This tag must always be the last field in a message (i.e. it serves, with the trailing <SOH>, as the end-of-message delimiter).

Message Notes

The Security Definition (d) message is used to send information about an exchange-listed instrument. TT FIX sends zero or more of these messages to a FIX client in response to a Security Definition Request (c). A security definition contains all standing data at the markets that matches the filter criteria sent in the Security Definition Request (c). After TT FIX delivers standing data to the FIX client, TT FIX sends unsolicited updates to that list of standing data (for instance, if a market lists a new product at midday).

Determining tick sizes and tick values

To determine the tick size and tick value of a given contract, the FIX client must:

  • In the Security Definition Request (c) message, set Tag 17000 (RequestTickTable) = Y.
  • With the resulting Security Definition (d) message, calculate the values using the following algorithm.
    if tag 16456 (NumTickTblEntries) == 0
    {
      (The tick size (and tick value) are the same for all prices.)
      Tick Size (for all prices) = Tag 16552 (ExchTickSize)
      Tick Value (for all prices) = Tag 16552 (ExchTickSize) * Tag 16554 (ExchPointValue)
    }
    else
    {
      (The tick size and tick value vary by price level.)
      Base Tick Size = Tag 16552 (ExchTickSize)
      P = price in Points (decimal) for which the tick size is required
      for (int i = 0; i < Tag 16456 (NumTickTblEntries); i++)
      {
        if ( P < (Tag 16458 (MaxPrice) for row i) )
        {
          Tick Size (for price P) = Base Tick Size * (Tag 16457 (NumTicks) for row i)
          Tick Value (for price P) = Tick Size (for price P) * Tag 16554 (ExchPointValue)
          exit loop
        }
      }
    }
    

Working with spreads and strategies

When a FIX client requests a security definition for a spread or strategy, TT FIX responds by sending:

  • A Security Definition (d) for the spread itself. A leg repeating group exists for each leg of the spread. Tag 555 (NoLegs) is set to the total number of leg repeating groups (spread legs) associated with the spread.
  • One Security Definition (d) for each leg of the spread.
