Margin Trading

Description: Trade with borrowed funds to amplify position size.

Leverage: Up to 10× for major pairs (BTC/USDT, ETH/USDT)

Margin Types:

• Cross Margin: All account balance used as collateral

• Isolated Margin: Only allocated margin used as collateral

Interest Rates:

Asset	Hourly Rate	Daily Rate	Annual Rate
USDT	0.002%	0.05%	18.25%
BTC	0.001%	0.025%	9.13%
ETH	0.0015%	0.0375%	13.69%

Margin Calculation: $Required\_Margin = \frac{Position\_Value}{Leverage}$

Example:

• Position: $100,000 BTC

• Leverage: 5×

• Required Margin: $100,000 / 5 = $20,000

Liquidation: Occurs when equity falls below maintenance margin (see Risk Engine section for formulas).

Perpetual Futures

Description: Futures contracts with no expiration date, tracking spot price through funding rates.

Leverage: Up to 100× for BTC/ETH, lower for other assets

Funding Rate: $Funding\_Rate = Clamp(Premium\_Index, -0.05\%, +0.05\%)$

Where: $Premium\_Index = \frac{Perpetual\_Price - Mark\_Price}{Mark\_Price}$

Funding Interval: Every 8 hours (00:00, 08:00, 16:00 UTC)

Example:

• Perpetual Price: $50,100

• Mark Price: $50,000

• Premium: ($50,100 - $50,000) / $50,000 = 0.2%

• Funding Rate: 0.2% (within ±0.05% bounds)

• Long positions pay 0.2% to short positions

Position Limits:

Asset	Max Position (Notional)	Max Leverage
BTC	$10M	100×

Advanced Order Types

Time-Weighted Average Price (TWAP)

Purpose: Execute large orders gradually to minimize market impact.

Parameters:

• Total quantity

• Time window (e.g., 1 hour)

• Slice interval (e.g., every 5 minutes)

Execution: $Slice\_Size = \frac{Total\_Quantity}{Number\_of\_Slices}$

Example:

• Total: 100 BTC

• Window: 1 hour

• Interval: 5 minutes

• Slices: 12

• Size per slice: 100 / 12 = 8.33 BTC every 5 minutes

Volume-Weighted Average Price (VWAP)

Purpose: Execute orders in proportion to market volume.

Execution: Order size adjusted based on recent volume patterns.

Target: Achieve execution price close to VWAP over the period.

Iceberg Orders

Purpose: Hide large order size to prevent market impact.

Parameters:

• Total quantity

• Visible quantity (tip of iceberg)

Execution: As visible portion fills, new portion becomes visible.

Example:

• Total: 100 BTC

• Visible: 5 BTC

• Execution: Show 5 BTC, when filled, show next 5 BTC, repeat

Portfolio Margin (Planned Q3 2025)

Description: Risk-based margining that considers portfolio-level risk rather than position-level.

Benefits:

• Lower margin requirements for hedged positions

• More capital-efficient

• Suitable for sophisticated traders

Risk Calculation: $Portfolio\_Risk = \sqrt{\sum_{i,j} w_i w_j \sigma_i \sigma_j \rho_{ij}}$

Where:

• w = position weights

• σ = volatilities

• ρ = correlations

Example:

• Long BTC, Short ETH (80% correlated)

• Individual margins: $10k + $8k = $18k

• Portfolio margin: $12k (33% reduction due to correlation)

Copy Trading (Planned 2026)

Description: Automatically replicate trades of successful traders.

Features:

• Follow multiple traders

• Allocate percentage of capital per trader
