Kaufman's Adaptive Moving Average (KAMA) - Multi timeframe

Kaufman's Adaptive Moving Average (KAMA)
KAMA was developed by Perry Kaufman to give better directions of short term market trends.

Idea is similar to an EMA, but it makes adjustments to the smoothing factor by taking Market Noise into consideration. Levels of noise in KAMA is modelled using Kaufman's Efficiency Ratio.

The problem with traditional of moving averages (ie. SMA/EMA) is that they are very sensitive to sudden price movements.

Applications:
- Less prone to false signals compared to other types of moving averages. When price suddenly surges or tanks, KAMA will lag behind telling us that the move is rather abnormal.
- On the other hand, when volatility of price movements is low, KAMA will be close to the ranging candles with a slope approximate to zero. KAMA can be used for filtering out choppy markets.

Other features:
- Multi-timeframe.
- Can visualize levels of market noise with background color mode turned on.
