talib.STOCHF(inPriceHLC, optInFastK_Period)


    
    
    
talib.STOCHF(inPriceHLC, optInFastK_Period, optInFastD_Period)


    
    
    
talib.STOCHF(inPriceHLC, optInFastK_Period, optInFastD_Period, optInFastD_MAType)

Examples

Compute the Stochastic Fast from the latest K-lines.

    javascript
    
    
function main() {
    var records = exchange.GetRecords()
    if (!records) return
    var ret = talib.STOCHF(records)

Returns

Type	Description
array	Two-dimensional array: [fast %K array, fast %D array] (a tuple in the same order in Python).

Arguments

Name	Type	Required	Description
inPriceHLC	`Record` array	Yes	K-line array; the high, low and close fields are used. In Python, pass `records.High`, `records.Low`, `records.Close` in this order.
optInFastK_Period	number	No	Fast %K period. Default `5`.
optInFastD_Period	number	No	Fast %D period. Default `3`.
optInFastD_MAType	number	No	Moving average type of fast %D; see the MAType table on the `Talib` page. Default `0` (SMA).
