How do I add the balance I would like a signal provider to use?
For Signal Provider services, you will need to add the position size within the settings tab on the service profile page.
The position size will be the amount used for each trade opened from this signal provider
If you select USDT for example, the signal provider will open trades in USDT pairs; (LINK/USDT, ETH/USDT etc.)
Be sure your exchange account wallet has enough funds in this coin to cover these trades.
