An example of how to use the Option Chain Provider
The OptionChainsProvider (OCP) class provides access to a collection of options for an underlying asset. The collection that is returned includes options that satisfy the criteria established in the OCP properties.
This tutorial gives a straightforward example of how to use the OCP in the hope that you will be able to program more complex examples.
The tutorial program consists of three main methods:
- A method to create a new OptionChainProvider (OCP). The method is called for @ES. The number of expirations is set to 1 and the number of strikes to 2.
- A method to create a Price Series Provider (PSP) for a specified symbol.
- A method to print some information about the symbols in the OCP and to create a PSP for each symbol (by calling the method described in number 2). The PSPs are stored in a dictionary.
The program then plots the information for the PSPs in 8 plot statements.
As of May 2019, the TradeStation 10 Object Reference states that: “These classes and associated documentation are preliminary and may be changed before the OCP is formally releases.”
This tutorial program does not have any inputs.
- Creating and using methods
- Creating an Option Chain Provider using a method
- Printing a snapshot of information about the options identified by the OCP
- Creating multiple Price Series Providers using a method
- Storing PSPs in a dictionary
- Plotting the closing values of PSPs

Code snippet used to set the Options Chain Provider to local or exchange
// Determine if the chart is set to local or exchange time using the DataStreams Class if AnalysisTechnique.DataStreams.Stream[DataNum].TimeZone = tsdata.common.TimeZone.exchange then OCP.TimeZone = tsdata.common.TimeZone.exchange else OCP.TimeZone = tsdata.common.TimeZone.local;
