The OnlyForex engine runs around the clock and profits from speed differences — which makes it sensitive to latency. Where to rent a server, how the app finds your broker's servers on its own, and why paying long-term is a mistake.
A home computer is not fit for arbitrage, and ping is only part of the problem: reboots, dropped internet, Windows updates mid-session — each of these little things eats the very edge this whole setup is built on. The industry-standard answer is a rented Windows server (VPS) that sits in a data center close to your broker's servers and never shuts down.
This is the key difference between arbitrage and regular trading. The program lives between two points, and the path to each must be short: it receives the fast price stream from the OnlyProfit quote node — our nodes run in London, New York and Tokyo — and exchanges orders with your broker's server. The broker only ever talks to your VPS: nothing from it reaches the quote node. The ideal placement is a VPS sitting in the middle of this path — a stone's throw from both the quote node and the broker's server. Best case: all three points in one financial hub.
But if the VPS sits next to the broker yet an ocean away from the quote node (or vice versa) — the edge melts on transatlantic ping, no matter how fast everything else is.
The most common beginner mistake is buying a VPS before the broker is even chosen. The location is picked for two points at once: the specific broker's server and the nearest quote node. The right order:
The one you want to test. You'll get an email with credentials — including the server name.
The Connections section shows all of the broker's servers, the country and the ping to each — details below.
Short-term or hourly.
Both latencies fine — you're ready to launch.
This is usually where the guessing starts: traders beg broker support for addresses or dig through forums. In OnlyForex it's built in — the Connections section.
In Connections hit “+” and pick the account type: MetaTrader 4 or MetaTrader 5 — whichever your broker issued.
Into the Broker filter field — the exact name from the broker's email, e.g. Broker-MT5 Live 3 — and hit Scan.
Name, address, hosting country — and a live ping to each, measured right from your machine. The “Ping ↑” checkbox sorts fastest first.
Its address lands in the Server field. Now match it up: where this server is — and where the nearest quote node is (London, New York, Tokyo). Rent the VPS in that same spot.
The whole chain comes together in one place. No guessing, no blind buying.
The engine doesn't need expensive hardware — it needs stability and the right geography. Paying for 8 cores makes no sense: any money above this table is better left in the deposit.
Do the final measurement from the VPS itself, not from your home computer — what matters are the “server → broker” and “server → quote node” paths; your home channel plays no part in them. Connect to the VPS over RDP, install the app and paste the MT server name into the Broker filter in Connections — the ping is then measured from that machine. Torn between locations? Compare 2–3 options on an hourly cloud: it costs pennies and kills the guesswork.
Or you're ready to install it yourself.
No point paying months ahead — the next account will get a new server with a new IP anyway.
To get to know the app — yes. For live work — no: it's a voluntary 50–100 ms head start handed to the broker, plus the risk of a dropped connection mid-trade.
Both work (64-bit). Server editions are steadier for 24/7 operation, but Windows 10/11 is perfectly fine too.
Same principle, but take more headroom — from 4 CPU / 8 GB: browser profiles love resources. Details are in the OnlyBinary guide.
The full path — from renting a server to the first trade — is laid out in the guide: the chapters “What you need to start” and “From payment to launch” are open even before purchase. It's all done on your own in one evening, and if anything is left unclear — support is online 24/7.
