Open Interest (OI)

Unlike spot trading where only "Volume" matters, perpetual trading introduces Open Interest. This represents the total number of outstanding derivative contracts that have not been settled.

Market Sentiment
High Open Interest suggests high liquidity and interest in a particular asset. If price rises and OI rises, it often signals a strong bullish trend.

Volume vs. Liquidity

Volume tells you how much has been traded in a specific timeframe (e.g., 24h). Liquidity tells you how easily you can enter or exit a position without moving the price.

Trading Volume

The total dollar value of all trades executed. High volume usually means more price action.

Orderbook Depth

The "thickness" of buy and sell orders. Deep orderbooks mean less slippage for large trades.

Oracle and Mark Price

Perpetual exchanges use a multi-price system to prevent "flash liquidations" caused by temporary price spikes on a single exchange.

  • Index Price: The average spot price of the asset across major exchanges (Binance, Coinbase, etc.).
  • Mark Price: The price used for calculating liquidations. It is based on the Index Price plus a decaying funding basis.
  • Oracle Price: The decentralized price feed provided by the network to ensure fairness.

On-Chain Data Analysis

Because Hyperliquid is a transparent Layer 1 blockchain, every trade, liquidation, and funding payment is public. Professional traders use this data to spot institutional moves and "whale" activity before it reflects on the retail charts.

Transparency Benefit
On Dexly, you aren't trading against a "black box." You are trading against a global, verifiable orderbook.

Risk Warning: Trading perpetual futures involves significant risk of loss. Only trade with capital you can afford to lose. Dexly is a non-custodial interface; you are responsible for your own funds and trading decisions.
