MAMA (MESA Adaptive Moving Average)

Indicator Description

MAMA (MESA Adaptive Moving Average) is an adaptive moving average that automatically adjusts its smoothing level according to market volatility, providing both fast and slow moving averages.

Function Information

• Function Name: MAMA
• Input Parameters:
  • #Kline: K-line data
• Parameter Settings:
  • fastlimit: Fast limit (default: 0.5)
  • slowlimit: Slow limit (default: 0.05)
• Output:
  • mama: Adaptive moving average
  • fama: Fast adaptive moving average

Calculation Principle

MAMA is calculated using the following formula:

alpha = 2 * (fastlimit - slowlimit) / (1 + fastlimit)
mama = alpha * price + (1 - alpha) * mama[1]
fama = 0.5 * alpha * mama + (1 - 0.5 * alpha) * fama[1]

Where:

• alpha is the adaptive coefficient
• price is the current price
• mama[1] is the MAMA value of the previous period
• fama[1] is the FAMA value of the previous period
