Request Syntax

This is pretty much according to standing GT symbology (see the GT help file symbology.hlp).

Navigation information (which represents a list of indices and sectors of which that instrument is a constituent, alternative listings for that instrument, and so forth) is accessed by requesting the instrument named in the "NAV" field (usually just the instrument name suffixed with "/NAV", e.g. "ICI.L/NAV").

The GlobalTOPIC Feed symbology is designed to be consistent across types of instruments and to be intuitive for users.

Broadly, the symbology rules are the following:

For currencies, the GlobalTOPIC symbology uses the ISO currency codes (ISO 4217) with 2 additions - GBX for pence Sterling and USX for American cents. If the base currency (or, for Sterling, which is quoted inversely, the main currency) is the US Dollar, then this is omitted, although the delimiter is still used. The delimiter for currencies is a "/", e.g."GBPCAD/" is the UK Pound against the Canadian Dollar.

For security and company records, the symbology is the Datastream security or company number with a .SEC or .COM suffix respectively.

Notes

1. For indices not sourced from an exchange, the exchange suffix is omitted, but the . is retained, e.g. �=DJI.

2. For Futures, the month code (indicated in the syntax by �M�) is a single character, as follows:

The Year code (indicated in the syntax by �Y�) denotes the expiry year. This can be either:

1 digit

Representing the last digit of the expiry year (8 is 1998)

2 digit

Representing the last 2 digits of the expiry year if the options trade beyond 10 years (11 is 2011).

Instruments, particularly derivatives, can have different trading sessions. There are 2 methods supported in the PGE symbology:

Multiple trading sessions which run either sequential or in parallel. Such instruments have a separate symbol for each trading session and also a combined symbol which consolidates information from the different sessions. The symbol for each session have a / appended to the instrument symbol, along with the session identifier, as follows:

[instrument symbol]MY/[session id].[exchange id]

The consolidated symbol does not have the / or the session id.

Separate trading mechanisms within a single session. Such instruments have a single instrument with separate fields for the different items of information for the different sessions. This is how LIFFE options are supported.

3. For Options, different month codes (indicated in the syntax by �M�) are used for different option types, as follows:

For Equity and Index options, the month codes are:

For Commodity and Futures options, the month codes are:

The Year code (indicated in the syntax by �Y�) denotes the expiry year. This can be either:

1 digit

Representing the last digit of the expiry year (8 is 1998)

2 digit

Representing the last 2 digits of the expiry year if the options trade beyond 10 years (11 is 2011)

The strike price for options is indicated in the symbology as nnnnn. This is the full strike price, including any decimal points and can be any number of characters.  If the strike price is quoted in fractional units, one of the following letters is used between the integer part and the fractional part (the numerator of the fraction) of the price:

H = halves, Q = quarters; E = eighths; W = twelfths; S = sixteenths;

T = 32nds; F = 64ths; O = 128ths; A = 256ths.

4. If the base currency (or, in the case of Sterling, the main currency) is the US Dollar, this is omitted, but the delimiter is still used.

5. Time code can be one of:

6. Non-exchange traded and contributed (for example GOVPX) bonds are defined as [bond code].CTR where �CTR� indicates that the bond data has been contributed.

7. The default chain qualifier is /C for constituents, this can therefore be omitted as shown in the example.

8. Grouping� is currently an index symbol. This can be omitted to get the chain for the complete exchange.

�Movement type� can be one of the following:

TVOL

Top movers by volume

GAIN

Biggest movers by % gain

LOSS

biggest movers by % loss

Valid country codes are the Datastream country codes as contained in the field DS country code (DZ).

Requesting News from GlobalTOPIC

The HEADLINE record is used to access whatever news sources are configured (the configuration setting looks like this):

	Tosca.GlobalTopicHdlr.MagList:DJA RNS ICV ICB ICE ADE AFS AFU AFX ANL

From a headline record, the underlying story can be accessed by requesting the instrument named in the "NEWS_STORY" record.
