# Pause if any open trade has these magic IDs

This option makes the EA **pause itself** if it detects any open trade on the account with specific **Magic IDs**.

{% hint style="info" %}

#### How it works

* Enter a comma-separated list of magic numbers\
  Example: `111111,222222`
* If any open trade matches one of those Magic IDs, this instance will:
  * pause
  * not open new trades
    {% endhint %}

{% hint style="info" %}

#### What it’s for

This is used to coordinate trading between:

* multiple SmartChoise instances
* SmartChoise and other EAs
* separate strategies that shouldn’t trade at the same time
  {% endhint %}

{% hint style="info" %}

#### On-screen message

When active, the panel will display:\
\&#xNAN;**“Trading paused – Multi-instance coordination”**
{% endhint %}

{% hint style="info" %}

#### Important note

If the **Master SmartChoise chain** is currently trading, the full chain is still allowed for linked Master/Child instances (so you don’t accidentally block your own active chain).
{% endhint %}
