Initial Configuration

Setting System Clock

Set the date, time and time zone on the BVMF Gateway:

  • Date should be set to the correct date.
  • Time should be set to BRT (Brazil Time) on the machine that hosts the BVMF Gateway, and the AM/PM setting should be verified.
  • Time Zone offset should be set to Coordinated Universal Time (UTC-3) with Daylight Savings enabled. BRT is three hours behind the Coordinated Universal Time (UTC).

Setting Daylight Savings Time

You must enable the “Automatically adjust clock for daylight saving changes” setting on the server-class machine hosting the gateway. Time zones moving to the summer BRST (Brasilia Summer Time) are two hours behind the Coordinated Universal Time (UTC-2). Otherwise, BRT is three hours behind UTC. Daylight Savings Time generally occurs in October in Brazil locations that adhere to the BRST time zone change.

Standard time (UTC - 3 hours) runs from February to October while Daylight/Summer time runs from October to February (UTC - 2 hours). The exception is when Carnaval falls on the third Sunday of February, then DST will be extended one week.

TT will issue a Customer Advisory if BVMF modifies their schedule based on Daylight Savings time.

Changing Gateway Time and Time Zone

Due to the default settings in its configuration files, TT recommends that you set the TT Gateway to run in the BRT time zone (Brazil time) with Daylight Savings enabled.

If you decide to run the BVMF Gateway in another time zone, you must:

  • Run the BVMF Gateway in the other time zone with the daylight savings setting enabled for that time zone.
  • Adjust the times in ttchron.ini to match the time in which the BVMF Gateway runs.

Example

Trading Firm ABC based in Sao Palo decides to run the BVMF Gateway in the Sao Palo time zone. ABC sets the system clock to Sao Palo time, which is BRT, and turns off daylight savings. Whenever Daylight Savings changes, ABC edits ttchron.ini to account for new time schedules.

TT Direct Trader IDs

TT Direct Trader IDs on BVMF Gateways use the Member-Group-Trader (MGT) format MemberIdxxxyyy, where:

  • MemberId is provided by the brokerage firm.
  • xxx is the group ID provided by the firm.
  • yyy is the exchange-provided Desk Trader ID or firm-provided DMA Trader ID.

BVMF assigns Desk Trader IDs to the brokerage firm. The firm then assigns multi-character IDs to all DMA Traders associated with the firm. All resident and non-resident traders must establish a relationship with a brokerage firm in order to trade in the BVMF markets.

Firms can define their own Member ID or Group ID, however, they must use the three-character Desk Trader ID provided by BVMF.

Example TT Direct Trader ID (MGT) for connecting to a BVMF Gateway

M (Member ID): DEF456

G (Group ID): TSE

T (Desk Trader ID): ALZ

TTORD Trader IDs

TTORD Trader IDs on BVMF Gateways use the Member-Group-Trader (MGT) format TTORDxxxyyy, where:

  • TTORD is hard-coded in the gateway to identify a proxy traders.
  • xxx is the group ID provided by the firm.
  • yyy is the exchange-provided Desk Trader ID or firm-provided DMA Trader ID.

The following list describes TTORD trader IDs on the gateway.

  • BVMF Gateways supports TTORDs.
  • You can map multiple TTORDs to one direct exchange trader.
Note

Each TTORD ID that connects to and trades on the Exchange must use a unique clearing account.

You must complete the following fields in TT User Setup to map a TTORD proxy trader to a direct trader:

  • Exchange: The TT Gateway exchange-flavor (e.g., BVMF-A).
  • Member: An up to 7-character value defined by the firm
  • Group: A three-character value defined by the firm.
  • Trader: A three-character variable defined by BVMF and assigned to a Desk Trader, or a multi-character value (i.e., up to 11 characters in TT User Setup or Guardian) defined by the firm and assigned to a DMA Trader.
