# Troubleshooting copiers

Work out why a trade didn't copy and how to fix it — disconnections, paused copiers, protection triggers, symbol mappings, slippage, and order-type rules.

When a trade doesn't appear on a receiver, the cause is almost always recorded in the [copier logs](/copy-trading/copier-logs.md). Start there, then match what you see to the cases below.

## A trade didn't copy

| What you see                                                             | Likely cause                                                                                                                                  | Fix                                                                                                                  |
| ------------------------------------------------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------- |
| **Copier Action** showing the copier paused, or a disabled status toggle | The copier is paused, or missing a sender/receiver.                                                                                           | Confirm a sender and at least one receiver are set, then switch the copier to **Active**.                            |
| **Connection Issue**, red account indicator                              | The sender or receiver is disconnected.                                                                                                       | Use **Resolve** on the account row to reconnect on the [Accounts](/connecting-accounts/connecting-accounts.md) page. |
| **Copy Failed** referencing a symbol                                     | The symbol isn't mapped on that receiver, or the broker doesn't offer it.                                                                     | Check [Symbol mapping](/copy-trading/symbol-mapping.md); set or correct the receiver's symbol.                       |
| Nothing logged for that symbol                                           | The symbol is **disabled** in symbol mapping.                                                                                                 | Re-enable it in the mapping table's **Status** column.                                                               |
| **Copy Failed** mentioning slippage                                      | The receiver's price was worse than the sender's by more than **Max Slippage**.                                                               | Raise or clear Max Slippage in the receiver's advanced settings.                                                     |
| Pending orders never copy                                                | Trada copies open positions, not pending orders. The **Copy placed orders** and **Copy only market orders** options are marked *Coming soon*. | Nothing to change: when the sender's pending order fills, the new position is copied like any other trade.           |
| One side (buys or sells) never copies                                    | The receiver's **copy direction** is set to Buy Only or Sell Only.                                                                            | Set copy direction to **All (Both)** if you want both sides.                                                         |
| Trades stopped after a loss/profit level                                 | A **Protection Triggered** entry — a limit closed the copier's positions on that receiver, paused the whole copier, or both.                  | Review [Risk protection](/copy-trading/configure-receiver/risk-protection.md) thresholds for that receiver.          |
| Nothing copies at certain times                                          | **Working hours** restrict the copier to set windows.                                                                                         | Check or adjust [Working hours & scheduling](/copy-trading/working-hours.md).                                        |

## Sizing looks wrong on a receiver

* The receiver may be on a different [lot-sizing mode](/copy-trading/configure-receiver/lot-sizing-modes.md) than you expect — check the **Multiplier** column.
* **Max Lot Size** caps the result after sizing; a capped trade is smaller than the raw calculation.
* **Fixed % Risk** needs a stop-loss to size against — without one, the trade isn't copied (or is copied at the broker's minimum lot if **Force Minimum Lot Size** is on). See [Lot-sizing modes](/copy-trading/configure-receiver/lot-sizing-modes.md).

## Reverse Positions on a prop firm account

Leave **Reverse Positions** off on prop firm accounts: copying in the opposite direction conflicts with prop firm rules and terms of service. If a funded account is receiving reversed trades, open the receiver with **Edit** and switch Reverse Positions off.

## A position didn't close when I expected

Pausing or deleting a copier, and removing a sender or receiver, all leave **open trades open** — see [Copier states & lifecycle](/copy-trading/lifecycle.md). Trada has no button to close positions for you; close them on the trading platform itself.
