R4CopierPassing evaluations is the hard part. Running six accounts across four firms afterwards is the part nobody warns you about — different platforms, different sizes, different rulebooks. R4Copier mirrors your master into all of them, with a sizing rule per account.
The strategy that passed the evaluation still works. Executing it eight times, correctly, at the same moment, is what breaks.
A trader with one funded account has a trading job. A trader with a $25K evaluation at one firm, a $100K funded account at a second, two scaled accounts at a third and a fresh challenge at a fourth has a logistics job — and it is the logistics that end up costing the account.
The failures are boringly consistent. You size a slave off the master’s lot instead of its own equity and put 4% of risk on a $25K account. You enter the master, get distracted, and three accounts never receive the trade. You close six positions manually and miss one. None of these are strategy failures. Every one of them shows up as a rule breach.
A copier removes the manual step. What it does not remove is the need to know which of your accounts is allowed to hold that trade — which is the part of this page worth reading twice.
Set per slave, not globally. Accounts of different sizes should not receive the same volume.
Each slave scales to its own balance. A $200K account takes four times the volume of a $50K account from the same master signal, automatically.
This is the default worth starting from when your accounts differ in size, which for most funded traders is always.
The slave takes a fixed proportion of whatever the master traded — 50%, 200%, whatever you set — regardless of balance.
Right when your accounts are already proportional, or when you deliberately want a slave to run hotter or cooler than the master.
The slave always trades the same lot size no matter what the master does. Predictable, and immune to a fat-fingered master entry.
Useful for an account near a drawdown limit, or one you are deliberately keeping small while you rebuild it.
Symbol names differ between firms, and that breaks copiers. The same pair may be EURUSD at one firm, EURUSD.r at the next and fxEURUSD at a third. R4Copier maps prefixes and suffixes per connection, so a master fill on one naming scheme lands correctly on all of them.
This is the section most vendors skip, and it is the one that decides whether copying helps you or costs you an account.
R4Copier faithfully reproduces what your master does. That is the feature, and it is also the risk: if a trade is fine on the account you are trading and forbidden on the account receiving it, faithful reproduction is a breach. Firms differ on all of the following, and none of it is visible to a copier:
Group your slaves by rule set rather than by firm. Trade the master as though it were the strictest account in the group, because in effect it is. Toggle copying off per slave when a trade would not be permitted there — R4Copier keeps that account’s rules and history for when you switch it back on. And re-read each firm’s terms after every payout or scaling event; they get revised more often than traders expect.
Scope, stated plainly: this page is about copying between accounts you personally own. Copying into accounts belonging to other people is a different activity, most firms prohibit it, and R4Copier is not sold or positioned for it.
Nothing here is legal advice or a compliance guarantee. Your firm’s written terms are the authority, and staying inside them is your responsibility.
A funded account represents an evaluation fee you paid and a challenge you passed. Its login is usually the only thing between an attacker and a breach of your firm’s rules — and firms generally treat account access as the trader’s responsibility, not the vendor’s.
Cloud copiers require that login by design: their servers place the orders, so their servers must be able to authenticate. R4Copier runs on your machine or VPS, so the credential stays in your operating system’s keystore and never reaches us. There is no vendor-side database of funded-account logins to breach, because we never receive one.
The reasoning is set out in full on trade copier without password sharing, and the architecture behind it on self-hosted trade copier.
Copying only happens while the terminal is running. For accounts carrying a firm’s capital that is an argument for treating the host as infrastructure: a low-cost VPS in the region closest to your firms’ servers, running headless, watched from the web dashboard on your phone.
It also shortens the execution path — median master-to-slave latency is 42–60ms on a co-located VPS against 80–150ms on a home connection. What that does and does not buy you is covered on local trade copier.
Most firms permit copying between accounts you personally own, and many say so explicitly in their FAQ. What they consistently prohibit is copying between accounts belonging to different people, or running a signal service into other traders’ funded accounts.
The rules are per firm and they change. Read the terms of each firm you trade with rather than relying on a general answer from a software vendor — including this one.
Percentage of equity is usually the right rule when accounts differ in size, because each slave scales to its own balance instead of inheriting the master’s absolute volume.
Percentage of lot suits accounts that are already proportional to each other, and a static volume suits a slave you want capped regardless of what the master does. R4Copier sets the rule per slave, so a $25K evaluation and a $200K funded account can follow one master without either being mis-sized.
The copier will place the order; it does not know your firm’s rulebook. If one account forbids holding through a news release or over the weekend and another does not, copying blindly is how you breach the stricter one.
Group accounts by rule set rather than by firm, keep the strictest account’s constraints in mind when you trade the master, and toggle copying off per slave when a trade would not be allowed there.
It can. Several firms score consistency — the share of profit from your best day or best trade — and a copier faithfully reproducing one outsized winner across every account reproduces that skew everywhere at once.
This is a strategy question rather than a software one, but it is the failure we hear about most from traders running multiple funded accounts.
Any firm that gives you a MetaTrader 4, MetaTrader 5 or cTrader login — which is nearly all of them. FTMO, FundedNext, The5%ers, CTI, Fintokei, TTP and AudaCity all fall into that category.
Because the terminal connects through the platform rather than through a firm-specific integration, there is no waiting for us to add support for the firm you just passed.
That depends entirely on where the copier runs. A cloud copier has to store a working login for every account it trades, which puts your funded accounts in a third party’s database.
R4Copier runs on your own machine and keeps credentials in your operating system’s keystore, so there is no vendor-side copy to breach. The full reasoning is on the trade copier without password sharing page.
