TradeStation: August 2021

In “Moving Average Bands” (part 1, July 2021 issue) and “Moving Average Band Width” (part 2, August 2021 issue), author Vitali Apirine explains how moving average bands (MAB) can be used as a trend-following indicator by displaying the movement of a shorter-term moving average in relation to the movement of a longer-term moving average. The distance between the bands will widen as volatility increases and will narrow as volatility decreases. In part 2, the moving average band width (MABW) measures the percentage difference between the bands. Changes in this difference may indicate a forthcoming move or change in the trend.

Provided here is the EasyLanguage code for both MAB and MABW.

thinkorswim: August 2021

We have put together a couple of studies based on a pair of articles by Vitali Apirine appearing in the July 2021 issue (“Moving Average Bands, part 1)” and August 2021 issue (“Moving Average Band Width, part 2).” We built the indicators referenced in the articles by using our proprietary scripting language, thinkscript. To ease the loading process, simply click on http://tos.mx/jSJKR4c or enter it into the address into setup→open shared item from within thinkorswim then choose view thinkScript study and name it “MovAvgBands” or a name you like and can identify it by. The second study for the moving average band width can be found from this link: http://tos.mx/OZr9CI5. Follow the same instructions as for the first study, but label it with the name “MovAvgBandWidth.”

Figure 2 shows the MovAvgBands as an upper study and the MovAvgBandsWidth as a lower study on a 15-year weekly timeframe chart of SPX. Please see the articles by Vitali Apirine for more information on how to interpret these studies.

Wealth-Lab.com: August 2021

We have added the moving average bands and moving average band width indicators to Wealth-Lab 7 for the convenience of our users. We’ll show how Wealth-Lab’s building blocks feature makes it easy to set up trading systems. For a description of the two indicators, see Vitali Apirine’s articles in this issue (August 2021 issue) and last month’s issue (July 2021 issue).

The first example system demonstrated here, which is a simple trend-following system using MA bands, is based on the premise that the moving average band boundaries can be used to help identify uptrends and downtrends:

Example system 1 rules

Figure 4 demonstrates using Wealth-Lab’s building blocks for the example system. Figure 5 shows a chart of the referenced bands plotted on the SPY.

Sample Chart

FIGURE 4: WEALTH-LAB. This shows an example of constructing example system 1 by using Wealth-Lab’s building blocks feature.

Sample Chart

FIGURE 5: WEALTH-LAB. This chart shows some sample trade signals for example system 1 on a chart of SPY.

Band width indicators help identify consolidation patterns, which may lead to powerful breakouts. Typically, consolidation manifests itself as a narrowness followed by a short moving average cross above the upper band. As such a pattern takes some time to form, it may have already ended by the time a breakout happens.

The time diversity of the two events usually makes programming the idea less straightforward. But in Wealth-Lab, users can quickly build the trading system without having to code as follows:

Example system 2 rules

Figure 6 demonstrates using Wealth-Lab’s building blocks to set up the MABW indicator. Figure 7 shows an example of implementing the MABW indicator on a chart of SPY.

The Zorro Project: August 2021

Compared to plain indicators, bands have the advantage that they look more colorful on charts. Additionally, they offer two more lines for triggering trade signals. In his article in the July 2021 issue, “Moving Average Bands (part 1),” Vitali Apirine presents a variation on Bollinger Bands based on the difference between two exponential moving averages. The code in C to recreate the described bands for use on the Zorro platform is as follows:

var MAB(int Period1,int Period2,var Mltp)
{
  var MA1 = EMA(seriesC(),Period1);
  var MA2 = EMA(seriesC(),Period2);
  var Dst = MA1-MA2;
  var Dv = SMA(series(Dst*Dst),Period2);
  var Dev = sqrt(Dv)*Mltp;
  rRealMiddleBand = MA1;
  rRealUpperBand = MA1+Dev;
  rRealLowerBand = MA1-Dev;
  return MA2;
}

The three variables rRealMiddleBand, rRealUpperBand, rRealLowerBand are predefined variables for band indicators. Here is code in C to replicate the author’s chart:

function run()
{
  StartDate = 20111201; 
  EndDate = 20130815;
  BarPeriod = 1440; 
  LookBack = 300;
	
  asset("NAS100");
  var Signal = MAB(200,50,1);
  plot("MA2",Signal,LINE,BLUE);
  plot("MAB1",rRealUpperBand,BAND1,RED);
  plot("MAB2",rRealLowerBand,BAND2,RED|TRANSP);
}

This code generates the chart shown in Figure 14 of the Nasdaq index from 2012 to mid-2013 with the parameters (200,50,1) for the slow and fast MA and the deviation multiplier.

