talib.ACCBANDS

Calculates the Acceleration Bands and returns the upper band, middle band and lower band.

    
    
    
talib.ACCBANDS(inPriceHLC)

    
    
    
talib.ACCBANDS(inPriceHLC, optInTimePeriod)

Examples

Compute the Acceleration Bands from the latest K-lines.

    javascript
    
    
function main() {
    var records = exchange.GetRecords()
    if (!records) return
    var ret = talib.ACCBANDS(records)
    // Output: [upper band array, middle band array, lower band array]
    Log(ret)
}

    python
    
    
import talib
def main():
    records = exchange.GetRecords()
    if not records:
        return
    upper, middle, lower = talib.ACCBANDS(records.High, records.Low, records.Close)
    # Output: (upper band array, middle band array, lower band array)
    Log(upper, middle, lower)

Remarks

TA-Lib equivalent: ACCBANDS(Records[High,Low,Close],Time Period = 20) = [Array(outRealUpperBand),Array(outRealMiddleBand),Array(outRealLowerBand)].

The upper band is the simple moving average of High * (1 + 4 * (High - Low) / (High + Low)), the middle band is the simple moving average of the close price, and the lower band is the simple moving average of Low * (1 - 4 * (High - Low) / (High + Low)), all over optInTimePeriod bars.

In Python, TA-Lib provides this function from version 0.6 (both the C library and the Python package must be 0.6 or later); older versions raise an attribute error.
