Historical Prices
Historical OHLCV bars for one symbol at one resolution, returned as compact [ts_ms, adjClose] tuples for efficient charting. The latest bar's full OHLCV detail is also included.
Resolutions: 1d (default), 1wk, 1mo.
History depth per plan: Free = last 2 years, Starter = last 5 years, Stock / ETF / Pro = 20 years.
Delisted listings are not served. A ticker identifies an instrument only while its listing is active; once delisted the symbol may be reassigned to another registrant, so a selector resolving to a delisted listing returns 400 rather than another company's prices.
