Order Types

BIDS supports a variety of order types, such as Limit Orders and Midpoint Pegged Orders, which may be submitted as Firm for immediate execution or Conditional for simultaneously searching liquidity across venues.

Sponsored Access

Allows buy-side users to settle trades and pay 100% of their valuable commission dollars to the sponsoring broker-dealer of their choice rather than disintermediate brokers, helping to maintain and enhance key broker-dealer relationships.
