Adding a custom Indicator that has been created using the RTL language to a chart is done with the indicator named Custom Indicator. The setup of the charted indicator is where the name of the RTL Custom Indicator is specified, along with other settings.
A general overview of custom Indicators can be found here.
For more information about how to create RTL Custom Indicators, see this article.
This video demonstrates how to manage the usage of the forward-looking Zig Zag Oscillator within a Custom Indicator or Signal Marker. The Zig Zag Oscillator is unique in that it is a forward looking indicator, and as such, past values can change based on future price movement. Due to this forward-looking nature, when the ZZO token is used within RTL, special consideration must be made to accommodate the addition of any Custom Indicators or Signals that contain ZZO when adding to a chart. This video describes how to setup such Custom Indicators or Signal.

Tokens are used with Investor/RT's Real Time Language(RTL) to access different types of data or True/False Conditions. You can use the search box below to search directly for a token name (if you know it already) or by a characteristic that you are looking for. Examples searches might be "Range" or "Volume" to reveal tokens related to those keywords. Tokens are also categorized into "Token Types" so that you can search by "Type." The list of Token Types include: Fundamental, Historical, Primitive, Technical Indicators, Alarm Flags, Monitoring Flags, Constants, Arithmetic, Relational and Logical. Tokens that relate specifically to trading typically have the prefix TR_. For example TR_FILL is the most recent fill price when in a position. For a full list of all trading related functions, see the article Trading Related Tokens. See also RTL Function Tokens for a list of all functions built-in to the RTL language.
The RTL Language has a special operator for conditional evaluation. The operator is designed to allow formulas where one result is desired in some cases and another result in other cases. For example, suppose you want to write a custom indicator formula where the value of the custom indicator is the maximum close in 5 periods for bars that close higher than they opened, but for bars that close at or below their open, the value is to be the minimum close in 5 periods. This kind of conditional formula can be cleverly written as:
Ergodic = TSI
Ergodic Signal Line = EMA(TSI)
Ergodic Oscillator = TSI - EMA(TSI)
By default, TSI, the True Strength Index is setup with a Short Term of 5 and a Long Term of 20 and EMA is setup with a period of 5.

Experience Level - Novice This video describes how to combine RTL tokens to form syntax. Several examples of syntax are provided for both custom indicators and signals. This video also explains how to edit technical indicator token preferences within saved RTL objects.
