EOD

FreeValueStandardPro

Fetch end-of-day interest rate history.

• Returns the interest rate reported. Depending on the rate, reports can occur in the morning or the afternoon.
• Valid symbol values per upstream RateType enum: SOFR, TREASURY_M1, TREASURY_M3, TREASURY_M6, TREASURY_Y1, TREASURY_Y2, TREASURY_Y3, TREASURY_Y5, TREASURY_Y7, TREASURY_Y10, TREASURY_Y20, TREASURY_Y30.

pub fn interest_rate_history_eod(
    &self,
    symbol: &str,
    start_date: &str,
    end_date: &str,
) -> InterestRateHistoryEodBuilder<'_>

Execute with .await → Result<Vec<InterestRateTick>, Error>, or decode chunk-by-chunk with .stream(handler).

Example

let rows = tdx.interest_rate_history_eod("SOFR", "20250303", "20250306").await?;
for t in &rows {
    println!("date={} rate={}", t.date, t.rate);
}

ThetaDataDxClient.interest_rate_history_eod(
    symbol, start_date, end_date,
    *,
    timeout_ms=None,
) -> InterestRateTickList

interest_rate_history_eod_async(...) awaits the same call shape. Chain .to_pandas() / .to_polars() / .to_arrow() / .to_list() on the result.

Example

rows = tdx.interest_rate_history_eod("SOFR", "20250303", "20250306")
for t in rows:
    print(t.date, t.rate)

interestRateHistoryEOD(
  symbol: string, startDate: string | Date, endDate: string | Date,
  options?: { ... },
): Promise<Array<InterestRateTick>>

Optional parameters ride in a single trailing options object: timeoutMs?: number.

Example

const rows = await tdx.interestRateHistoryEOD('SOFR', '20250303', '20250306');
for (const t of rows) {
  console.log(t.date, t.rate);
}

std::vector<InterestRateTick> interest_rate_history_eod(
    const std::string& symbol,
    const std::string& start_date,
    const std::string& end_date,
    const EndpointRequestOptions& options = {}) const;

Throws tdx::Error on failure.

Example

auto rows = client.interest_rate_history_eod("SOFR", "20250303", "20250306");
for (const auto& t : rows) {
    std::cout << t.date << ' ' << t.rate << "\n";
}
