Code Example

Rust

let data = tdx.index_history_ohlc("SPX", "20260101", "20260301", "60000").await?;
for t in &data {
    println!("date={} ms_of_day={} open={:.2} high={:.2} low={:.2} close={:.2}",
        t.date, t.ms_of_day, t.open, t.high, t.low, t.close);
}

Python

data = tdx.index_history_ohlc("SPX", "20260101", "20260301", "60000")
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}")

TypeScript

const data = tdx.indexHistoryOHLC('SPX', '20260101', '20260301', '60000');
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++

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

SPX 1-minute OHLC bars. Requires Standard subscription.

Notes

• Shorthand is supported: "1m", "5m", "15m", "1h". Milliseconds ("60000", "300000", "900000", "3600000") are auto-converted to the nearest valid preset.
• Use start_time and end_time to filter to regular trading hours only (e.g. "34200000" to "57600000" for 9:30 AM to 4:00 PM ET).
• For end-of-day data only, use index_history_eod instead.
