Copiers

The link between a leader account and a follower account.

A copier is one directed link: parent → follower. The parent is the leader account whose trades are the source. The follower receives copies.

The Copiers list with parent, follower, mode, risk and status columns; mode is an inline dropdown on each row
Each row is one parent-to-follower link. Mode is a dropdown on the row, so switching one follower to paused takes a single click.

The Risk column shows the sizing at a glance — Bal. Ratio 1.0000, Eq. Ratio 1.0000, Lot × 0.2500, Fixed 0.2500 — which is the fastest way to spot a follower configured differently from its siblings.

This is the thing to internalise, because everything else follows from it.

Risk sizing, mode, lot caps, stop-loss handling — none of it lives on an account. It all lives on the copier. Which means:

  • One leader can drive twenty followers at twenty different sizes.
  • Pausing one follower does not touch the other nineteen.
  • The same account can be a follower of one leader and the parent of another.

What happens when the parent trades

  1. The trade is detected

    Trademetry sees the position open on the parent account.

  2. Each copier is evaluated separately

    Every copier whose parent is that account gets its own pass.

  3. Filters run

    Is the copier enabled, is it in active mode, is this symbol allowed, is the follower under its open-trade limit, is the signal fresh? Any failure stops this copier — and only this copier — with a recorded reason. See Filters and limits.

  4. The size is calculated

    From the copier's risk type, then rounded down to the broker's lot step and capped by Max Lot. See Risk types.

  5. The order is placed

    On the follower, with stop-loss and take-profit handled as the copier says.

Closes follow the same path: when the parent position closes, the corresponding follower positions are closed.

Copy events

Every one of those passes is recorded as a copy event, whether it resulted in a trade or not. Open a copier and its event list shows what happened and, for anything skipped, why — symbol_disabled, max_open_trades_reached, copier_not_active, outside_trading_hours, and so on.

"The copy did not happen" is nearly always answerable from the copier's event list without asking anyone. A skip is recorded with its reason; a failure is recorded with the broker's error. Silence there means the parent trade never arrived, which is an account problem rather than a copier one.
