What is the size of a block? Is there a minimum volume requirement?

The size of a block (or minimum size requirement) is defined by each trader, on an order-by-order basis.

The minimum size requirement provides the most basic level of protection in the BIDS ATS. Since each trader determines the size of a block, no counterparty with a size less than the specified minimum receives any information about their order.

What is a BIDS Scorecard℠?

To give traders more control over their trades, the BIDS ATS maintains a scorecard for each trader by tracking trading behavior in different areas. While traders never see their counterparty’s scores, they can then filter out users with certain behaviors. Although a trader’s scorecard is never revealed to other users, traders can apply a BIDS Filter℠ to their order, to filter out traders whose trading behavior does not meet their requirements. Traders can customize three different filter templates (Normal, Conservative, and Aggressive).
