TRADESTATION: MARCH 2020

In “Using Relative Strength To Outperform The Market” in this issue, author Markos Katsanos presents a trading system based on a new relative strength indicator he calls RSMK. The indicator improves on the traditional relative strength indicator by separating periods of strong or weak relative strength.

Below is the TradeStation EasyLanguage code for an indicator and strategy based on the author’s work. The strategy can easily be tested on a portfolio of favorite symbols using TradeStation’s Portfolio Maestro application.

Indicator: RSMK
// RSMK
// Mark Katsanos
// TASC March 2020
// Set up chart / application with
// reference symbol as Data2
// For example Data2 = SPY

inputs:
	Length( 90 ),
	EMALength( 3 ) ;
	
variables:
	StockPrice( 0, Data1 ),
	ReferencePrice( 0, Data2 ),
	LogVal( 0 ),
	RSMK( 0 ) ;
	

StockPrice = Close of Data1 ;
ReferencePrice = Close of Data2 ;

if StockPrice > 0 and ReferencePrice > 0 then
	LogVal = Log( StockPrice / ReferencePrice ) ;		

RSMK = XAverage( LogVal - LogVal[Length], 
	EMALength ) * 100 ;

Plot1( RSMK, "RMSK" ) ;

Strategy: RSMK
// RSMK
// Mark Katsanos
// TASC March 2020
// Set up chart / application with
// reference symbol as Data2
// For example Data2 = SPY

inputs:
	Length( 90 ),
	EMALength( 3 ),
	DaysToHold( 180 ) ;
	
variables:
	StockPrice( 0, Data1 ),
	ReferencePrice( 0, Data2 ),
	LogVal( 0 ),
	RSMK( 0 ) ;

StockPrice = Close of Data1 ;
ReferencePrice = Close of Data2 ;

if StockPrice > 0 and ReferencePrice > 0 then
	LogVal = Log( StockPrice / ReferencePrice ) ;		

RSMK = XAverage( LogVal - LogVal[Length], 
	EMALength ) * 100 ;

if RSMK crosses over 0 then 
	Buy next bar at Market ;
	
if BarsSinceEntry = DaysToHold then	
	Sell next bar at Market ;

METASTOCK: MARCH 2020

Markos Katsanos’ article “Using Relative Strength To Outperform The Market” in this issue introduces an alternative to the standard relative strength comparative indicator. The MetaStock version of the RSMK is shown here:

RSMK:
Formula:
rsbars:= Input("RS Bars", 10, 300, 90);
sk:= Input("Smoothing Constant", 1, 5, 3);
sec1:= Security("ONLINE:SPY", C);
sk2:= LastValue(Rnd(sk));
rs:= C / sec1;
Mov( Log(rs) - Log(Ref(rs, -rsbars)), sk2, E) * 100;

THINKORSWIM: MARCH 2020

We have put together a study as well as a strategy based on the article in this issue, “Using Relative Strength To Outperform The Market,” by Markos Katsanos. To ease the loading process of the study, simply click on https://tos.mx/X5HkInN or enter it into setup → open shared items from within thinkorswim, then choose view thinkscript and name it “RSMKstudy.” Do the same with https://tos.mx/aDKdOlc and name it “RSMKstrategy” to add the strategy to thinkorswim. These can then be added to your chart from the edit study and strategies menu within thinkorswim charts.

The screenshot in Figure 2 shows both the study and the strategy (with P/L graph) added to a three-year daily chart of ALGN. See Markos Katsanos’s article on how to properly interpret these.

WEALTH-LAB: MARCH 2020

This month’s issue promises an interesting new take on relative strength as presented in the article by Markos Katsanos. The author describes his new creature, the RSMK indicator, as offering many improvements over the traditional relative strength indicator such as simple and objective interpretation, the possibility to rank symbols, less lag, and other characteristics.

