Glossary

Short definitions for crypto perpetual markets, order-flow concepts and Tradeiz product terms.

Definitions here are educational summaries, not investment advice. For venue-specific contract specs, always confirm with the exchange or protocol documentation.

Market & derivatives

Basis

The spread between a perpetual (or futures) price and the underlying spot or index. Persistent positive basis can accompany bullish positioning; negative basis the opposite.

See also: Index price, Mark price

Funding interval

How often a venue settles funding payments — commonly every 1h, 4h or 8h depending on the exchange or DEX. Tradeiz normalises rates for cross-venue comparison.

See also: Funding rate

Funding rate

A periodic payment exchanged between long and short positions on a perpetual contract. A positive rate means longs pay shorts; a negative rate means shorts pay longs.

See also: Perpetual, Funding arbitrage

Index price

A composite spot reference built from multiple exchanges or oracles. Venues use it to compute mark price and fair-value funding.

See also: Mark price, Basis

Leverage

Borrowed notional relative to posted margin. Higher leverage amplifies PnL and liquidation risk; Tradeiz surfaces positioning and liquidation metrics but does not offer leverage itself.

See also: Liquidation, Maintenance margin

Liquidation

Forced closure of a leveraged position when margin falls below the maintenance requirement. Liquidation events appear in Tradeiz liquidation feeds and heatmaps.

See also: Liquidation cascade, Mark price

Liquidation cascade

A chain reaction where forced closes push price further, triggering additional liquidations. Clusters are visible in cross-venue liquidation dashboards.

See also: Liquidation, Heatmap

Long/short ratio

The proportion of accounts or volume positioned long versus short on a venue. Extreme readings can flag crowded trades in sentiment dashboards.

See also: Sentiment dashboard, Open interest

Maintenance margin

Minimum collateral required to keep a leveraged position open. Falling below it triggers liquidation at the venue — not on Tradeiz.

See also: Leverage, Liquidation

Mark price

The fair-value reference price venues use for unrealised PnL and liquidation triggers, often derived from an index plus a basis component. Differs from last traded price during stress.

See also: Index price, Basis

Open interest (OI)

The total number of outstanding perpetual contracts that have not been closed. Rising OI with price often signals new positioning; falling OI can mean positions are being unwound.

See also: Perpetual, Cross-venue

Perpetual

A derivative contract with no fixed expiry that tracks an underlying index price. Perpetual swaps use funding payments to keep the contract price aligned with spot.

See also: Funding rate, Index price

Order flow & microstructure

Aggressor side

Whether a trade lifted the offer (buy aggressor) or hit the bid (sell aggressor). Tradeiz tags prints for delta and large-trade analytics.

See also: Delta, Large trades

Delta (order flow)

Net aggressive buy volume minus aggressive sell volume over a window. Positive delta suggests buyers hitting the offer; negative delta suggests sellers hitting the bid.

See also: Aggressor side, Footprint

Depth

Resting limit orders on the book at each price level. Depth heatmaps visualise where liquidity sits and how it changes over time.

See also: Order book, Heatmap

Footprint

An order-flow chart overlay showing bid/ask volume traded inside each candle, often split by price level. Helps intraday traders see absorption and aggression.

See also: Volume profile, Delta

Large trades

Individual fills that exceed a venue- or user-defined notional threshold. Surfaced in the Large Trades feed and as on-chart markers.

See also: Order flow, Real-time feed

Order book

The live queue of bid and ask limit orders for a symbol. Tradeiz streams normalised depth snapshots and updates from supported venues.

See also: Depth, WebSocket streams

Order flow

The sequence and size of aggressive and passive trades plus book changes. Order-flow tools help read who is initiating and where liquidity is consumed.

See also: Footprint, Delta

Volume profile

A histogram of volume traded at each price level over a chosen range. Highlights value areas and high-volume nodes on the chart.

See also: Footprint, Chart workspace

Venues & data model

CEX

Centralised exchange — a custodial venue that matches orders on its own infrastructure (e.g. Binance, OKX, Bybit).

See also: DEX, Cross-venue

Cross-venue

Metrics or views that aggregate or compare multiple exchanges under the same symbol and timeframe — funding, OI, liquidations and positioning dashboards.

See also: Normalised schema, Screener

DEX

Decentralised exchange or on-chain perpetual protocol where settlement occurs on a blockchain or app-chain (e.g. Hyperliquid, dYdX).

See also: CEX, Funding arbitrage

Normalised schema

Tradeiz’s unified field naming and units across venues so the same API query or chart symbol works regardless of upstream exchange quirks.

See also: REST API, Cross-venue

Real-time feed

Low-latency market data delivered over WebSocket with near-exchange timestamps. Used by the chart workspace and programmatic stream clients.

See also: WebSocket streams, Order book

Tradeiz product

Alert

A rule that notifies you when price, indicator or platform conditions are met. Delivery channels vary by subscription tier.

See also: Chart workspace, Entitlement

API key

A secret token that authenticates programmatic access to Tradeiz REST and WebSocket endpoints. Scoped by entitlements and rate limits per key.

See also: REST API, Entitlement

Tradeiz’s multi-pane chart desk: layouts, watchlists, drawings, indicators, alerts and optional YeScript panels on live market data.

See also: Layout, Watchlist

Entitlement

A feature flag tied to your subscription plan — which indicators, data feeds, AI quotas or API limits are unlocked.

See also: API key, Tradeiz AI

Funding arbitrage

Strategies that exploit funding-rate differentials between venues or between perp and spot. Tradeiz’s DEX Funding Arb page surfaces live spreads for research.

See also: Funding rate, Cross-venue

Heatmap

Colour-coded grids (e.g. RSI Heatmap, liquidation heatmap) that surface outliers and regime shifts across many symbols at once.

See also: Screener, Liquidation cascade

Layout

A saved arrangement of chart panes, symbols and settings tied to your account and restorable across sessions.

See also: Chart workspace, Watchlist

Pressure Watch

Tradeiz’s squeeze / pressure dashboard highlighting crowded positioning, funding extremes and liquidation risk clusters.

See also: Sentiment dashboard, Heatmap

REST API

Tradeiz’s HTTP JSON API for historical and snapshot market data, reference metadata and account-scoped endpoints where applicable.

See also: API key, WebSocket streams

Screener

A filterable table of symbols ranked by price change, volume, funding, OI and other metrics across venues.

See also: Heatmap, Cross-venue

Sentiment dashboard

Cross-market positioning and mood views — long/short ratios, funding & OI composites and related sentiment metrics.

See also: Long/short ratio, Pressure Watch

Tradeiz AI

The in-chart AI assistant that helps interpret market context, draft YeScript and answer product questions. Outputs are informational, not trade recommendations.

See also: YeScript, Entitlement

Watchlist

A user-curated list of symbols for quick navigation in the chart and research pages.

See also: Layout, Screener

WebSocket streams

Low-latency push channels for trades, depth, liquidations and other live feeds. Documented alongside the REST API for programmatic access.

See also: Real-time feed, REST API
