# Create a copy-trading or MAM subscription

You can create a copy-trading or MAM subscription by subscribing an investment account to a master account in the Back Office.

In the case of copy trading and MAM, a single investment account may be subscribed to multiple master accounts, which means that investment accounts may have multiple subscriptions.

To create a subscription:

{% stepper %}
{% step %}
Go to **Investment Platform** and expand the required platform instance, such as MT4, MT5, or cTrader.
{% endstep %}

{% step %}
To create a copy-trading subscription, go to **B2COPY** > **Subscriptions**.\
To create a MAM subscription, go to **Mam** > **Subscriptions**.
{% endstep %}

{% step %}
On the **Subscriptions** page, click the **+Create** button located at the upper-right page corner.

{% endstep %}

{% step %}
On the **Create Subscription** page, enter a master account login and an investment account login to subscribe the investment account to the master account.
{% endstep %}

{% step %}
In the **Allocation method** dropdown, select a method used to calculate the size of positions that an investor copies from a master account. You can select one of the following methods:

* Proportional to Balance
* Proportional to Equity
* Proportional to Balance x Ratio
* Proportional to Equity x Ratio (default)
* Fixed Lot Allocation
* Ratio Multiplier

To learn more about each allocation method, refer to [Allocation methods for copy trading and MAM](/copy-trading-pamm-and-mam-concepts/allocation-methods-for-copy-trading-and-mam.md).
{% endstep %}

{% step %}
In the **Risk Ratio** field, enter a numeric value. The default value is 1. Use a dot "." as a decimal separator for numeric values.

A risk ratio is used to recalculate the size of positions that an investor copies from a master account. A risk ratio only applies to the allocation methods that use the risk ratio in their formulas.
{% endstep %}

{% step %}
In the **Copy Direction** dropdown, select one of the following options:

* **Normal** – This option doesn't change a trade side when positions are copied from a master account to an investment account. For example, if a master trader opens a *sell* position, this position is copied as a *sell* position for an investor.
* **Reverse** – This option changes a trade side when positions are copied from a master account to an investment account. For example, if a master trader opens a *sell* position, this position is copied as a *buy* position for an investor.
  {% endstep %}

{% step %}
Enable the **Send email** checkbox if you want to send emails with subscription details to the clients.
{% endstep %}

{% step %}
Leave the option **Make a 'subs' balance operation after a new subscription and an 'unsub' balance operation after unsubscription** enabled. If you don't want to make zero balance operations with comments on the master and investment accounts for this particular subscription, disable this option.

Refer to the section named [Settings for tracking subscriptions](/admin-guide/configure-b2copy/configure-copy-trading-and-mam-settings.md#settings-for-tracking-subscriptions) in [Configure copy-trading and MAM settings](/admin-guide/configure-b2copy/configure-copy-trading-and-mam-settings.md) to learn more about this option.
{% endstep %}

{% step %}
Click **Save** to create the subscription.
