TidePerpHow TidePerp measures what it shows: every number is an observation with a source, a calculation with a published formula, or a labelled estimate. This page is generated from the same definitions the pipeline runs; the REST and WebSocket reference lives under API.
Each instrument has a canonical code VENUE:PERP:BASE:SETTLEMENT:STYLE, for example HYPERCORE:PERP:BTC:USDC:LINEAR. Builder-deployed DEXs on HyperCore are separate venues (HYPERCORE-XYZ) because they have their own order books, fees and operators.
Instruments on the same underlying form a comparison group (BTC_PERPETUAL). Within a group, DIRECT instruments share the settlement asset and are ranked as is; NORMALIZED instruments settle in a different USD-pegged asset and are ranked with a disclosure; NON_COMPARABLE instruments differ in contract terms and are listed but never ranked. Aggregates (volume, open interest, market share) include DIRECT and NORMALIZED instruments on HyperCore-native and Elysium-native venues only.
Symbols such as kPEPE keep their source symbol; the unit multiplier (1,000) is recorded in the specification so prices and sizes are never silently rescaled.
| Metric | Formula | Units | Notes |
|---|---|---|---|
| Order-book imbalance | (D_bid − D_ask) ÷ (D_bid + D_ask) | ratio | note: Descriptive measure of visible depth, not evidence of directional intent. |
| Order-book depth within band | Σ price_i × size_i over bid levels with price ≥ mid × (1 − b) and ask levels with price ≤ mid × (1 + b) | USD | bands_bps: [10,50,100,200] source_depth: at most 20 levels per side (HyperCore l2Book) |
| Hypothetical execution cost | Walk visible levels best-first until filled; VWAP = Σ p_i q_i ÷ Σ q_i; slippage_bps = |VWAP − mid| ÷ mid × 10,000; total = half-spread cost + impact + fees | USD / bps | impact: |VWAP − best opposite| × filled quantity spread_cost: |best opposite − mid| × filled quantity reference_price: mid of the snapshot insufficient_depth: returns INSUFFICIENT_OBSERVED_DEPTH; never extrapolates beyond observed levels |
| Annualized funding rate |
| Detector | Description | Parameters | Enabled |
