Resolutions

CandleResolution is the SDK’s own vocabulary for bar sizes — not any single provider’s:

type CandleResolution =
  | "1s"
  | "10s"
  | "1m"
  | "3m"
  | "5m"
  | "15m"
  | "30m"
  | "1h"
  | "2h"
  | "4h"
  | "6h"
  | "8h"
  | "12h"
  | "1d"
  | "3d"
  | "1w"
  | "1M";

A CandleSource maps these onto its native interval strings and declares the subset it can actually serve via supportedResolutions — no venue supports all of them. Binance futures, for instance, has neither 1s nor 10s; Binance spot serves 1s but not 10s.

resolutionToMs

Nominal length of a resolution in milliseconds.

import { resolutionToMs } from "@symmio/trading-core";
 
resolutionToMs("5m"); // 300_000
number
The nominal length in ms.

Throws UNKNOWN_CANDLE_RESOLUTION when given a code outside the vocabulary.

CANDLE_RESOLUTION_MS

The underlying table, Record<CandleResolution, number>.

1w and 1M are calendar units — a month is not a fixed span. The values here use nominal 7-day and 30-day lengths and are only ever used for request paging arithmetic (advancing a cursor past bars already received), never for aligning a bar to its boundary. Bars arrive already aligned by the venue.

Per-venue translation

Each venue integration ships its own mapping in and out of this vocabulary:
