17% return with a maximum drawdown of 19%.

Exponential Standard Deviation Bands

back testing, EDS, Stocks & Commodities traders tips, technical indicator, trading strategy

The AIQ code based on Vitali Apirine’s article in the 2017 issue of Stocks & Commodities magazine, “Exponential Standard Deviation Bands”

Editor note: “Author Vitali Apirine presented a method intended to help traders see volatility while a stock is trending. These bands, while similar to Bollinger Bands, are calculated using exponential moving averages rather than simple moving averages. Like Bollinger Bands, they widen when volatility increases and narrow as volatility decreases. He suggests that the indicator can be used as a confirming indication along with other indicators such as the ADX. Here’s an AIQ Chart with the Upper, Lower and Middle Exponential SD added as custom indicators.”

 

 

To compare the exponential bands to Bollinger Bands, I created a trend-following trading system that trades long only according to the following rules:
  1. Buy when there is an uptrend and the close crosses over the upper band. An uptrend is in place when the middle band is higher than it was one bar ago.
  2. Sell when the low is less than the lower band.
Figure 8 shows the summary test results for taking all signals from the Bollinger Band system run on NASDAQ 100 stocks over the period 12/9/2000 to 12/09/2016. Figure 9 shows the summary test results for taking all signals from the exponential band system on NASDAQ 100 stocks over the same period. The exponential band system improved the average profit per trade while reducing the total number of trades.

Zero In On The MACD

EDS, Stocks & Commodities traders tips, technical indicator, trading strategy
The AIQ code based on Barbara Star’s article in May issue of Stocks and Commodities “Zero In On The MACD,” is provided at www.TradersEdgeSystems.com/traderstips.htm, and is also shown below.
Sample Chart

FIGURE 7: AIQ. Here is a sample chart of VIAB with MACDhist, the color bars, and the 34- and 55-bar EMAs.
Figure 7 shows the MACD histogram on a chart of Viacom (VIAB) with the color bars and the 34- and 55-bar exponential moving averages (EMA). Note that I did not code the weighted moving average (WMA) but substituted the EMA for the WMA. I chose to view the chart of VIAB by running the EDS “Zero MACD.eds” on 3/14/2016 and examining the alert messages on the report “List.” VIAB is the only one on that date that showed a cross up on the MACDhist (see Figure 8 for a look at part of this report for 3/14/2016).

Trading Gap Reversals

The AIQ code based on Ken Calhoun’s article in April 2016 issue of Stock & Commodities Trading Gap Reversals”, is provided below.

Since I mainly work with daily bar strategies, I wanted to test the gap-down concept on a daily bar trading system rather than on one-minute bars. I set up a system that buys after a stock has gapped down at least 10% in the last two days and then trades above the high of the gap-down bar. The entry is then at the close of that bar. For exits, I used the built-in exit, the profit-protect exit set at 80% once profit reaches 3% or more combined with a stop-loss using the low of the gap-down bar and also a time exit set to five bars. 
I then ran this system on the NASDAQ 100 list of stocks in the EDS backtester over the period 12/31/1999 to 1/11/2016 (Figure 7). The system generated 303 trades with an average profit of 1.09% per trade with a reward-to-risk ratio of 1.35. Slippage and commissions have not been deducted from these results.
