On Binance, to use a **stop loss**, here are the steps to follow and how to fill in the boxes:

1. **Access your Binance account** and go to the trading section (Spot or Futures depending on what you are trading).

2. **Select the Stop-Loss order**:

- Click on the "Buy/Sell" button for the asset you want to trade.

- In the order type menu, choose "Stop-Limit" or "Stop-Market". The stop-limit allows you to set a trigger price and a limit price, while the stop-market will sell the asset at the market price once the stop is triggered.

3. **Fill in the boxes**:

- **Stop (Trigger Price)**: This is the price at which you want your stop loss to be triggered. For example, if you buy a crypto at €100, you can set a stop at €95.

- **Limit**: This is the price at which you want to sell once the stop is triggered. This price is often set close to the trigger price (e.g., €94 if the stop is at €95).

- **Quantity**: Indicate the number of coins or units you want to sell once the stop is triggered.

4. **Place Order**: After filling in the information, click **"Sell"** or **"Buy"** to place the order with stop loss.
