To compute the Commodity Channel Index (CCI) in Swift, you can follow these steps:

- Define variables for the typical price (TP), simple moving average (SMA), and mean deviation values.
- Calculate the typical price (TP) by averaging the high, low, and close prices for each period.
- Calculate the simple moving average (SMA) of the typical prices for the desired period.
- Calculate the mean deviation (MD) by taking the absolute difference between the typical price and the SMA and then averaging these values.
**Calculate the Commodity Channel Index (CCI) using the formula**: (TP - SMA) / (0.015 * MD)- Repeat steps 2-5 for each data point in your dataset to generate the CCI values for each period.

Here is a sample code snippet in Swift to compute the Commodity Channel Index (CCI):

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 |
let period = 20 // Desired period for CCI calculation func calculateCCI(data: [Double]) -> [Double] { var cciValues = [Double]() for i in period..<data.count { let tp = (data[i] + data[i - 1] + data[i - 2]) / 3.0 let sma = (data[i-period..<i].reduce(0, +)) / Double(period) let mdSum = data[i-period..<i].reduce(0) { result, value in result + abs(tp - value) } let md = mdSum / Double(period) let cci = (tp - sma) / (0.015 * md) cciValues.append(cci) } return cciValues } // Sample data let data = [100.0, 105.0, 110.0, 115.0, 120.0, 115.0, 110.0, 105.0, 100.0, 95.0, 90.0, 85.0, 80.0] let cciValues = calculateCCI(data: data) print(cciValues) |

This code snippet calculates the CCI values for a sample dataset of price values. You can adjust the `period`

variable to change the desired period for CCI calculation.
