Binance Futures recently release a new Hedge Mode feature.
Unfortunately from our own testing and from several user feedbacks we have received, 3Commas Bots and Smart Trades will not work if Hedge Mode is enabled on your Binance Futures linked account.
If you have enabled Hedge Mode, please disable it and if you experience problems creating new Bot deals or Smart Trades after disabling Hedge Mode, you will need to delete the API on the Binance Futures web-site and create a new API.
Once this is done, you can edit your linked account in 3Commas and update the API key and Secret to resolved these issues.
Our Product Development Team will look at ways we can implement this new feature within 3Commas to release at a future date.
