Struct ta::indicators::MoneyFlowIndex

pub struct MoneyFlowIndex { /* fields omitted */ }

Money Flow Index (MFI).

The MFI is an volume and price based oscillator which gives moneyflow over n periods. MFI is used to measure buying and selling pressure. MFI is also known as volume-weighted RSI.

Formula

Typical Price(TP) = (High + Low + Close)/3

Money Flow(MF) = Typical Price x Volume

MF is positive when currennt TP is greater that previous period TP and negative when current TP is less than preivous TP.

Positive money flow (PMF)- calculated by adding the money flow of all the days RMF is positive.

Negative money flow (NMF)- calculated by adding the money flow of all the days RMF is negative.

Money Flow Index(MFI) = PMF / (PMF + NMF) * 100

Parameters

• period - number of periods, integer greater than 0

Example

use ta::indicators::MoneyFlowIndex;
use ta::{Next, DataItem};

let mut mfi = MoneyFlowIndex::new(3).unwrap();
let di = DataItem::builder()
            .high(3.0)
            .low(1.0)
            .close(2.0)
            .open(1.5)
            .volume(1000.0)
            .build().unwrap();
mfi.next(&di);
