Before we start...

If you use a Portfolio Margin account, please read this information carefully!

When creating API keys, there is a choice of account - Classic or Portfolio Margin Account. If you choose a Portfolio Margin account, you may receive an error such as:
Portfolio_margin_account can only set the account CROSS_MARGIN.

The workaround for trading on a Spot account is to use a Classic Account instead of a Portfolio Margin Account.

More details about the Portfolio Margin Account you can find here.

REMINDER!

If you intend to trade Futures with Gate.io, please ensure you have a little BTC and/or USDT transferred to the respective BTC Perpetual and USDT Perpetual wallets before you link to 3Commas, or you may see this error message:

Before adding the API key to 3Commas, you will need to Transfer some BTC and USDT to your Perpetual Futures Account https://www.gate.io/myaccount/myfunds/futures, and only then Gate.io will allow you to add Perpetual accounts to 3Commas as well.
