I'd like to store computed properties of a stock in the Aux1, and Aux2 fields. Does anyone have a code example of how to use the OLE/COM features for doing this within an AA/Exploration? I could write out an ASCII file and then re-import it, but that seems to be rather brute-force. The properties I'm adding are computed using the OSAKA plug-in involving a large array for each stock - so I need to save the data (for use in a trading system).
