The Binance Futures exchange allows to open only 1 futures position in 1 exchange account at the same time. When connecting one Binance account you can run two strategies one spot strategy and one futures strategy
So if you would like to launch 2 or more Futures strategies you need to connect additional Binance accounts via API to your GT App account.
Please add and use new Binance API connection every time you create new futures strategy.
Please don't set up 2 futures strategy under 1 exchange account because Binance exchange will not allow to open the second position.
