# One entry across all charts at the exact same time

If enabled, it ensures that only **one trade** is opened at a time across all charts, even if multiple setups occur simultaneously. 

If disabled multiple trades can be opened by different charts at the same time increasing risk and exposure.

{% hint style="info" %}
If several charts detect valid signals at the same time, **only one** will open a trade. The rest will wait for the next signal.
{% endhint %}

{% hint style="success" %}

#### **Use Case**

* Helps avoid **overexposure** when running multiple charts on the same account.
* Prevents **duplicate or overlapping trades** from being opened by several EA instances at once.
* Supports **simpler, more controlled portfolio management**.
  {% endhint %}

{% hint style="warning" %}
This does **not block future trades** entirely. If you want to limit the number of opened trades at the same time use [Max Open Trades account wide](/smartchoise-manual/options/account-protection/max-open-trades-across-account.md) option\
If market conditions change or a new setup appears, **the other charts will still be able to trade later** — just not simultaneously.

❌ This setting **does NOT block**:

* Manual trades.
* Trades from **other EAs**.
* Trades opened **at a different time by the EA**.

 It only coordinates trade entries **between SmartChoice EA charts** with this option **enabled**.

Charts will still monitor for entries individually and act when **a new signal occurs and no other SmartChoice trade is active**.
{% endhint %}

{% hint style="info" %}
Use this feature when you want **extra safety and synchronization** across multiple SmartChoice charts.\
It’s great for accounts where **only one trade at a time** is desired to reduce complexity, risk, or overlapping exposure — while still keeping future opportunities open.
{% endhint %}
