# Fees & cost structure

Atomic charges a flat fee on each trade, split equally between opening and closing a position.

| ACTION               | FEE                |
| -------------------- | ------------------ |
| Open position        | 10 bps (0.10%)     |
| Close position       | 10 bps (0.10%)     |
| **Round trip total** | **20 bps (0.20%)** |

Fees are deducted from your margin at the time of each action and distributed to lenders as yield.

**No hidden costs**\
There are no borrowing fees, no funding rates, and no fees for setting or modifying TP/SL orders.
