1. Unrealized PnL
Once an order is filled, you can view the position and the unrealized PnL in your "Position" section.
The formula for calculating unrealized PnL varies slightly depending on your trading direction.
Unrealized PnL on long positions = position size x (last price - avg. position price)
Unrealized PnL on short positions = position size x (avg. position price - last price)

Notes:
1) The calculation of unrealized PnL does not include any trading or funding fees incurred or received while opening, closing or holding positions.
2) The unrealized PnL is calculated based on the last market price by default. Tap on the Unrealized PnL to switch the price benchmark to either the Mark Price or the Last Price.
3) Increasing leverage will not directly amplify your profits or losses. Profits and losses are determined by position size and price fluctuations. Higher leverage means less margin is needed to open a position, while a larger position amount leads to bigger profits or losses. The larger the price difference between the last price and the opening price, the more significant the potential gains or losses become.

2. PnL Ratio (%)
The PnL ratio, also known as the unrealized PnL percentage, displays the return on investments (ROI) for this position in percentage format. Similar to unrealized PnL, this figure fluctuates along with the last market price. Here's how to calculate the PnL ratio:

Note:
1. Increasing leverage will not directly affect your unrealized PnL. Users may sometimes notice an increase in the unrealized PnL ratio but it's mainly due to a reduction in your position margin and not because of an increase in actual profits.
2. In cross margin mode, the position margin will always be calculated based on the maximum leverage allowed within the current risk limit for the particular crypto.

3. Realized PnL
Realized PnL = closed position PnL - trading fees - funding fees incurred while holding the position
