What trading VPS providers are actually selling you
Trading VPS marketing focuses on uptime guarantees (99.99%), dedicated resources (not shared), MT4-optimised images, and low ping to their own internal network. What they do not sell, because they cannot guarantee it, is your ping to your specific broker's matching engine. A VPS with 99.99% uptime in a datacenter with poor peering to LD4 is useless for a London-broker scalper.
VPS providers know this and do not publish it. They advertise CPU cores and RAM because those are easy to measure and compare. They do not advertise RTT to Equinix LD4 because it varies dramatically based on the provider's peering agreements — and many providers have poor peering.
The specification that actually matters: time-to-fill
Time-to-fill (TTF) is the gap between when MT4 sends an order and when the broker confirms the fill. It is almost entirely determined by the round-trip latency between your VPS and the broker's datacenter. You can have 64GB RAM and a 10-core CPU; if your RTT to the broker is 300ms, your TTF is 300ms.
This is the critical disconnect. VPS providers market specs that do not affect TTF. They do not market the spec that does: network path quality.
Why 'London VPS' doesn't mean 'low latency to LD4'
LD4 is an Equinix facility in Slough, on the western edge of Greater London. Many VPS providers with "London" in their name are actually in Docklands, Telecity, or other London-area datacenters. The peering relationship between those facilities and Equinix LD4 varies significantly. Some have direct, low-latency connections (2–3ms). Others route through Frankfurt and back, adding 50–100ms of latency.
The only way to know is to test it yourself. A VPS advertised as "London" with 8 cores and 16GB RAM might have worse latency to LD4 than a cheap Vultr instance if the peering is poor.
How to measure your actual execution latency from your VPS
SSH into your VPS. Find your broker's server hostname under MT4 Tools > Options > Server tab, then run: ping YOUR_BROKER_HOSTNAME.com. Run tracert YOUR_BROKER_HOSTNAME.com to see the hops your traffic takes. Look at two things: the number of hops and the RTT at the final hop.
If you are on a "trading VPS" that claims to be near your broker's DC and your final hop RTT is over 10ms, your host has poor peering. If your tracert output shows hops crossing continents (e.g., Frankfurt, Amsterdam, Paris) before reaching the broker, you are routing inefficiently. For a detailed breakdown of what these metrics mean, see the high-ping troubleshooting guide.
The smarter approach: a proxy node at the broker's DC
Instead of hoping your $60/month VPS host has good peering to LD4 or NY4, use a TradersProxy node that is positioned inside or adjacent to those facilities. Your MT4 on the VPS routes SOCKS5 through TradersProxy; the proxy connects directly to the broker. The broker latency is now independent of your VPS host's network quality.
This means a cheap $10/month cloud VPS running MT4 with TradersProxy SOCKS5 can deliver better execution than a premium $60/month trading VPS without a proxy — if the proxy node is well-positioned. You save money and get better execution.
