    val cciValues = mutableListOf<Double>()

    for (i in period until prices.size) {
        val tp = prices.subList(i - period, i).sum() / period // Typical Price calculation
        val meanDeviation = prices.subList(i - period, i).map { Math.abs(it - tp) }.sum() / period // Mean Deviation calculation

        val cci = (tp - prices[i]) / (0.015 * meanDeviation) // CCI calculation
        cciValues.add(cci)
    }

    return cciValues
}

fun main() {
    val prices = listOf(10.0, 12.0, 14.0, 16.0, 18.0, 20.0, 22.0) // Sample prices data
    val period = 4 // CCI period

    val cciValues = calculateCCI(prices, period)
    println("CCI values: $cciValues")
}
