Fees

Flash Trade implements a dynamic fee structure across different asset pools. Understanding these fees is essential for optimizing your trading strategy.

Overview

All trading fees consist of three main components:

• Open/Close Fees - Charged when opening or closing positions

• Margin Fees - Continuous fees on open positions based on utilization

• Swap Fees - Applied when using different collateral assets
