# Fees

## **Service fees**

Using Contango directly via its smart contracts is free. Trading through the app incurs the following fees:

* Correlated pairs: 0.05% (5 bps) on any change of position size. This applies to TP/SL too.
* Non-correlated pairs, 0.25% (25 bps) on any change of position size. This applies to TP/SL too.

*Correlated* refers to those instruments where the base and quote asset are a flavor of the same currency, e.g. stable pairs like DAI/USDC, ETH derivative pairs like wstETH/ETH or PTeBTC/eBTC, etc.

*Non-correlated* refers to those instruments where the base and quote asset are not correlated, and are normally used for directional trading, e.g. ETH/USDC or ETH/BTC.

Service fees, as well as any other type of fee, are always displayed upfront in the UI:

Discounts to fees are applied depending on the [XP tier](/tango/tangonomics.md#f734) of each user.

**Migrations**: Currently, Contango doesn't charge fees for migrating a position to a different market. Migrating a position entails closing an existing position and opening a new one on a different market via flash loan; no swaps are needed for migrations. So, depending on the instrument you're trading, you might pay a flash loan fee if this is not provided for free (see section below), but you won't face any swap fees.

**Transfers**: [moving the NFT](/resources/faq.md#how-can-i-move-my-position-to-a-different-wallet) that represents a position to a different address is also free.

**Special cases:** positions opened before the [TANGO](/tango/tangonomics.md) launch will not be charged any closing fees.

## **Automation fees**

Beside the above fees, traders pay a reward to cover gas costs for keepers that handle [TP/SL orders](/basics/key-features/automation.md).

## **Flash loan fees**

Contango sources flash loans from different venues, some are free (e.g. Balancer, Morpho, Aave) and some aren't. Depending on the instrument you're trading, you might pay a flash loan fee. Flash loan fees are always surfaced in the opening ticket, before you place a trade.

## **Liquidation penalties**

On Contango, liquidations are carried out at the level of the underlying money market. A liquidation penalty is a fee paid on the price of the collateral when liquidators purchase it as part of the [liquidation](/basics/key-features.md#liquidations) process on the lending market. in other words, Contango is not responsible for liquidations nor it collects liquidation fees.

{% hint style="warning" %}
Liquidations on money markets have very harsh conditions. Monitor your position frequently and avoid liquidation at all costs.
