The participants, how each is paid, how they connect, and where their incentives collide.
Read the map left to right along the path of an order: investors, the brokers and banks that take their orders, the firms that supply the other side, the venues where it happens, and the plumbing that guarantees and settles it. Oversight runs along the top; the data and infrastructure everyone depends on runs along the bottom. Click or tap any node for its dossier. On a computer, hover to see what it connects to. The accent-colored flag on a node means a conflict of interest lives inside it, written up with the case each side makes.
Every record here says whether it was verified against a primary source, is secondary (backed only by a reputable secondary source), or is hand-curated from reference knowledge and still to be checked. Figures are few on purpose; where a number would be a guess, it says NOT AVAILABLE and why.
Every participant, by lane. The list is the keyboard and small-screen route into the same dossiers.
