# Configure trading settings for copy trading and MAM
Use these general settings to control how positions are copied in copy trading and MAM, and to track subscription and unsubscription actions with zero-balance operations and associated comments on master and investment accounts.
To configure trading settings:
{% stepper %}
{% step %}
Expand the **Copy Trading** or **MAM** menu.
{% endstep %}
{% step %}
Go to **Settings**.
{% endstep %}
{% step %}
If you have several platform instances (such as MT4, MT5, or cTrader), make sure you are in the correct instance, or go to it using the switcher in the upper-left page corner.
{% endstep %}
{% step %}
On the **Trading Settings** tab, adjust the following options:
Trading settings
### General Trading Settings
**Copy opened positions to new investors**
Default: Enabled
* **Enabled** — when an investor subscribes, all existing open positions from the master account are copied to their investment account.
* **Disabled** — existing open positions aren't copied upon subscription; only positions opened on the master account after the subscription is created will be copied to the investment account.
***
**Copy only losing positions**
Default: Disabled
* **Enabled** — when an investor subscribes, only positions that are currently losing are copied to the investment account. This allows investors to enter at more favorable prices and potentially achieve a better profit-to-loss ratio.
* **Disabled** — all positions from the master account are copied to the subscribed investment account, regardless of their current performance.
For example, suppose a trader opens a position with a potential profit of 80 points and a potential loss of 40 points.
* If an investor copies this position when its price has become 20 points lower than the trader's opening price, the investor may earn 100 points and lose 20 points.
* If the investor copies this position when its price has become 20 points higher than the trader's opening price, the investor may earn only 60 points and lose as much.
***
**Copy on resub**
Default: Disabled
* **Enabled** — during resubscription, the system copies open positions on the master account to the investment account.
* **Disabled** — no open master positions are copied during resubscription. Only positions opened on the master account **after resubscription** will be copied to the investment account.
***
**Copy only new on resub**
Default: Disabled\
Applies only if: **Copy on resub** is enabled
* **Enabled** — during resubscription, the system copies only those open master positions for which no positions were previously opened on the investor account.
* **Disabled** — all open master positions are copied to the investment account, including those that were copied earlier.
{% hint style="info" %}
If you don't want any open positions from the master account to be copied to the subscribed investment account during resubscription, disable both **Copy on resub** and **Copy only new on resub**. In this case, only new positions opened on the master account **after resubscription** will be copied to the investment account.
{% endhint %}
***
**Keep positions on unsub**
Default: Disabled
* **Enabled** — retains open positions on the investment account that were copied from the master account during unsubscription.
* **Disabled** — closes all open positions on the investment account that were copied from the master account during unsubscription.
***
**Copy only matching price group symbols**
Default: Disabled
* **Enabled** — copies positions from the master account to the subscribed investment account only if the trading symbols match exactly, ignoring symbol mapping settings and suffixes.
* **Disabled** — copies positions from the master account to the subscribed investment account regardless of exact trading symbol matching, using the symbol mapping settings and suffixes (for details, refer to [Configure symbol mapping](/admin-panel-guide/manage-b2copy-settings/configure-symbol-mapping.md)).
***
**Copy positions to read only accounts**
Default: Enabled
{% hint style="info" %}
For MAM, this option is always enabled and can't be configured.
{% endhint %}
* **Enabled** — copies positions to read-only investment accounts.
* **Disabled** — doesn't copy positions to read-only investment accounts.
### Balance Operations
Use these settings to automatically create zero-balance operations with comments on master and investment accounts whenever subscriptions are created or terminated. The comments indicate when accounts are subscribed or unsubscribed, which can be helpful for tracking and analyzing operations on client accounts.
**Balance operation after subscription/unsubscription (master)**
Default: Enabled
* **Enabled** — whenever a subscription to or unsubscription from a master account occurs, a zero-balance operation is created on the *master* account with the respective comment:
`subs | `
`unsub | `
* **Disabled** — no zero-balance operations are created on the master account upon subscription or unsubscription.
***
**Balance operation after subscription/unsubscription (investor)**
Default: Enabled
* **Enabled** — whenever an investment account is subscribed to or unsubscribed from a master account, a zero-balance operation is created on the *investment* account with the respective comment:
`subs | `
`unsub | `
* **Disabled** — no zero-balance operations are created on the investment account upon subscription or unsubscription.
{% endstep %}
{% endstepper %}
