Synchronize Local quantmod OHLC Data

Description

Synchronize Local quantmod OHLC Data

Usage

sync_local_quantmod_OHLC(
  ticker,
  label = ticker,
  from,
  to,
  src = "yahoo",
  local_path = NULL,
  max_attempts = 3L,
  retry_delay_seconds = 1,
  fallback_source = NULL,
  fallback_ticker = ticker
)

Arguments

ticker	Market symbol passed to quantmod::getSymbols().
label	Optional label to store in the standardized symbol column.
from	Start date.
to	End date.
src	quantmod source, default "yahoo".
local_path	Optional local storage path.
max_attempts	Maximum bounded attempts for a transient source failure.
retry_delay_seconds	Initial retry delay in seconds; delays use exponential backoff.
fallback_source	Optional explicitly configured fallback provider. Currently supports "eastmoney" for daily OHLC data. For Yahoo sources, a failed dated quantmod request first retries Yahoo's chart endpoint with a bounded range before this external fallback is considered.
fallback_ticker	Optional provider-specific fallback identifier.

Details

An external fallback never replaces a finite existing primary-source OHLC bar. It only fills keys whose local bars are missing or invalid.

Value

A sync result list.
