From anywhere on the site you have the button to create an order. It gives you the opportunity to make a trade with your hands. There are two ways to trade in a group:
Create a group, adding there all the keys except one and trade on it in any terminal. Create a bot copy for him and he will copy all actions from him to the group.
Create a group in which all the keys are added and make trades on it in our terminal.
The terminal allows not only to make transactions for a group, but also for one key. You can always adjust any trade according to your key. In the terminal section you will also see consolidated data on all your keys (positions, open orders, stops)
