# Fees

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

* 🔗 **Network Fee** — paid for executing transactions on the TON blockchain;
* ⚙️ **Storm Trade Protocol Fee** — paid for using the platform and executing trades.

***

## 🔗 TON Blockchain Network Fee

The network fee consists of several components and is calculated based on various factors such as transaction size, content, network state, and execution time.

> 💡 **Note:** It's difficult to predict the exact amount of the network fee in advance. That's why many services temporarily reserve a higher amount and refund the unused portion after the transaction is complete.

On Storm Trade, approximately **\~0.25 TON** is deducted when opening a position. **\~0.17 TON** is usually refunded back to the user’s wallet after execution.

### 📐 Network Fee Calculation Formula:

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

| ------------------ | --------------------------------------------------------------------------- |
| `storage_fees`     | Fee for storing the smart contract in the blockchain when sending/receiving |
| `in_fwd_fees`      | Fee for delivering inbound external messages                                |
| `computation_fees` | Fee for executing code in the TON Virtual Machine (TVM)                     |
| `action_fees`      | Fee for executing smart contract actions                                    |
| `out_fwd_fees`     | Fee for sending outbound internal messages                                  |

## ⚙️ Storm Trade Protocol Fee

This fee is charged when **opening and closing a position** and is automatically deducted from the margin amount.

### 📊 Fee rates depend on the trading pair:

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

> 💡 **Example:**\
> If you open a **100 USDT** position with **10x leverage** in a USDT pair:\
> `100 * 10 * 0.0012 = 1.2 USDT` will be charged as a trading fee.

## 🕒 Funding

**Funding** refers to hourly payments between traders on opposite sides of the market, commonly used in perpetual futures trading.

### 🔁 How funding works:

* If the majority opens long positions and funding turns positive:
  * 💸 **Long traders pay, short traders receive.**
* If the market is dominated by short positions and funding turns negative:
  * 💸 **Short traders pay, long traders receive.**

> 📌 Funding helps maintain the balance between supply and demand in perpetual futures markets.
