TA.EMA

The TA.EMA() function is used to calculate the exponential average indicator.

The return value of the TA.EMA() function is: a one-dimensional array. array

TA.EMA(inReal) TA.EMA(inReal, optInTimePeriod)

The inReal parameter is used to specify the K-line data. inReal true {@struct/Record Record} structure arrays, numeric arrays The optInTimePeriod parameter is used to set the period. optInTimePeriod false number

function main(){
    var records = exchange.GetRecords()
    // Determine if the number of K-line bars meets the calculation period of the indicator
    if (records && records.length > 9) {
        var ema = TA.EMA(records, 9)          
        Log(ema)
    }
}

def main():
    r = exchange.GetRecords()
    if r and len(r) > 9:
        ema = TA.EMA(r, 9)
        Log(ema)

void main() {
    auto r = exchange.GetRecords();
    if(r.Valid && r.size() > 9) {
        auto ema = TA.EMA(r, 9);
        Log(ema);
    }
}

The default value of the optInTimePeriod parameter of the TA.EMA() function is: 9.
