Accumulation Distribution Index of specified length for timeseries of OHLCV

CLV ranges from -1.0 when the close is the low of the day, to +1.0 when it’s the high. For instance if the close is 3/4 the way up the range then CLV is +0.5. The accumulation/distribution index adds up volume multiplied by the CLV factor, i.e.

ADI = ADI_prev + CLV * volume

The name accumulation/distribution comes from the idea that during accumulation buyers are in control and the price will be bid up through the day, or will make a recovery if sold down, in either case more often finishing near the day’s high than the low. The opposite applies during distribution.

The accumulation/distribution index is similar to on balance volume, but acc/dist is based on the close within the day’s range, instead of the close-to-close up or down that the latter uses.

Can be used by a shortcut ADI

Used in indicators: Chaikin Money Flow, Chaikin Oscillator

§Parameters

Has a single parameter length: PeriodType

When length == 0, ADI becomes windowless. That means full ADI value accumulation over time.

When length > 0, ADI will be calculated over the last length values.

§Input type

Input type is reference to OHLCV

§Output type

Output type is ValueType

§Examples

use yata::prelude::*;
use yata::methods::ADI;
use yata::helpers::RandomCandles;

let mut candles = RandomCandles::default();
let mut windowless = ADI::new(0, &candles.first()).unwrap();
let mut windowed = ADI::new(3, &candles.first()).unwrap(); // <----- Window size 3

let candle = candles.next().unwrap();
assert_ne!(windowless.next(&candle), windowed.next(&candle));

let candle = candles.next().unwrap();
assert_ne!(windowless.next(&candle), windowed.next(&candle));

let candle = candles.next().unwrap();
assert!((windowless.next(&candle)-windowed.next(&candle)).abs() < 1e-5); // Must be equal here

§Performance

O(1)
