FinancialInstrument functions output / side effect variables
Doug, I re-read your question. Let me clarify. Instruments are stored in an environment called .instrument at the top level of the package. You can see everything in that environment like this ls(FinancialInstrument:::.instrument) However, there are lots of functions show the primary_ids of instruments that do some checking to make sure that what is being shown are indeed primary_ids of instruments. e.g ls_stocks() ls_currencies() ls_instruments() Let me know if I can offer more clarity. Best, Garrett

Hi Doug,
You can use getInstrument to see the instruments
e.g.
stock("SPY", currency("USD"))
getInstrument("USD")
getInstrument("SPY")
Please take a look at the files in the demo directory
(https://r-forge.r-project.org/scm/viewvc.php/pkg/FinancialInstrument/demo/FIdemo2.R?view=markup&root=blotter)
You'll also probably be interested in ?buildHierarchy
build_series_symbols does nothing but return a character vector and it
does not store it anywhere and it does not create any instruments. (I
personally use future_id from the twsInstrument package to serve the
purpose of build_series_symbols)
HTH,
Garrett
