    Clarification on Last function in the AT interface

    Am very new to NT. Was trying to feed external data to NT7 using the AT interface, and it is mostly successful except that I ran into a few issues where I would appreciate some help:

    int Last(string instrument, double price, int size)

    1. If instrument is missing in NT, the return value is still a success (or 0)? That is, the return value just indicates if the values were sent to NT and not that the parameter is valid?

    2. When the size value is 0, NT seems to assume a value of 100 ?! Both a column in Market Analyzer and the historical database shows a value of 100 for ticks where the Last traded quantity is 0.

    TIA.

    Figured it out; it is an ATI API after all, not a quote data API.

    Sorry to have bothered you.
