Market Makers can place a maximum of 30 orders on a single side of the order book.

There are several execution options for Takers:

• For Firm execution only:

  qsEnabled should be = false . firmBookEnabled = true must be set.

• For QS execution with a specific LP:

  Set qsEnabled = true and specify makers = [LP's ID] . firmBookEnabled should be = false

• For automatic selection of the most competitive QS LPs by FM:

  Set qsEnabled = true and specify makers = [Array of LPs' IDs] . firmBookEnabled should be = false

• For automatic selection of the best price between all available QS and aggregated Firm:

  Set both qsEnabled = true and firmBookEnabled = true
