R4CopierTrading infrastructure that never asks for your keys.
We’re Rhino4 Solutions — the team behind R4Copier, the self-hosted forex trade copier built for traders who run several accounts and refuse to hand their passwords to a third party.
A trader’s tool — by traders who got tired of fragile copiers.
R4Copier started at a prop trader’s desk, not in a boardroom. Every copier on the market wanted broker passwords on someone else’s server — an unacceptable trade for anyone running five-figure funded accounts.
So we built the copier we wanted to use: one that runs entirely on your own machine or VPS, keeps your credentials encrypted in your OS keystore, and connects to your brokers through a trade-only bridge that can never move your money.
Today, Rhino4 Solutions ships that engine to traders, signal sellers, and desks across MT4, MT5 and cTrader — with sub-50ms replication and prop-firm guard rails built in. The principle hasn’t changed: your accounts, your machine, your control.
Every copier I tried wanted my broker passwords on their server. I’m not putting a five-figure prop account behind someone else’s login session. So we built one that runs on your own machine — your VPS, your hardware, your keys.
Four principles we won’t compromise on.
Your keys stay yours
Broker credentials are encrypted locally in your OS keystore and never reach our servers. Privacy isn’t a setting — it’s the architecture.
We can’t move your money
Each broker connection uses a trade-only token. R4 cannot withdraw, transfer, or alter funds — not even with a compromised licence.
Speed is a feature
Sub-50ms master-to-slave replication, measured per slave in the Trade Monitor. If you can see the latency, you can trust it.
Honest about the tool
R4 is software, not signals or advice. We tell you plainly what it is — and what it isn’t — so you buy it for the right reasons.
