# Controlling an option in the signal
Orders are created based on Terminal settings and the received Signal message code.
By default, order settings are taken from the saved Terminal settings, except for the currency pair and order direction (buy/sell).
If you want the signal to be a **buy** signal, manually change the signal message to **`"side": "buy"`** in Tradingview signal settings.
If you want the signal to be a **sell** signal, manually change the signal message to `"side": "sell`" in Tradingview signal settings.
To manage the settings from the signal, you must check the box to the left of the header and save. The new message must be updated in the TradingView signal settings.
In this example, **Order Volume** will be managed from the Signal message.
If you need to change the **Order Volume** to **500**, manually edit the value from **100** to **500** in the signal message and **Save**.
{% hint style="warning" %}
Unchecking the option's box in the Terminal and clicking "**Save**" applies the setting from the **Terminal**, even if the signal message code contains the option.
✅ If checked - option is applied from the received Signal message.
◻ If unchecked - option is applied from the Terminal settings.