The long-only trading system presented here demonstrates how the RSMK can be put to use in both entries and different kinds of exits:

Entry

Buy next open when the RSMK crosses above zero

Exit

Sell when the RSMK falls by a certain amount of indicator points (20) off its 20-day high
Sell when the indicator crosses below its 20-day exponential moving average
Sell when it crosses below zero.

To execute this trading system, Wealth-Lab users need to install (or update to) the latest version of the TASCIndicators library from our website or using the built-in extension manager if you haven’t already done so, and restart Wealth-Lab. Once the new indicator is listed under the TASC Magazine Indicators group, it’s ready for use in Wealth-Lab.

QUANTACULA STUDIO: MARCH 2020

We’ve added the RSMK indicator, described in Markos Katsanos’ article in this issue, “Using Relative Strength To Outperform The Market,” to our TASC library so it is available both on Quantacula.com and in Quantacula Studio. The second parameter of the indicator is a string that represents the symbol of the index you wish to use in the indicator. The default value is “SPY.” The indicator automatically collects the data for the index and calculates the RSMK value.

FIGURE 8: QUANTACULA. This demonstrates the RSMK strategy mocked up using Quantacula Studio Building Blocks.

Shown in Figure 8 is the simple entry and exit rules for the strategy implemented as a Quantacula Studio Building Block Model. Using this approach, you can create a trading model without writing any code. You can even set the various parameters to be optimizable, and use Quantacula Studio’s optimizer to find the most profitable parameter ranges.

MICROSOFT EXCEL: MARCH 2020

In “Using Relative Strength To Outperform The Market” in this issue, Markos Katsanos improves on the commonly used relative strength (RS) indicator, which measures the performance of one security relative to another.

Background highlighting in Figures 12 and 13 demonstrates some of the subtle decision point differences between RS and RSMK

FIGURE 12: EXCEL, RELATIVE STRENGTH (RS). Here you see the comparative relative strength of ALGN with regard to SPY.

FIGURE 13: EXCEL, RSMK. Here’s an example of looking at periods of strong and weak RSMK of ALGN versus the SPY.

Background highlighting in Figures 13 and 14 demonstrates RSMK as a tool comparing the behavior of ALGN and NVDA.

Just to the right of the charts are the RS and RSMK values at the current far right cursor location.

Here’s a hypothetical question for you to consider: Say you had some free cash ready to invest today. Which of these two might you prefer? Note the following characteristics on the charts:

Both demonstrate recent upward price action.
The RSMK values for NVDA have been positive for some time.
The local RSMK values for ALGN show an upward trend out of the negative. And RSMK for ALGN has just crossed into positive territory on this bar. For this bar, ALGN also has a stronger RSMK value than NVDA.

Is this the beginning of an RSMK upward trend for ALGN? Or an RSMK whipsaw for ALGN? That is yet to be seen.

RSMK is very interesting. It will take a bit more playing with to see how to best fit RSMK into my trading strategies.

The spreadsheet file for this Traders’ Tip can be downloaded here. To successfully download it, follow these steps:

Right-click on the Excel file link, then
Select “save as” (or “save target as”) to place a copy of the spreadsheet file on your hard drive.

ERRATA NOTE:

On or slightly before January 20, 2020 Yahoo Finance changed the way splits are represented in downloads. Split representations went from using a slash (/) as the separator between the new shares and old shares numbers (ex. 3/2 or 2/1) to using a full colon as the separator (ex. 3:2 or 2:1).

This will cause a “Runtime error 9” in uncorrected code.

To fix: When you get the “error 9,” choose the debug option. This will take you into the VBA editor and highlight the failing VBA code line. Two lines above, you will find the line:

SplitFactors = Split(CsvColumns(CsvColNdx), "/")

Simply change the slash (/) to a full colon (:). Then close the spreadsheet with the SAVE option. Then open and run the spreadsheet.

Note: This problem exists in all uncorrected spreadsheets prior to March 2020.
