- Calculation:
- Default Inputs:
length=7, multiplier=3.0
- Default Direction:
Set to +1 or bullish trend at start
MID = multiplier * ATR LOWERBAND = HL2 - MID UPPERBAND = HL2 + MID
- if UPPERBAND[i] < FINAL_UPPERBAND[i-1] and close[i-1] > FINAL_UPPERBAND[i-1]:
FINAL_UPPERBAND[i] = UPPERBAND[i]
- else:
FINAL_UPPERBAND[i] = FINAL_UPPERBAND[i-1])
- if LOWERBAND[i] > FINAL_LOWERBAND[i-1] and close[i-1] < FINAL_LOWERBAND[i-1]:
FINAL_LOWERBAND[i] = LOWERBAND[i]
- else:
FINAL_LOWERBAND[i] = FINAL_LOWERBAND[i-1])
- if close[i] <= FINAL_UPPERBAND[i]:
SUPERTREND[i] = FINAL_UPPERBAND[i]
- else:
SUPERTREND[i] = FINAL_LOWERBAND[i]
- Args:
high (pd.Series): Series of ‘high’s low (pd.Series): Series of ‘low’s close (pd.Series): Series of ‘close’s length (int) : length for ATR calculation. Default: 7 multiplier (float): Coefficient for upper and lower band distance to
midrange. Default: 3.0
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.DataFrame: SUPERT (trend), SUPERTd (direction), SUPERTl (long), SUPERTs (short) columns.
