### What Are AR Perpetual Futures?

**AR perpetual futures** are leveraged derivatives that allow traders to go **long or short on Arweave (AR)** without owning the underlying token.

* **Long AR Perpetual:** Profit when AR price rises.
* **Short AR Perpetual:** Profit when AR price falls.

Unlike traditional futures, **perpetuals never expire**. Instead, they use **funding payments** exchanged between longs and shorts to maintain alignment with the spot AR market price.

### AR Perpetual Funding Rate Explained

The **PowerTrade AR funding rate** ensures AR perpetual prices stay aligned with the **CoinGecko AR/USDC Index**, reflecting the true market value of Arweave.

**Funding Rate Formula:**

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

Where:

* **P (Premium Index):** The difference between market and index prices.
* **I (Interest Rate):** 0.01% per 8 hours (applied hourly).
* **Clamp:** Restricts adjustment to ±0.05% to prevent extreme spikes.

Funding is **applied hourly** and affects only positions open at settlement.\
Traders who close positions before funding time **don’t pay funding fees**.

### AR/USDC Index Price Methodology

The **AR/USDC Index** tracks Arweave’s fair market value in USDC, using real-time data aggregated from multiple exchanges through **CoinGecko’s composite feed**.

📊 **Reference Source:** [Arweave (AR) on CoinGecko](https://www.coingecko.com/en/coins/arweave)

#### Purpose of the Index

The index ensures **mark prices and liquidation levels** reflect the **global consensus price** for AR, protecting traders from exchange-specific volatility or manipulation.

#### Index Construction

The CoinGecko composite index aggregates spot AR/USDC (or equivalent) prices across top global exchanges. Each venue’s contribution is weighted by:

* Trading volume and liquidity depth
* Exchange reliability and uptime
* Consistency with the global average

Outlier and stale data are automatically filtered out.\
PowerTrade then applies this validated CoinGecko feed to derive mark and index prices used across the platform.

#### Fallback Mechanism

If CoinGecko’s feed is temporarily unavailable, PowerTrade switches to an **internal pre-market index** based on **AR perpetual order book bid/ask data**, ensuring uninterrupted pricing and liquidation accuracy.

***

### Mark Price and Liquidation Logic

PowerTrade’s **mark price mechanism** smooths volatility and ensures fair PnL and liquidation calculations.

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

* The **EMA (Exponential Moving Average)**, calculated over 15 seconds, filters out short-term noise.
* This reduces unnecessary liquidations and keeps pricing consistent during volatile periods.

**PnL Formulas:**

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

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

When triggered:

1. Open orders are canceled.
2. Positions close at market.
3. The **insurance fund** and **auto-deleveraging (ADL)** mechanisms maintain system stability.
