Algo execution needs modular APIs
What happened
Peers’ push to host multiple dealer algos has shifted expectations toward plug‑and‑play execution stacks that minimize integration friction and enable real‑time benchmarking. Engineering teams are being asked to expose modular APIs and standard telemetry so new dealer algos can be onboarded without risky, custom point integrations. (financefeeds.com)
Why it matters
