Company

BIDS Trading, L.P. is a registered broker-dealer and the operator of the BIDS Alternative Trading System (ATS), which was designed to bring counterparties together to anonymously trade large blocks of shares. Developed by a consortium of leading financial services firms, the BIDS ATS resolves the classic paradox of the block trader – the need to find legitimate trading counterparties without prematurely revealing trading intentions.

The BIDS ATS is open to all qualifying broker-dealers and their institutional clients, subject to basic credit and regulatory requirements.
