Fees

Trading fees are charged when opening and closing perpetual positions on TTT.

Fees are calculated based on the total position size, not the margin amount used.

Fee Structure

Maker Fee

A Maker order adds liquidity to the order book.

This usually happens when a Limit Order is placed at a custom price and is not filled instantly.

Example

BTCUSDC current price: 80,000 USDC

You place a Buy Limit order at 79,000 USDC.

The order remains open in the order book until the market reaches the selected price.

This order is considered a Maker order.

Taker Fee

A Taker order removes liquidity from the order book.

This usually happens when:

• A Market Order is executed instantly;
• A Limit Order is matched immediately against existing orders in the order book.

Example

BTCUSDC current price: 80,000 USDC

You place a Market Buy order.

The order executes instantly using available market liquidity.

This order is considered a Taker order.

Trading Fee Formula

Trading fees are calculated using the total position size:

Trading Fee = Position Size × 0.04%

Calculation Example

• Margin: 100 USDC
• Leverage: 20x

Position size:

100 × 20 = 2,000 USDC

Opening Trading fee

2,000 × 0.0004 = 0.8 USDC

Result:

• Opening fee: 0.8 USDC

Closing Fee Formula

Closing Fee = (Position Size + PnL) × 0.04%

Example

Opened position:

• Position size: 2,000 USDC
• Opening fee:

2,000 × 0.0004 = 0.8 USDC

Position later grows to 2,300 USDC because of profit.

Closing fee:

2,300 × 0.0004 = 0.92 USDC

So:

• Opening fee: 0.8 USDC
• Closing fee: 0.92 USDC

If the position is in loss, the closing fee becomes lower instead.

Total trading fees for the full trade:

0.8 + 0.92 = 1.72 USDC
