How do I make a buy trade with an automatically triggered stop loss using the Binance app?

Hi

I would like to make a buy trade then go to bed knowing that Binance will automatically sell my order at my stop loss if the price falls too low.

For example:

The current price of ETH is 3200 USDT

I place an order to buy ETH if the price falls to 3000 USDT

But I also want to set a stop loss at 2955 just in case the price falls further.

Currently, the only way I can do this is by making a buy trade now and then making another trade, setting the stop loss.

I would like to know if it's possible to combine the two actions in one trade. And how this is done.

Many thanks