Sample Chart

FIGURE 14: ZORRO PROJECT. Moving average bands are shown on a chart of the Nasdaq index from 2012 to mid-2013 with parameters (200,50,1) for the slow and fast MA and the deviation multiplier.

The blue line is the fast MA. The author suggests using the crossing of this line with the upper and lower band for buy and sell signals. We can put that to the test by adding the following code:

vars Signals = series(Signal);
MaxLong = MaxShort = 1;
if(crossOver(Signals,rRealUpperBand))
  enterLong();
if(crossUnder(Signals,rRealUpperBand))
  exitLong();
if(crossUnder(Signals,rRealLowerBand))
  enterShort();
if(crossOver(Signals,rRealLowerBand))
  exitShort();

Figure 15 shows the equity curve from 14 trade signals between 2011 and 2021 using the same MAB parameters shown in the article. This bumpy system would require strong nerves, since it twice lost almost all its capital. But as the author states in his article, you need a lot more indicators on your chart when you really want to trade with moving average bands.

Sample Chart

FIGURE 15: ZORRO PROJECT. A sample equity curve is shown from 14 trade signals between 2011 and 2021 using the same MAB parameters.

In part 2 of the article (“Moving Average Band Width”) in this issue, Vitali Apirine suggests using the width of the band as an additional indicator for helping to spot trend changes or consolidations. The following additional code plots the band width and its lowest value within the last slow period:

var Bndw = 100*(rRealUpperBand-rRealLowerBand)/rRealMiddleBand;
plot("Width",Bndw,NEW|LINE,RED);
plot("Low",MinVal(series(Bndw),200),LINE,BLACK);

The chart in Figure 16 displays the band width (red) and its 200-day low (black) in the additional window below the main chart.

Sample Chart

FIGURE 16: ZORRO PROJECT. The band width (red) and its 200-day low (black) are displayed in the window below the main chart.

The MA bands indicator and sample system can be downloaded from the 2021 script repository on https://financial-hacker.com. The Zorro platform can be downloaded from https://zorro-project.com.

Microsoft Excel: August 2021

The spreadsheet given here is based on Vitali Apirine’s articles on moving average bands and moving average band width (July 2021 and August 2021 issues).

The lookback periods used in the article’s examples suggest that these indicators are aimed at taking a longer view of trending and sideways market periods while ignoring or smoothing over the smaller gyrations.

The two-part article provides us with examples using daily and weekly bars. However, the logic involved will easily accommodate bars at much smaller intervals. So if you have such data available, it should be worth your time to explore at that level.

Trying to cram both indicators into the chart space of my template can make some details difficult to see. But it is worthwhile to see how the significant indicator features play out next to each other (Figure 19). Then, using the buttons to the right of the charts, you may drill down on either indicator as in Figures 20 and 21.

Sample Chart

FIGURE 19: EXCEL. This shows an approximation in Excel of Figure 4 from Vitali Apirine’s article in this issue.

Sample Chart

FIGURE 20: EXCEL. This shows moving average bands (MAB) on a chart in Excel.

Sample Chart

FIGURE 21: EXCEL. This shows the moving average band width (MABW) indicator on a chart in Excel.

While not specifically mentioned in the article, the MetaStock code sidebar contains a scaling factor provision labeled MLTP, which was set to 1. If you have a chart where the bands run close together and it is difficult to see where the short-term average is in relationship to the bands, I found that using a larger MLTP value of 3 or 4 could be used to spread the bands out for a better visual. This indeed increased the values seen on the y-axis for both the bands and the band width charts.

Interestingly, because of the dynamic axis scaling used here, with a larger multiplier value applied, the shapes created by the lines on the band width chart are larger in terms of absolute value but look the same.
