Instrument Loading Functions:

Descriptions:

LoadSymbol

Loads an instrument's data into a BPV Instrument class variable. The instrument does not need to be in the current portfolio.  When it isn't in the portfolio, this function's parameter will allow Trading Blox Builder to find it and the instrument data file from where it is stored on the disk.  

 

This function is the method for accessing disk that don't have Automatic Instrument Context by default.  It is also for loading all or any of the instruments that have a specific Rank, or when the data is to added to an existing instrument's IPV variables.

 

To access and load an instrument this function supports the use of a:

osymbol

otype:symbol

ocurrent instrument index value

 

To load an instrument, it must be loaded into a BPV Instrument type variable.  It can't be loaded directly into an instrument object.  However, the data in the file loaded can be used as a source for adding information to an IPV property variable.

LoadSymbol is required to first load an instrument ahead of the execution of any of the following functions that can load by a specific value or need.
