The minimal requirement is a Binance or Houbi account connected to 3commas via API. If you use Binance, the account must have BNB and BNB fees turned on. This is a necessary condition. Without it, the bot will work with issues. Enabling the BNB fees protects trades from leaving a "dust" (small amount of coins is not sold due to Binance order size limitations) and makes orders finishing faster.
Necessarily check out all information in this section.
After that, you can go to “My bots” section in 3commas menu and create your first bot. We strongly recommend you to use minimum possible volumes and % of profits in first trades to understand how the bot works and how its settings impact on his workflow.
