Money Flow Index (MFI)
Money Flow Index is an oscillator indicator that is used to measure buying and selling pressure by utilizing both price and volume.
- Sources:
- Calculation:
- Default Inputs:
length=14, drift=1
tp = typical_price = hlc3 = (high + low + close) / 3 rmf = raw_money_flow = tp * volume
pmf = pos_money_flow = SUM(rmf, length) if tp.diff(drift) > 0 else 0 nmf = neg_money_flow = SUM(rmf, length) if tp.diff(drift) < 0 else 0
MFR = money_flow_ratio = pmf / nmf MFI = money_flow_index = 100 * pmf / (pmf + nmf)
- Args:
high (pd.Series): Series of ‘high’s low (pd.Series): Series of ‘low’s close (pd.Series): Series of ‘close’s volume (pd.Series): Series of ‘volume’s length (int): The sum period. Default: 14 talib (bool): If TA Lib is installed and talib is True, Returns the TA Lib
version. Default: True
drift (int): The difference period. Default: 1 offset (int): How many periods to offset the result. Default: 0
- Kwargs:
fillna (value, optional): pd.DataFrame.fillna(value) fill_method (value, optional): Type of fill method
- Returns:
pd.Series: New feature generated.
