# Trading
## Opening Positions
Users can open positions by choosing either \[Buy/Long] or \[Sell/Short], utilizing leverage to enhance trading potential.
***
### **Order Types**
1. Market Order:
1. Executes immediately at the current market price, prioritizing speed over price.
2. May experience slippage due to market volatility.
2. Limit Order:
1. Executes at a specified price or better.
2. For buy orders, the trade will execute at the limit price or lower.
3. For sell orders, the trade will execute at the limit price or higher.
4. Note: If the market price doesn’t reach the specified limit price, the order may not execute.
***
### **Estimated Position Profit/Loss**
Long Position:
* Profit: Gains are realized when the price rises.
* Loss: Losses occur when the price falls.
For example:
* With 10x leverage, a 10% price increase results in a 100% profit.
* If the maintenance margin is 1.5%, an 8.5% price decrease leads to a total loss of 100%, causing the position to be liquidated.
Short Position:
* Profit: Gains are realized when the price falls.
* Loss: Losses occur when the price rises.
For example:
* With 1x leverage, a 10% price decrease results in a 10% profit.
If the maintenance margin is 1.5%, a 98.5% price increase leads to a total loss of 100%, causing liquidation.
{% hint style="info" %}
The examples focus on price movement impacts. Actual positions may incur **funding fees**, and the profit/loss figures are for reference only.\
Maintenance margin rates vary per cryptocurrency, reflecting different levels of trading risk. Review the token-specific parameters before trading.

### Position Management
Users can manage their positions directly from the trading interface.
1. Adding Margin:
1. Isolated Margin: Add or reduce margin for a specific isolated position.
1. Click the margin adjustment button to modify the margin, managing your risk exposure.
2. Note: Initial margin cannot be reduced.
3. Cross Margin: Use available balance to supplement margin and lower position risk. \
2. Liquidation Price and Margin Levels:
1. If the mark price reaches the liquidation price, the position will be liquidated, resulting in a total loss of associated margin.
2. Monitor margin levels to manage risk. If the margin level reaches or exceeds 100%, the position will be liquidated.
***
### **Stop Loss and Take Profit**
* Pre-set stop loss and take profit prices for your positions.
* Orders execute automatically when the market price reaches the set levels.
* Note: These are processed as market orders and may experience slippage.
***
### **Closing Positions**
1. Click \[Close] to close a position using either market or limit orders.
2. Alternatively, click \[Close All] to cancel all open orders and close all positions at the current market price.
