updateMarketHoliday

Syntax

updateMarketHoliday(marketName, holiday)

Arguments

marketName is a STRING scalar, indicating the identifier of the trading calendar, e.g., the Market Identifier Code of an exchange, or a user-defined calendar name.

holiday is a vector of DATE type, indicating weekday holidays.

Details

Updates the holiday calendar named marketName in memory online and synchronizes updates to the file in marketHolidayDir. If the file does not exist in memory, an error will be reported.

Note:

  • It can only be executed by an administrator.

  • It only takes effect on the current node. In a cluster, pnodeRun can be used to call this function on all data/compute nodes.

  • If you have manually modified the trading calendar under marketHolidayDir and want to synchronize updates to memory without restarting the server, you can use function loadText to load the updated CSV file to an in-memory table and convert it to a vector (holiday), then update the holiday to memory by updateMarketHoliday.

Examples

$ addMarketHoliday("CFFEX",2022.01.03 2022.01.05)
$ temporalAdd(2022.01.01,1,"CFFEX")
2022.01.04
$ index = [2022.01.01, 2022.01.02, 2022.01.03, 2022.01.04]
$ s = indexedSeries(index, 1..4)
$ s.resample("CFFEX", sum);
