Copy One Account to Many: Multi-Account Trade Copying

Fan a single source account out to several followers at once — each sized to its own balance, pausable on its own, and able to sit at different brokers or platforms.

Copying one account to many is the same idea as copying between two accounts, fanned out: a single source drives several followers at once. You trade on the source, and every follower opens, modifies and closes alongside it — each sized to its own account. It's how you keep a set of accounts you own moving together without placing the same trade several times.

The fan-out model

A single repeater links one source to several followers at once. When the source opens a position, the copier dispatches a matching order to every follower on that repeater in parallel; when it closes, they all close. Adding a follower later just adds it to the repeater — the others keep running. If you're new to the source/follower idea, start with copying between two accounts.

Sizing matters more with many accounts

When followers are different sizes, copying one lot onto all of them would over-expose the small ones and under-use the large ones. This is where equity-ratio sizing earns its keep: one rule scales each follower by its own balance, so a $2,000 account and a $50,000 account both take a proportionate slice of the same source trade. A fixed multiplier instead applies the same multiple everywhere. The mechanics are in position sizing when copying trades.

What adapts per follower — and what doesn't

One repeater applies a single configuration to all its followers: the sizing mode, multiplier, symbol allowlist and any symbol remaps are set on the repeater, not per account. Two things still adapt to each follower on their own:

• Pause is per-follower — take one account out of copying for maintenance while the rest keep running off the same source.
• Equity-ratio sizing scales each follower by its own balance from that one rule, so different-sized accounts already take proportionate trades with no per-account setting.

When you need genuinely different rules for different accounts — a different multiplier, or a different symbol filter — configure a separate repeater from the same source to that follower, set up its own way. A single source can have more than one repeater, each configured differently.

Mixed brokers and platforms

Followers can sit at different brokers, and on either MetaTrader 4 or 5. The order action copies the same across all of them; where a broker names an instrument differently, a symbol remap on the repeater translates it. Because the remap is set on the repeater, followers that need different name mappings each get their own repeater. Copying across MT4 and MT5 works in either direction — see MT4 vs MT5 for copying.

What to expect across many fills

With several followers, each one's broker fills at its own available price, so the fills won't be identical to the source or to each other — a normal, expected spread covered in why follower fills differ. A good copier flags any order that didn't copy, with a reason, rather than failing silently.

Where Trepeat fits

Trepeat copies one MetaTrader source to as many followers as your plan allows, in the cloud and in real time. A repeater applies one sizing rule and symbol allowlist to its followers — equity-ratio scales each by its own balance, and individual followers are pausable; when you want different rules per account, configure more than one repeater from the same source.
