A copy group is how you tell Tradecopia which accounts to link for trade replication: one leader account that you trade manually, and one or more follower accounts that mirror those trades automatically.

You might need this article if:

A copy group defines exactly which accounts are linked for replication. Every group has one leader account, the account you trade manually through your broker platform, and one or more follower accounts that automatically receive copies of each trade.

Tradecopia only replicates between accounts that are explicitly assigned to the same group. Having active broker connections in Tradecopia does not automatically link accounts for replication. A group must be configured.

Quantity multiplier controls how many contracts the follower trades relative to the leader. Both whole numbers and decimal values are supported.

Decimal multipliers round up when the result is a fractional contract. For example, a 0.5× multiplier on a leader trading 1 contract produces 1 follower contract (not 0.5). A 0.5× multiplier on a leader trading 3 contracts produces 2 follower contracts.

For full multiplier documentation, including how decimals interact with prop firm contract limits and contract mode options, see How quantity multipliers work on follower accounts.

Copy type controls which contract the follower trades. This matters when the leader and follower are set up for different contract sizes of the same instrument.

Set the copy type to Standard unless you specifically need the follower to trade a different contract size than the leader.

You do not need to recreate a group to change which accounts are in it:

If an account you expect is not listed when you create or edit a group, it is usually one of these:

Enable the group to start replication. Disable it to pause replication without deleting the group configuration.

Each follower within the group also has its own individual enable/disable toggle. You can stop replication to a specific follower while the group remains active and copying to others.

To trade through a group: enable the group, then place your trades on the leader account through your broker platform as normal. Tradecopia detects the leader trades and sends matching instructions to each enabled follower.

If a follower stops receiving trades unexpectedly, check whether the Position Reconciler has automatically halted that follower due to a position mismatch. This is separate from the manual enable/disable toggle. See How the Position Reconciler protects your follower accounts.

There is no limit to the number of groups you can create. Each group operates independently. Changes to one group do not affect any other.

You might run multiple groups to:

Multiple groups can be active and replicating at the same time. Only one leader account can execute trades per group, but you can have several groups running in parallel with different leaders.

Replication is group-scoped, not connection-scoped. This is a common source of confusion.

When you connect broker accounts in Tradecopia, those accounts are not automatically linked to each other. They are linked only when you assign them to the same copy group. A Tradovate connection showing Connected and a Rithmic connection showing Connected do not replicate to each other unless both are in the same group.

Whether those accounts can belong to different people depends on the account type. See Can I copy between accounts owned by different people? below.

If trades appear to copy within one connection but not across connections, the most likely cause is that no copy group has been configured to span those accounts. Adding connections does not create a group: the group must be set up manually.

Tradecopia fully supports multiple groups running in parallel, with each group replicating independently at the same time.

Example setup:

As long as each group has its own dedicated leader account, there is no restriction on how many groups run in parallel.

Before trading across multiple prop firms: confirm that each firm permits copy trading and third-party platforms on your account type. See Is my prop firm compatible with Tradecopia?.

Whether you can copy to an account that belongs to someone else depends on the type of account.

Personal accounts (funded with your own money): Yes. You can connect and copy between personal accounts that belong to different people, even on the same broker. For example, you can copy from your own Tradovate account to your spouse's personal Tradovate account. Having a separate set of login credentials for that account is fine.

Prop firm accounts: No. A prop firm account must be under your own name and profile. You cannot connect a prop firm account that belongs to a different person, such as your spouse's prop firm account, even if it is with the same broker. Prop firms allow only one profile per person and prohibit copy trading across accounts owned by different people. This is measured per individual, not per household. Because it is enforced when you add the connection, the account cannot be connected in the first place, so it never becomes available to add to a group.

Three rules apply to all copy groups without exception:

Note: An account that is currently under Hard Lock cannot be added to a copy group. If you need to add a locked account to a group, wait for the lock to expire.
