What Are API3 Perpetual Futures?

API3 perpetual futures are leveraged derivatives that let traders go long or short on API3 price movements without holding the underlying token.

• Long API3 Perpetual: Profit when API3 price rises.

• Short API3 Perpetual: Profit when API3 price falls.

Unlike traditional futures, API3 perpetuals never expire. Instead, they use hourly funding payments exchanged between long and short traders to maintain alignment with API3’s global spot market price.

API3 Perpetual Funding Rate Explained

PowerTrade’s API3 funding rate ensures perpetual contract prices remain in sync with the API3/USDC Index, derived from CoinGecko.

Funding Rate Formula:

F = P + clamp(I – P, +0.05%, –0.05%)

Where:

• P (Premium Index): Difference between the perpetual and index price.

• I (Interest Rate): 0.01% per 8 hours (applied hourly).

• Clamp: Limits adjustment to ±0.05% to prevent extreme funding shifts.

Funding is applied hourly and only impacts open positions at settlement. Traders who close positions before funding time pay no funding fees.

API3/USDC Index Price Methodology

The API3/USDC Index Price tracks API3’s fair market value against USDC, using data aggregated from CoinGecko’s composite exchange feed.

📊 Reference Source: API3 on CoinGecko

Purpose of the Index

The index price ensures fair and transparent pricing for API3 perpetual contracts — anchoring PowerTrade’s mark prices to a global benchmark and preventing manipulation from any single venue.

Index Construction

CoinGecko’s composite API3 index aggregates prices across major exchanges and weights them by:

• Trading volume and liquidity depth

• Exchange uptime and data reliability

• Consistency versus global market averages

Outlier and stale prices are automatically excluded to preserve data integrity. PowerTrade uses this validated index to derive its API3 mark price and liquidation thresholds.

Fallback Mechanism

If CoinGecko’s data feed becomes temporarily unavailable, PowerTrade switches to an internal pre-market index, derived from API3 perpetual bid/ask data. This ensures uninterrupted mark pricing and system stability during data disruptions.

Mark Price and Liquidation Logic

PowerTrade’s mark price mechanism ensures smooth PnL calculations and fair liquidations:

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

• The EMA (Exponential Moving Average) is calculated over a 15-second window to smooth price volatility.

• This helps minimize unnecessary liquidations and ensures mark prices reflect true market conditions.

PnL Calculations:

• Long API3: PnL = Position Size × (Mark Price – Entry Price)

• Short API3: 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 ADL systems maintain fairness and market stability.
