Code for the author’s indicators are set up in the EDS code file. Figure 7 shows the EDS module backtest results using the RSI original indicator. Figure 8 shows the EDS module backtest results using the modified version of the RSI indicator over a 10-year period using NASDAQ 100 stocks. The comparison suggests that some of the metrics improve using the modified version and a few are worse.
The system rules are:
Buy when the RSI crosses down below 20
Sell when the RSI crosses above 80 or after 20 trading days

In this article, Scott proposes a new adaptive moving average (AMA). It adjusts its parameters automatically according to the volatility of market, tracking price closely in trending movement, and staying flat in congestion areas. The new AMA is well-suited for swing trading.

Excerpt “Is there anything more satisfying for a trader than capturing a huge breakout? The usual practice for breakout entries is to simply buy new highs. This method, when used in isolation, will often result in false breakouts. It is, therefore, better to wait for volume confirmation before entering the trade, as high-volume breakouts usually last much longer. In this article, I will show you how to detect breakouts using only volume, sometimes even before price breaks out, by introducing a new volume breakout indicator. “

Synopsis from Stocks & Commodities June 2018
I’s it possible to create a stock rating system using multiple indicators or other technical criteria? If so, how does it compare with analyst ratings? Investors around the world move billions of dollars every day on advice from Wall Street research analysts. Most retail investors do not have the time or can’t be bothered to read the full stock report and rely solely on the bottom line: the stock rating. They believe these ratings are reliable and base their investment decisions at least partly on the analyst buy/sell rating. But how reliable are those buy/sell ratings? In this article I will present a technical stock rating system based on five technical criteria and indicators, backtest it, and compare its performance to analyst ratings.

Figure 11 shows the summary results of a backtest using NASDAQ 100 stocks during a generally bullish period from April 2009 to April 2018. Figure 12 shows the backtest using the same list of NASDAQ 100 stocks during a period that had two bear markets (April 1999 to April 2009). The average results are similar except that there are fewer trades during the period that contained the two bear markets. Both backtests use a fixed 21-bar exit.

The WinWay EDS code based on Vitali Apirine’s article in December 2017 issue of Stocks and Commodities magazine, “Weekly & Daily MACD,” is provided below.
The moving average convergence/divergence oscillator (MACD), developed by Gerald Appel, is one of the more popular technical analysis indicators. The MACD is typically used on a single timeframe, but what if we looked at two timeframes on one chart?
Traders can look for relative daily MACD line crossovers, weekly and daily centerline crossovers, and divergences to generate trading signals.
Figure 5 shows the daily & weekly MACD indicator on a chart of Apple Inc. (AAPL) during 2016 and 2017, when there was a change from a downtrend to an uptrend.

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 a WinWay 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:
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.
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.
