Trading Blox Builder has three Instrument and one System property that can be used to know the data class specified by the system's selected portfolio.

 

Instrument Object: .isForex, .isFuture, & .isStock

System Object:  .portfolioType

 

These instrument properties and the system property return the asset class of the instrument. The instrument asset class is assigned during data load phase of a system/suite test.  Result returned is based on which of the selected data class options is selected.  

 

Instrument properties return a TRUE, " 1 ", or a FALSE, "0"

 

For example, stocks can be loaded from the stock dictionary, or directly from the data file.

Futures and Forex instruments are loaded from the Forex or Futures Dictionaries.  

Any instrument loaded from a dictionary will be assigned that dictionary's class designation.  

 

The System object property called “portfolioType” that returns the portfolio selection, stock, futures, or forex.

System property will return a string result

  FX = Forex
  F = Future
  S = Stock
