### What Are ARB Perpetual Futures?

**ARB perpetual futures** are leveraged derivative contracts that allow traders to take **long** or **short** positions on the price of **Arbitrum (ARB)** without owning the underlying token.

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

Unlike dated futures, **ARB perpetuals never expire**. Instead, they rely on **funding payments** exchanged between long and short traders to keep contract prices aligned with the ARB spot market.

### ARB Perpetual Funding Rate Explained

PowerTrade’s **ARB funding rate** mechanism ensures perpetual prices remain closely aligned with the **ARB/USDC index** derived from [**CoinGecko**](https://www.coingecko.com/en/coins/arbitrum).

**Funding Rate Formula:**

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

Where:

* **P (Premium Index):** Difference between perpetual market price and index price.
* **I (Interest Rate):** 0.01% per 8 hours (applied hourly).
* **Clamp:** Restricts change to ±0.05% to prevent funding volatility.

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

### ARB/USDC Index Price Methodology

The **ARB/USDC Index** tracks Arbitrum’s fair market value against USDC using aggregated real-time data from **CoinGecko’s composite feed**.

📊 **Reference Source:** [Arbitrum (ARB) on CoinGecko](https://www.coingecko.com/en/coins/arbitrum)

#### Purpose of the Index

The index ensures **mark prices** and **liquidation thresholds** reflect the true global market value of ARB — rather than activity on a single exchange.\
This design promotes **fairness, transparency**, and **market integrity**.

#### Index Construction

The index is derived from a weighted average of ARB/USDC (or equivalent) spot prices across major exchanges.\
Each source’s weight is determined by:

* Trading volume and liquidity
* Historical reliability and uptime
* Price stability versus global averages

CoinGecko automatically excludes stale or outlier data to ensure consistency.\
PowerTrade uses this validated feed to calculate mark prices and funding rates.

#### Fallback Mechanism

If CoinGecko’s data feed becomes unavailable, PowerTrade switches to an **internal pre-market index**, derived from **bid/ask data** in the ARB perpetual order book.\
This ensures continuous pricing and fair liquidations even during data disruptions.

***

### Mark Price and Liquidation Logic

PowerTrade’s **mark price mechanism** ensures fair and transparent PnL calculations and liquidation processes.

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

* The **EMA (Exponential Moving Average)** is computed over a 15-second window to smooth short-term volatility.
* This protects traders from unnecessary liquidations and ensures accurate mark-to-market pricing.

**PnL Calculations:**

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

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

When triggered:

1. All open orders are canceled.
2. Positions close at market price.
3. The **insurance fund** and **auto-deleveraging (ADL)** system protect other traders from loss propagation.
