This video discusses a new concept introduced in Investor/RT 12.2: Chart Variables or C# Variables. Unlike User Variables (V#1,...V#512), Chart Variables are not associated with a specific instrument (ticker) but with a specific chart. The RTL language and indicator setup dialogs support these C# variables, C#1,...C#32. Chart variables may be used in the same places as V# variables are, typically as variables/periods within indicator settings.
This video illustrates how to use reference lines based on V# variables to set high and low alarms for a variety of symbols directly in a chart. This method also works well for reference lines based on High and Low Alarm levels.
Every symbol has up to 512 available User Variables (V#1, V#2, ... V#512) which can be used to store data specific to that symbol. User Variables have become useful in a variety of ways in Investor/RT. As quotepage columns, their values can be adjust manually directly in the quotepage cell. Values can be set for an entire quotepage with a single scan (e.g. SET(V#1, CCI)). Reference lines can be attached to user variables. Each variable can be assigned it's own custom title (which shows up in quotepage columns) and display format (2 decimal, 32nds, etc).
Today's tip will cover the use of V# variables in QuotePages, Scans, Custom Indicators, and Trading Signals. Additional Information on Setting V# Variables can also be found in the Scan Tutorial.
