TRADERS’ TIPS
For this month’s Traders’ Tips, the focus is Barbara Star’s article in this issue, “The CAM Indicator For Trends And Countertrends.” Here, we present the January 2018 Traders’ Tips code with possible implementations in various software.
The Traders’ Tips section is provided to help the reader implement a selected technique from an article in this issue or another recent issue. The entries here are contributed by software developers or programmers for software that is capable of customization.
In the article “The CAM Indicator For Trends And Countertrends” in this issue, author Barbara Star introduces using chart patterns based on a coordinated ADX and MACD or, as she abbreviates it, CAM. In the article, she describes using the CAM indicator to identify upward and downward trends as well as pullbacks in existing trends and countertrend rallies.
Here, we are providing the TradeStation EasyLanguage code for the CAM indicator based on the author’s work. In a chart, the indicator will highlight the current pattern by painting the bar a user-defined color. In TradeStation RadarScreen, the current pattern will be shown in text.
The author also suggests using other indicators such as an exponential moving average (EMA) and the commodity channel index (CCI) to help confirm signals generated by CAM. These indicators are part of the standard library of analysis techniques included with the TradeStation platform and can be applied as desired.

The CAM indicator depicted by Barbara Star in her article in this issue, “The CAM Indicator For Trends And Countertrends,” combines two classic indicators, MACD and ADX, into a pair that intends to highlight the price patterns of trends and reversion.
As suggested in the article, trading this system should be approached after filtering out false pattern fluctuations by first checking the moving average and CCI indicator. The resulting countertrend system’s rules are:
Enter long: Buy tomorrow at open if today is a bar colored gold (which represents the CAM-PB, meaning the 10-period ADX and MACD are declining) but the 14-period CCI is above zero, or if today is a bar colored blue (that is, the 10-period ADX is declining but MACD rises) and today’s close crosses above the 13-period EMA.
Exit long: Sell tomorrow at open if today is a red-colored bar (which represents the CAM-CT; that is, the 10-period ADX is rising but the MACD is declining) and today’s close is below the 13-period EMA.
Nonetheless, filtering may not itself be enough; to maximize your odds, we recommend applying the system to a preselected watchlist of securities that demonstrate trendiness. Figure 3, which is of bitcoin, shows a characteristic example of an asset where a trend-following system that enters on corrections shines.

The CAM indicator patterns described by Barbara Star in her article in this issue, “The CAM Indicator For Trends And Countertrends,” can be easily implemented with a few of NeuroShell Trader’s 800+ indicators. Simply select new indicator from the insert menu and use the indicator wizard to set up the following indicators:
CAM-UP And2( A>=B(ADX(High,Low,Close,10,5), Lag(ADX(High,Low,Close,10,5),1)), A>B(MACD(Close,12,26), Lag(MACD(Close,12,26),1))) CAM-PB And2( A<=B( ADX(High,Low,Close,10,5), Lag(ADX(High,Low,Close,10,5),1)), A<B(MACD(Close,12,26), Lag(MACD(Close,12,26),1))) CAM-DN And2( A>=B( ADX(High,Low,Close,10,5), Lag(ADX(High,Low,Close,10,5),1)), A<B(MACD(Close,12,26), Lag(MACD(Close,12,26),1))) CAM-CT And2( A<=B( ADX(High,Low,Close,10,5), Lag(ADX(High,Low,Close,10,5),1)), A>B(MACD(Close,12,26), Lag(MACD(Close,12,26),1)))

The AIQ code based on Barbara Star’s article in this issue, “The CAM Indicator For Trends And Countertrends,” is provided at www.TradersEdgeSystems.com/traderstips.htm and is also shown below.
I created an indicator for the CAM that returns a “2” for the CAM_UP, a “1” for the CAM_PB, a “-1” for the CAM_CT, and a “-2” for the CAM_DN. I also created three buy rules and ran backtests.
FIGURE 5: AIQ. Here is an example of the ADX, MACD, and CAM_IND on a chart of NFLX.
Figure 5 shows the daily ADX and the daily MACD indicator together with the CAM_IND indicator on a chart of Netflix Inc. (NFLX) during 2017. The vertical line is an entry from the entry rule “BuyDNCT.” Of the three buy rules I tried, “BuyDNCT” showed the best backtest results with an average per trade of 0.62% over the past 48 months trading the NASDAQ 100 list of stocks and exiting after a nine-bar hold.

