OHLC

FreeValueStandardPro

Get the latest OHLC snapshot for one or more indices.

• Retrieves the real-time current day OHLC.
• Exchanges typically generate a price report every second for popular indices like SPX.

pub fn index_snapshot_ohlc(&self, symbols: &[&str]) -> IndexSnapshotOhlcBuilder<'_>

Optional parameters chain on the builder: .min_time(&str). Execute with .await → Result<Vec<OhlcTick>, Error>, or decode chunk-by-chunk with .stream(handler).

Example

let rows = tdx.index_snapshot_ohlc(&["SPX"]).await?;
for t in &rows {
    println!("date={} open={} high={} low={} close={}", t.date, t.open, t.high, t.low, t.close);
}

ThetaDataDxClient.index_snapshot_ohlc(
    symbols,
    *,
    min_time=None, timeout_ms=None,
) -> list[OhlcTick]

index_snapshot_ohlc_async(...) awaits the same call shape.

Example

rows = tdx.index_snapshot_ohlc(["SPX"])
for t in rows:
    print(t.date, t.open, t.high, t.low, t.close)

indexSnapshotOHLC(symbols: Array<string>, options?: { ... }): Promise<Array<OhlcTick>>

Optional parameters ride in a single trailing options object: minTime?: string | Date, timeoutMs?: number.

Example

const rows = await tdx.indexSnapshotOHLC(['SPX']);
for (const t of rows) {
  console.log(t.date, t.open, t.high, t.low, t.close);
}

std::vector<OhlcTick> index_snapshot_ohlc(
    const std::vector<std::string>& symbols,
    const EndpointRequestOptions& options = {}) const;

Optional parameters chain on EndpointRequestOptions: .with_min_time(...). Throws tdx::Error on failure.

Example

auto rows = client.index_snapshot_ohlc({"SPX"});
for (const auto& t : rows) {
    std::cout << t.date << ' ' << t.open << ' ' << t.high << ' ' << t.low << ' ' << t.close << "\n";
}
