Plotting the Relative Strength Line in StockCharts

We have got this question alot recently: How do you plot the Relative Strength Line in StockCharts?

This blog post will walk you through the steps.

Stockcharts FREE accounts allow you to chart three indicators and this is enough to plot the Relative Strength Line over-layed with SPX in a style that is very similar to MarketSmith.

We won’t walk you through the registration process but we are sure you can figure that out for yourself at

Step 1: Set up your Chart Attributes

HLC Bars are achieve the same candle type as on MarketSmiths platform.
Time Span can be configured to your liking
Up Color: Blue
Down Color: Pink
Select: Log Scale, Color Volume, Smooth Lines

The Chart Attributes are personal preference.

Step 2: Depending on the level (if FREE) you can plot up to 3 Indicators / Moving Averages on the charts. (21, 50, 200DMA are typical Moving Averages that we like to use on our charts)

The Overlays are personal preference. Stockcharts allows you to set colors and opacity as well.

Step 3: Plotting the Relative Strength Line and SPX price action

In the Indicators Section, set the first Indicator to Price-Performance and for Parameters use the $SYMBOL:$SPX
This will allow you to compare “Symbols” to the $SPX which is the Relative Strength Line
We set the color to BLUE for the Price-Performance Indicator

Next, to plot the $SPX price line select Price from the Indicators drop down and then type in $SPX for Parameters.
To achieve a plot of the $SPX behind the Relative Strength Line we just plotted set the Position to Behind Ind.

That is it. You are all set.

Below we do a few comparisons on how this stacks up with MarketSmiths Relative Strength Line. Enjoy! 🙂

Note the Blue Relative Strength Line on MarketSmith and how it compares to what plotted on StockCharts. A very similar effect.
