With up to 125x leverage, you can control larger positions and amplify potential profits, but remember—higher leverage also means higher risk. {% hint style="success" %} **Trade-to-Airdrop:** Every time you trade, you earn $HOPIUM based on your trading volume. The more you trade, the greater the rewards!

This opens a Long/Buy position. If you're right, your profit is based on how much the price increases, multiplied by your leverage and the amount you invested. * Alternatively, choose **`↓ Short`** if you expect the asset's price to fall. This opens a Short/Sell position, and you'll make a profit if the price goes down.
#### Choose **Position Size** & Leverage * **Volume (Position size)** refers to the initial value of your position in $USDT, which is determined by multiplying Margin by leverage: `Volume = Margin x Leverage` > For example, if you put 1,000 $USDT into your Position Size with 20X Leverage, you're only using 50 $USDT Margin. * **Leverage** works like a multiplier, lets you trade bigger with less upfront, amplifying your potential profits if the price moves in your favor—but be careful, as it can also lead to significant losses if the market moves against you. * **Margin** is the amount of $USDT you borrow to open and maintain a position. #### Cost When you open a position, you are borrowing $USDT to fund that position, which is referred as **Margin** and paying a small **Fee.** **`Cost = Margin + Fee`** *** ### **Trigger Price** {% hint style="info" %} When you set the Entry price for Limit Order, there is a range of Max Price and Min Price. This is due to the **Full Order Matching** and **Trigger Price** mechanisms. {% endhint %} To ensure Copy Trading always works smoothly, the platform does not support **Partial Order Matching**. Instead, it exclusively uses **Full Order Matching**. This means that when the **Trigger Price** is reached, the entire order is executed in one go, ensuring no remaining quantity is left unfilled. Therefore, the **Trigger Price** is applied to ensure **Full Order Matching** works effectively. The **Trigger Price** is the price level at which open orders are triggered. This includes open limit orders, close orders (stop-loss and take-profit orders), and more. The **Trigger Price** is determined by the following parameters: * **Minimum Trigger Price**: The lowest possible price that can be set. * **Maximum Trigger Price**: The highest possible price that can be set. * **Price Distance Ratio**: The minimum percentage difference between the trigger price and the market price at the time of setting the order. These parameters vary for each trading pair.
