### What Are ATH Perpetual Futures?

**ATH perpetual futures** are leveraged derivative contracts that let traders go **long or short on Aethir (ATH)** without owning the underlying token.

* **Long ATH Perpetual:** Profit when ATH’s price increases.
* **Short ATH Perpetual:** Profit when ATH’s price decreases.

Unlike dated futures, **ATH perpetuals never expire**. Instead, they rely on **hourly funding payments** between long and short traders to keep prices in line with ATH’s spot market value.

### ATH Perpetual Funding Rate Explained

PowerTrade’s **ATH funding rate** ensures the perpetual contract price stays aligned with the **ATH/USDC Index**, derived from [**CoinGecko**](https://www.coingecko.com/en/coins/aethir).

**Funding Rate Formula:**

```
F = P + clamp(I – P, +0.05%, –0.05%)
```

Where:

* **P (Premium Index):** Difference between the market and index prices.
* **I (Interest Rate):** 0.01% per 8 hours (applied hourly).
* **Clamp:** Restricts adjustments to ±0.05% to prevent extreme funding changes.

Funding is **applied hourly** and affects only positions open at settlement.\
Traders who close positions before the funding timestamp **avoid paying funding fees**.

### ATH/USDC Index Price Methodology

The **ATH/USDC Index** represents the fair, real-time market value of Aethir (ATH) against USDC, using aggregated spot data from **CoinGecko’s composite exchange feed**.

📊 **Reference Source:** [Aethir (ATH) on CoinGecko](https://www.coingecko.com/en/coins/aethir)

#### Purpose of the Index

The index acts as the **reference rate** for ATH perpetual contracts, ensuring fair pricing and protecting traders from single-exchange volatility.\
It’s used to determine mark prices, liquidation levels, and funding calculations.

#### Index Construction

CoinGecko’s composite index aggregates ATH/USDC (or equivalent pairs) from multiple reputable exchanges and weights them by:

* Trading volume and liquidity depth
* Historical uptime and data reliability
* Consistency with global market averages

CoinGecko automatically excludes stale or anomalous data to maintain index integrity.\
PowerTrade integrates this validated feed to ensure accurate and manipulation-resistant pricing.

#### Fallback Mechanism

If CoinGecko’s data feed becomes unavailable, PowerTrade switches to an **internal pre-market index** using **bid/ask data** from the ATH perpetual order book.\
This guarantees continuous pricing and fair liquidations even during external data outages.

***

### Mark Price and Liquidation Logic

PowerTrade’s **mark price mechanism** ensures consistent and fair PnL calculations across all perpetual markets.

```
Mark Price = Index Price + EMA(Market Price – Index Price)
```

* The **EMA (Exponential Moving Average)** is calculated over a 15-second window to smooth out volatility.
* This mechanism minimizes unfair liquidations and ensures stability during fast price swings.

**PnL Formulas:**

* **Long ATH:** `PnL = Position Size × (Mark Price – Entry Price)`
* **Short ATH:** `PnL = Position Size × (Entry Price – Mark Price)`

**Liquidation Trigger:**\
`Account Balance + Unrealized PnL ≤ Maintenance Margin`

Upon liquidation:

1. All open orders are canceled.
2. Positions are closed at market.
3. PowerTrade’s **insurance fund** and **auto-deleveraging (ADL)** system safeguard the market and other traders.
