How to verify your own broker's datacenter
Not every broker publishes their datacenter location. Here is how to identify it yourself:
- Find the server hostname in MT4/MT5. Go to Tools → Options → Server tab. The hostname (e.g.
live.icmarkets.comorny4-mt4.pepperstone.com) is your broker's server address. The datacenter code is often embedded directly. - Run a traceroute to the hostname. Open Command Prompt (Windows) or Terminal (macOS/Linux) and run
tracert hostname(Windows) ortraceroute hostname(macOS/Linux). The final hops will include datacenter infrastructure names — Equinix, Internap, or Zayo references are common. Look for location codes in the reverse DNS of the last few hops. - Geolocate the IP. Note the IP address of the destination (last hop in traceroute) and look it up at a BGP/IP geolocation service. Most will resolve to the correct city and ASN.
- Ask your broker's support directly. Most trading support teams will tell you which Equinix facility they use if you ask. The language to use: "Which Equinix datacenter does your MT4 matching engine run in?"
Once you know the datacenter, select the matching TradersProxy node in your account settings. The proxy node near your broker's DC is the one that minimises the final hop latency.
Why the datacenter matters more than the country
Two brokers "in the US" might be 80 ms apart from each other if one uses a Chicago datacenter and the other uses Equinix NY4. "US" is too broad a category for latency purposes. What matters is which specific facility — ideally which physical cage — your broker's matching engine sits in.
This is why broker-specific latency optimisation always starts with this question: which datacenter? Not which country, not which city. The specific Equinix (or Interxion, or Coresite) facility is the variable that determines whether a proxy node placed nearby will meaningfully reduce your fill latency.
