# Fees

**Storm Trade users pay two types of fees:**

* 🔗 **Network fee** — for executing a transaction on the TON blockchain;
* ⚙️ **Storm Trade protocol fee** — for using the platform and performing trading operations.

***

## 🔗 TON blockchain network fee

The network fee consists of several components and is calculated based on many factors: the size and content of the transaction, network conditions, processing time, and so on.

> 💡 **Important:** The exact fee cannot be predicted in advance. This is why most services reserve an amount with a buffer and return the remainder to the user once the transaction is complete.

On Storm Trade, opening a position charges around **\~0.25 TON**, of which **\~0.17 TON is returned** to the user's wallet.

### 📐 Network fee formula:

$$
Transaction Fee = Storage Fees + In Fwd Fees + Computation Fees + Action Fees + Out Fwd Fees

## ⚙️ Storm Trade protocol fee

The platform fee is charged when **opening and closing a position** and is deducted automatically from your collateral.

### 📊 The fee depends on the trading pair:

* 💰 For **USDT pairs** — from **0.06%** to **0.12%**
* 💎 For **TON/NOT pairs** — from **0.12%** to **0.2%**
* 💵 For **Forex pairs** — **0.06%**
* 🪙 For **Gold** — **0.08%**

> 💡 **Example:**\
> Opening a **100 USDT position with 10x leverage** on a USDT pair:\
> `100 * 10 * 0.0012 = 1.2 USDT` will be charged as a fee.

## 🕒 Funding

**Funding Fee** is a recurring (hourly) payment between traders holding opposite positions, used in perpetual futures trading.

### 🔁 How funding works:

* If most traders go long and funding turns positive:
  * 💸 Long traders pay, short traders receive.
* If shorts dominate the market and funding turns negative:
  * 💸 Short traders pay, long traders receive.

> 📌 Funding helps balance supply and demand in the perpetual futures market.
