How Expressions are accounted in DSWS request limits?

Hi,

For DSWS API i've found in the "DSWS user stats and limits" document this limitations for the getdata:

- Clients are required to stay under 10 million data points per month
- Maximum instruments per time series or snapshot request: 50
- Maximum datatypes per time series or snapshot request: 50
- Maximum instruments x datatypes cannot exceed 100

I was wondering how an expression is accounted, for example:

var expr = new DSInstrument("VOD(PL) + VOD(PH)", DSInstrumentProperties.IsExpression);
var datatypes = new DSDataTypes("X(MSVUSD)*x(MSFMCF)");

In the 1st example counts for 1 Instrument or 2?
In the 2nd example counts for 1 Datatype or 2?
What about data points count?

Thanks

To answer your questions:

  • In the 1st example counts for 1 Instrument or 2? Expression counts as one instrument.
  • In the 2nd example counts for 1 Datatype or 2? Expression counts as one data type.
  • What about data points count? Datapoints equal every data item returned. So number of series, multiplied by datatypes, multiplied by history.

HI,

Do we have the concept of unique Rics? Meaning if I get the historical data of FTSE 100 points three times per month. Is this would count as 300 or just 100 (unique)?
