What residential ISP routing actually looks like
When you submit an order from home, it travels from your router to your ISP's local exchange, then into their transit network, then across one or more peering points to the network carrying your broker's data centre. Each of those hops introduces potential variance. When your ISP segment is under load — evenings, weekends, session overlaps — some of those hops slow down and the variance increases.
Run a traceroute to your broker's MT server hostname and you will typically see 10-15 hops. Several of those hops are on shared infrastructure that your ISP does not prioritise for low-latency traffic. The result is a path that is efficient enough for streaming video and browsing but produces inconsistent timing for the persistent connections that trading platforms depend on.
Why speed tests don't show this problem
Speed tests measure bandwidth to a nearby test server. They tell you how much data per second you can move over a short burst. That is useful for knowing if your internet plan is working. It tells you nothing about the route quality to a specific server in London, Sydney, or New Jersey.
What you want to measure is the round-trip time to your broker's actual MT server hostname. Ping it for 60 seconds at three different times: quiet afternoon, London open, and London/New York overlap. Watch the min-max spread across those pings. A narrow spread means the route is stable. A wide spread means your ISP's transit is introducing jitter at the moments that matter most.
What a proxy actually changes
A proxy route does not speed up your ISP. What it does is replace the variable, multi-hop residential path with a direct, dedicated connection from a node that sits at or near your broker's data centre. Instead of your trading traffic taking whatever route your ISP's transit has chosen today, it takes a specific, uncongested path that was selected for exactly this purpose.
That is the priority route — not a VPN that routes all your traffic through a foreign server, not a VPS that moves your terminal to a remote machine. A routing layer specifically for your trading sessions that keeps the path clean regardless of what your residential ISP is doing at any moment.
