This is a great question, and the full answer involves lots of mechanism design nuance. The short answer is that we have uniform clears per trading instrument, and bids are sealed, so there's no direct signaling game that would allow someone to try to pass off an alpha trade as a hedge. We plan to introduce a mechanism that will enable signaling through tokens (opaque identifiers). Bidders can attach whatever token they want, and other bidders can price discriminate against tokens (change their prices for, refuse to trade with, trade exclusively with) based on historical post-trade outcomes that we make known via an immutable audit trail. Participants can create and use tokens freely, so it's not segmentation. Instead, it's a means of inducing a repeated play game and a market for reputation.
