index_snapshot_ohlc

FreeValueStandardPro

Get the latest OHLC (open, high, low, close) snapshot for one or more index symbols. Returns the most recent bar data.

Code Example

Rust

let data = tdx.index_snapshot_ohlc(&["SPX", "VIX"]).await?;
for t in &data {
    println!("date={} ms_of_day={} open={:.2} high={:.2} low={:.2} close={:.2} volume={}",
        t.date, t.ms_of_day, t.open, t.high, t.low, t.close, t.volume);
}

Python

data = tdx.index_snapshot_ohlc(["SPX", "VIX"])
for t in data:
    print(f"date={t.date} ms_of_day={t.ms_of_day} open={t.open:.2f} "
          f"high={t.high:.2f} low={t.low:.2f} close={t.close:.2f} volume={t.volume}")

TypeScript

const data = tdx.indexSnapshotOhlc(['SPX', 'VIX']);
for (const t of data) {
    console.log(`date=${t.date} ms_of_day=${t.ms_of_day} open=${t.open} high=${t.high} low=${t.low} close=${t.close}`);
}

C++

auto data = client.index_snapshot_ohlc({"SPX", "VIX"});
for (const auto& t : data) {
    printf("date=%d ms_of_day=%d open=%.2f high=%.2f low=%.2f close=%.2f volume=%d\n",
        t.date, t.ms_of_day, t.open, t.high, t.low, t.close, t.volume);
}

OHLC snapshot for SPX and NDX. Indices do not have volume data.

Notes

• Pass multiple symbols in a single call to batch requests efficiently.
• During market hours, the snapshot reflects the current partial bar.
