Add Additional Symbol
The Add Additional Symbol study allows the chart bar data for an additional symbol to be added to either a Historical or an Intraday chart in a separate Chart Region. The data is read directly into the chart. There is no need for a separate chart.
The purpose of this study is to visualize the bar data for another symbol within the same chart and also to perform custom calculations that involve the main price graph and the chart bar data for an additional symbol or multiple symbols.
It is essential when using this study to use Sierra Chart version 1694 or higher. This is a relatively new study and in previous versions, the study was still under development and there are some issues prior to this version with the Add Additional Symbol study.
Any number of Add Additional Symbol studies can be added to the chart to add more than one additional symbol to the chart.
The timeframe of each chart bar for the Add Additional Symbol study matches the timeframe of the main price graph bar for the same chart column. The timeframe of the main price graph chart bars can be any time frame including Number of Trades, Volume, Range, Reversal, Renko, Delta Volume, Price Change, Point and Figure Bars.
For example, if the main price graph chart bars are set to 60 minutes per bar, then each of the Add Additional Symbol study bars will be 60 minutes each and they will start and stop according to the same time frame as the bars of the main price graph.
The start time for any particular chart bar for the Add Additional Symbol study is the same as a start time of the bar in the same chart column. The end time for that part will be 1 second before the following bar in the main price graph. If there is no following bar because it is the last bar in the chart, the ending time is the Date-Time of the last trade within the last bar in the chart.
When the chart bars of the main price graph are based on a variable time frame like Number of Trades, Volume, Range, Reversal, Renko, Delta Volume, Price Change, Point and Figure Bars, then the timeframe of each chart bar for the Add Additional Symbol study matches the timeframe of the main price graph bar for the same chart column.
When an additional symbol has been added to the chart, the use of the Chart Values Crosshair and the displays in the Chart Values and Tools Values windows function as they do for other studies. For example, when using the Chart Values Crosshair, the displayed information in the Compact Tools Value Window will display the information for the area in which the crosshair is located. This will include the bar data for the Add Additional Symbol study if the crosshair is in the same Chart Region as that study.
The data for the additional symbol can be used directly in the Difference (bar) study. For more information refer to the Difference - Bar documentation. Specifically refer to the documentation for the Chart 2 Number and Graph Input.
The data for the additional symbol can also be used with any of the Arithmetic Studies.
Changes to the underlying data that that is used for the Add Additional Symbol study cannot be performed from the chart that contains the Additional Symbol. In order to make changes to the data, it is necessary to open the symbol directly in a separate chart and then make changes to the information there. Refer to Opening Chart. After you make those changes in a separate chart, then go back to the chart containing the Add Additional Symbol study and select Chart >> Reload and Recalculate.
To set the colors for the price bars displayed by the Add Additional Study graph, refer to Color Settings for Graph Draw Types.
Basing Other Studies on Add Additional Symbol
It is supported to base studies on the price graph for an Add Additional Symbol study.
The price data, Volume, Number of Trades, Bid Volume and Ask Volume are all available to the study being based on the Add Additional Symbol study. Number of Trades, Bid Volume and Ask Volume are only available for Intraday charts.
For instructions to base a study on another study, refer to the Based On setting on the Study Settings window.
Studies that require the underlying Volume at Price data will not have the Volume at Price data from the Add Additional Symbol study.
One example of this would be the Volume by Price study. Another example is the Volume Weighted Average Price study. However, in the case of Volume Weighted Average Price, you just need to set the Based on Underlying Data Input to No when it is based on the Add Additional Symbol study.
Updating of Additional Symbols in Chart
When using more than one Add Additional Symbol study in the chart, the real-time updating of them or updating of them during a chart replay does not occur until the historical data is complete for all of them.
- Symbol: This Input is for setting the additional symbol to be added to the chart. The symbols need to be the same format as the symbols listed in File >> Find Symbol.
In the case of when the chart is a Historical Daily data chart, the additional symbol will also be using the Historical Daily data for that additional symbol as well. If you want to use your own chart data file, then refer to the Text/CSV Data Format page. Make sure the file extension is .dly.
In the case of when the chart is an Intraday data chart, the additional symbol will also be using the Intraday data for that additional symbol as well. If you want to use your own Intraday chart data file, then it first needs to be imported into Sierra Chart. Refer to the Exporting and Importing Intraday Data Files page.
- Price Multipler: Defines the price multiplier value to be applied to the additional symbol's price. By default, this value is 1.
- Volume Multiplier: Defines the volume multiplier value to be applied to the additional symbol's volume. By default this value is 1.
- Fill Blanks With Last Value: When this is set to Yes any bar for a particular time that would not normally have any data present will use the values from the most recent previous bar that does have data. Otherwise, the chart column is left blank.
In most cases it is going to be essential that when using any of the Arithmetic Studies, that this Input is set to Yes so that there is data at each chart column which is necessary for these studies.
