{% step %}
In the **Risk limit** section, enter or edit the value in the **Loss Limit (Max loss amount)** field. This is the maximum loss amount that the subscribed investment account can bear from the selected subscription. If the assigned risk limit is exceeded, the subscription will be automatically terminated.

{% hint style="info" %}
Risk limits for subscriptions are always denoted in the currency in which the subscribed investment account is denominated. ‍ A risk limit can be specified as a positive or negative value (such as 500 or -500). In either case, it represents a loss on the investment account.
{% endhint %}

For more details about risk limits that can be assigned to subscriptions, refer to [Risk limits for investors](https://docs.b2copy.b2broker.com/copy-trading-pamm-and-mam-concepts/risk-limits-for-investors).
{% endstep %}

{% step %}
For copy-trading and MAM subscriptions, you can edit the following settings in the **Allocation parameters** section:

* In the **Allocation Method** dropdown, select the method that you want to use to calculate position sizes when open positions are copied from the master account to the subscribed investment account.

To learn more about allocation methods, refer to [Allocation methods for copy trading and MAM](https://docs.b2copy.b2broker.com/copy-trading-pamm-and-mam-concepts/allocation-methods-for-copy-trading-and-mam).

* In the **Risk Ratio** field, edit the risk ratio assigned to the subscription. The risk ratio is used to recalculate the size of positions that are copied from the master account to the subscribed investment account.

The risk ratio only applies to the allocation methods that use it in their formulas.

* In the **Reverse Trading** dropdown, select either **Norma**l or **Reverse.**
  * If **Normal** is selected, the trade side of positions open on the master account doesn't change when they are copied to the subscribed investment account. For example, if a master trader opens a *sell* position, this position is copied as a *sell* position for an investor.
  * If **Reverse** is selected, the trade side of positions opened on the master account is changed when they are copied to the subscribed investment account. For example, if a master trader opens a *sell* position, this position is copied as a *buy* position for an investor.

In the **Fee Plan ID** section, you can change the fee plan applied to the subscription by clicking the **Edit** button and selecting another plan from the list of fee plans created for the master account.
