TASC 2018-01 | The CAM Indicator For Trends And Countertrends (Star)

Traders' Tip text

The CAM indicator depicted in the article by Barbara Star from January 2018 issue of Stocks & Commodities combines two classic indicators MACD and ADX into a pair that is believed to highlight the price patterns of trending and reversion.

As suggested in the article, trading this system should be approached after filtering out false pattern fluctuations by checking the the moving average and CCI indicator. The resulting countertrend system's rules are:

Enter long: Buy tomorrow at open if today's a “gold bar” (a.k.a. CAM-PB i.e. 10-period ADX and MACD declines) but the 14-period CCI is above 0, or if today's a “blue bar” (i.e. the 10-period ADX declines but MACD rises) and today's Close crosses above the 13-period EMA. Exit long: Sell tomorrow at open if today's a “red bar” (a.k.a. CAM-CT i.e. 10-period ADX rises but MACD declines) and today's Close is below the 13-period EMA.

Nonetheless, filtering itself may not be enough – to maximize your odds we recommend applying the system to a pre-selected watchlist of securities that demonstrate trendiness. Figure 1 shows a characteristic example of an 'asset' where a trendfollowing system that enters on corrections shines now – Bitcoin:

To make your conclusions regarding the efficiency of the indicator combo, run enclosed C# Strategy code (or simply download it from Wealth-Lab's “Open Strategy” dialog):
