go-chaikin

The Chaikin Oscillator technical analysis algorithm implemented in Golang.

import "github.com/MicahParks/go-chaikin"

Usage

For full examples, please see the examples directory.

Step 1

Gather the initial input. This is 10 periods of inputs for the Accumulation Distribution Line. It is the minimum number of periods required to produce one result for the Chaikin Oscillator. The value, 10 is stored in chaikin.LongEMA constant.

The input must be put into an array, not a slice. Make sure to fill all 10 indices of the array.

initial := [chaikin.LongEMA]ad.Input{}
for i := 0; i < chaikin.LongEMA; i++ {
	initial[i] = ad.Input{
		Close:  closePrices[i],
		Low:    low[i],
		High:   high[i],
		Volume: volume[i],
	}
}

Step 2

Create the Chaikin Oscillator data structure from the initial input array. This will also produce the first Chaikin Oscillator point as well as its corresponding Accumulation Distribution Line point.

cha, firstResult, adLine := chaikin.New(initial)

Step 3

Use the subsequent periods to calculate the next points for the Chaikin Oscillator and Accumulation Distribution Line.

result, adLine = cha.Calculate(ad.Input{
	Close:  closePrices[i],
	Low:    low[i],
	High:   high[i],
	Volume: volume[i],
})

Somewhat complete example (without data)

package main

import (
	"log"
	"os"

	"github.com/MicahParks/go-ad"

	"github.com/MicahParks/go-chaikin"
)

func main() {
	// Create a logger.
	logger := log.New(os.Stdout, "", 0)

	// Create the initial input.
	initial := [chaikin.LongEMA]ad.Input{}
	for i := 0; i < chaikin.LongEMA; i++ {
		initial[i] = ad.Input{
			Close:  closePrices[i],
			Low:    low[i],
			High:   high[i],
			Volume: volume[i],
		}
	}

	// Create the Chaikin Oscillator data structure as well as its first data point and the corresponding Accumulation
	// Distribution Line point.
	cha, result, adLine := chaikin.New(initial)
	logger.Printf("%.4f, %.4f", adLine, result)

	// Use every subsequent period's data to calculate the next points on the Chaikin Oscillator and Accumulation
	// Distribution Line.
	for i := range open[chaikin.LongEMA:] {
		i += chaikin.LongEMA

		result, adLine = cha.Calculate(ad.Input{
			Close:  closePrices[i],
			Low:    low[i],
			High:   high[i],
			Volume: volume[i],
		})
		logger.Printf("%.4f, %.4f", adLine, result)
	}
}
