imp_volatility ( String priceType );
Default values:
priceType: "<current type>"
Description
Returns the implied volatility for the specific symbol, aggregation period and price type. You can use both Aggregation Period constants and pre-defined string values (e.g. Day, 2 Days, Week, Month, etc.) as valid parameters for the aggregation period. The full list of the pre-defined string values can be found in the Referencing Secondary Aggregation article.
Valid parameters for the price type are: LAST, ASK, BID, and MARK. Alternatively, you can use the PriceType constants.
Note that for non-Forex symbols, the last three are only supported on intraday charts with time interval not greater than 15 days.
