🧮Fees

Types of fees

Fees paid by a Storm Trade user are of two types:

• network fee, which is paid for conducting a transaction in the TON blockchain

• Storm Trade protocol fee, which is paid for using the platform

TON network/blockchain fee

The network fee consists of several components, the amount of which depends on many parameters: execution time, size, content, network condition, etc.

It is difficult to calculate the exact amount in advance, so many services reserve funds with a reserve and return the balance to the user after the transaction. For example, when performing transactions on Storm Trade, about ~0.4 TON is deducted from the wallet, the unused part of which is returned to the user's wallet.

The formula for calculating the network fee is as follows:

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

• storage_fees – fees for storing a smart contract on the blockchain, deducted when a transaction is received or sent.

• in_fwd_fees – fees for delivery of incoming external messages.

• computation_fees – fees for executing code in a blockchain virtual machine (TVM).

• action_fees – fees for processing smart contract code actions.

• out_fwd_fees – fees for import of outgoing internal messages.

Fees by Storm Trade

Storm Trade fee is charged to the user when trading operations are performed at opening and closing a position and is deducted from the collateral.

Fees make up different values in different trading pairs:

• In USDT pairs the fee is 0.12% of the position size

• In coin-margined pairs the fee is 0.2% of the position size

• In Pre-Launch markets the fee is 1% of the position size

The position size takes into account the leverage value. For example, in USDT pair, opening a position for 100 USDT with leverage x10, a trader will pay a fee of 100 * 10 * 0.0012 = 1.2 USDT.

Funding payments

Funding is an hourly payment between traders on opposite sides of the market, used by exchanges to trade perpetual futures.

All traders pay or receive funding depending on the open interest in the trading pair in which their position is open:

• If the Market Price of an asset is higher than the Index Price, the Funding is positive. In this case, the total open interest of long positions exceeds the total open interest of short positions. Funding is paid by traders who opened long positions and is credited to traders who opened short positions.

• If the Market Price of an asset is lower than the Index Price, the Funding is negative. In this case, the Funding payment is charged from traders who opened short positions and is credited to traders who opened long positions.
