[−][src]Struct ta::indicators::MoneyFlowIndex
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
- n - 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);
