1. Overview
Use these fields in REST query parameters or WebSocket subscriptions to select sessions and price adjustments.
Supported adjustments depend on the symbol type. Inapplicable parameters are ignored.
2. Symbol Types
| Symbol Type | Examples | Applicable Parameters |
|---|---|---|
| Equities / ETFs | NASDAQ:AAPL, NASDAQ:QQQ | extended, split, dadj |
| Futures (specific expiry) | COMEX:GCM2026 | settlement |
Futures (continuous — 1! / 2!) | COMEX:GC1!, COMEX:GC2! | badj, settlement |
| Others | Forex, crypto, indices, bonds, etc. | None — adjustment parameters are ignored |
3. Common Parameters
| Parameter | Default | Description |
|---|---|---|
| extended | true | Include extended/pre-post market trading hours data. Only applies to non-futures symbols — futures always use the extended session regardless of this value. |
| currency | symbol default | Convert OHLCV data to a different currency. Must be a valid ISO 4217 currency code (e.g., USD, EUR, GBP). Omit to use the symbol's native currency. |
4. Equity & ETF Parameters
Apply to equities and ETFs only.
| Parameter | Default | Description |
|---|---|---|
| split | true | Split-adjusted prices. Set to false to receive unadjusted data. |
| dadj | false | Dividend-adjusted prices. When enabled, data is both split- and dividend-adjusted. If split=false, this parameter is ignored. |
Adjustment Combinations
- Split-adjusted (default) — no parameters needed, or explicitly
split=true - Split + dividend adjusted —
dadj=true - Unadjusted —
split=false
5. Futures Parameters
Apply to futures only.
| Parameter | Default | Applies To | Description |
|---|---|---|---|
| badj | true | Continuous only (1!, 2!) | Back-adjusted prices. Smooths price gaps between contract rollovers. Has no effect on specific-expiry contracts or non-futures. |
| settlement | false | All futures | Use settlement price as the daily close instead of the last traded price. |
6. Series-Only Parameters
Apply to OHLCV series endpoints and WebSocket series subscriptions. For date-specific intraday requests, see History Endpoints.
| Parameter | Default | Description |
|---|---|---|
| bar_type | day | Bar interval type. One of: tick, second, minute, hour, day, week, month. |
| bar_interval | 1 | Number of units per bar. For second: one of 1, 5, 10, 15, 30, 45. For minute: 1–1440. For hour: 1–24. |
| dp | 1 | Initial data points. Defaults to 1; values above 1 round up to the next 500. Not applicable to History endpoints which use date-based retrieval. |