I created an indicator for the CAM that returns “2” for the CAM_UP, a “1” for the CAM_PB, a “-1” for the CAM_CT, and a “-2” for the CAM_DN. I also created a trading system that uses the CAM indicator and ran backtests.
Figure 6 shows the CAM_IND indicator on a chart of the S&P 500 futures contract (SP) for the last half of 2013. Several trades from the system are shown on this chart. Using optimization of cam1, cam2 and exitBars, I found the highest net profit from the system to be when cam1=-2, cam2=1, and exitBars =12. The equity curve from trading one SP contract is shown in Figure 7.

Manually creating highlight bars
If you would like to create these highlight bars manually, click on the edit dropdown
menu, open the trader’s toolbox (or use CTRL + T) and click on the functions tab.
Next, click on the new button, and a new function dialog
window will open. In its text box, input the code for the indicator. Ensure
that there are no extra spaces at the end of each line. When completed, click
on the verify button. You may be presented with an add inputs pop-up
message if there are variables in the code. If so, click the yes button,
then enter a value in the default value column. If all is well, when
you click on the function tab, the code you entered will convert to
italic font. Click on the save button and type a name for the highlight
bar.
Adding to your chart
Once they’re completed, you can insert the highlight bars onto
your chart by opening the charting dropdown menu, selecting the add
to chart command, then, on the highlight bars tab, find your
named highlight bar. Select it, then click on the add button. Repeat
this procedure for more highlight bars if you wish.
The “S&C CAM indicator” template can be inserted onto your chart by opening the charting dropdown menu, selecting the templates command, then selecting the “S&C CAM Indicator” template. You can apply the CAM study to your chart by opening the charting menu, selecting the add to chart command, and clicking on the studies tab. Here you will find the study in question. Select it by clicking on it, then click the add button.
Users may contact our technical support staff by phone or by live chat if any assistance is needed in creating or using the indicator or highlight bars.
A sample chart demonstrating the S&C CAM indicator template is shown in Figure 10.
FIGURE 10: TRADE NAVIGATOR. The S&C CAM indicator template is implemented on a sample chart.
Barbara Star’s article in this issue, “The CAM Indicator For Trends And Countertrends,” looks for patterns to be found in the relative behaviors of two well-known indicators—ADX and MACD.
In the article, Star shows a way of comparing them to pick out two main stages of market trend (up/down) and two market pause situations (pullback/countertrend) that might be interpreted as market indecision.
Star suggests that the addition of the CCI indicator and a 14-day moving average can assist when attempting to filter out false patterns.

The article “The CAM Indicator For Trends And Countertrends” by Barbara Star in this issue (January 2018 S&C) provides four custom formulas that are used to color the price bars that identify the CAM patterns. Given here are the steps to follow in MetaStock to color the CAM bars as described in the article.
Coloring the price bars as shown in the article requires that the formulas be placed in an Expert Advisor. The steps to follow are:
Creating the expert advisor:
Open the Expert Advisor. Click on new, give the Expert Advisor a name (for example, “CAM indicator”) then click the “highlights” tab.
Coloring the CAM-UP bars:
Select new from the menu on the right-hand side. This will open the experts highlights editor. Type in the name “CAM-UP.” Set the color option to green.
Type or paste the following custom formula into the condition box:
ADX(10)>=Ref(ADX(10),-1)AND When(MACD()>Ref(MACD(),-1))
Click OK.
Coloring the CAM-PB bars: Select new from the menu on the right-hand side. Type in the name “CAM-PB.” Set the color option to yellow. Type or paste the following custom formula into the condition box:
ADX(10)<=Ref(ADX(10),-1)AND When(MACD()<Ref(MACD(),-1))
Click OK.
Coloring the CAM-DN bars:
Select new from the menu on the right-hand side. Type in the desired name, “CAM-DN.” Set the color option to red. Type or paste the following custom formula into the condition box:
ADX(10)>=Ref(ADX(10),-1)AND When(MACD()<Ref(MACD(),-1))
Click OK.
Coloring the CAM-CT bars:
Select new from the menu on the right-hand side. Type in the desired name, “CAM-CT.” Set the color option to blue. Type or paste the following custom formula into the condition box:
ADX(10)<=Ref(ADX(10),-1)AND When(MACD()>Ref(MACD(),-1))
Click OK.
Click on the small checkboxes to the left of each pattern name (that is, CAM-UP, CAM-PB, CAM-DN, CAM-CT) to select the CAM patterns you want to see colored on the price bars (see Figure 1). Hit OK to create the Expert Advisor.
FIGURE 1: METASTOCK EXPERT ADVISOR. After entering the custom formulas into the condition box, click on the small checkboxes to the left of each pattern name (CAM-UP, CAM-PB, CAM-DN, CAM-CT, or however you have named them) to select the CAM patterns you want to see colored on the price bars.
