What happens to your connection during a news release
When an NFP print or CPI number drops, two things happen simultaneously on the network side. Your broker's matching engine sees a surge in orders — every automated system, every EA, every manual trader who was positioned and waiting hits the same server within milliseconds. At the same time, the ISP transit networks carrying that traffic also spike in load. Your residential connection is sharing that transit with everyone else on your ISP segment who is also doing something with their internet connection at that moment.
The result is that jitter — the variation in your round-trip time — spikes exactly when you need stability. An order that normally arrives in 45ms might arrive in 190ms. The price has already moved. The spread has already widened. Your fill is at a level that no longer matches your intent.
What you can and cannot control at news time
You cannot change the broker's server load. You cannot change how many other traders are submitting orders at the same millisecond. What you can control is the quality of your path from your machine to the broker's matching engine.
A dedicated proxy route does not share its transit capacity with residential traffic. The path to the broker's data centre is uncongested from the node outward. The jitter that residential ISPs add under load is not present on a dedicated routing layer. That is not magic — it does not make the broker process your order faster. It makes your order arrive at a consistent time rather than a variable one, which is how you trade the news release on the same terms as your competition's infrastructure.
