What are the best electronic trading platforms for high-volume order routing on an institutional trading desk?

For an institutional desk doing high-volume order routing, the “best” platform depends on your asset class, venues, latency needs, OMS/EMS stack, and how much customization you want. In practice, desks often use a combination of EMS/OMS + FIX connectivity + smart order routing (SOR) + direct market access.

Here are the most widely used and respected options, grouped by use case:

1) Institutional EMS / multi-asset execution
