A context for producing valuations over multiple dates

Parameters:

  • start (Union[int, date, None]) – start date

  • end (Union[int, date, None]) – end date (defaults to today)

  • calendars (Union[str, Tuple]) – holiday calendars

  • dates (Optional[Iterable[date]]) – a custom iterable of dates

  • is_async (Optional[bool]) – return immediately (True) or wait for results (False) (defaults to False)

  • is_batch (Optional[bool]) – use for calculations expected to run longer than 3 mins, to avoid timeouts. It can be used with is_async=True|False (defaults to False)

  • use_cache (Optional[bool]) – store results in the pricing cache (defaults to False)

  • visible_to_gs (Optional[bool]) – are the contents of risk requests visible to GS (defaults to False)

  • csa_term (Optional[str]) – the csa under which the calculations are made. Default is local ccy ois index

  • market_data_location (Optional[str]) – the location for sourcing market data (‘NYC’, ‘LDN’ or ‘HKG’ (defaults to LDN)

  • timeout (Optional[int]) – the timeout for batch operations

  • show_progress (Optional[bool]) – add a progress bar (tqdm)

  • use_server_cache (Optional[bool]) – cache query results on the GS servers

Examples

>>> from gs_quant.instrument import IRSwap
>>>
>>> ir_swap = IRSwap('Pay', '10y', 'DKK')
>>> with HistoricalPricingContext(10):
>>>     price_f = ir_swap.price()
>>>
>>> price_series = price_f.result()
