Keltner Channels show a central moving average of the typical price line plus channel lines at a distance above and below. This distance is the simple moving average of the past 10 days' trading ranges. The strategy is to regard a close above the upper line as a strong bullish signal and a close below the lower line as strong bearish signal.
Bear power subtracts an exponential moving average from the corresponding low price of that trading day.Bear Power represents the ability of the bears to push prices below the average consensus of value.
Bull Power represents the ability of the bulls to raise prices above the average consensus of value.
Uses an exponential moving average, which is a trend-following indicator essential to the calculation. Bull power is a simple calculation, derived by subtracting an exponential moving average of closing prices from a high price.
Displays one of the following Moving average types according to Ma Type input
1 Simple moving average
2 Exponential moving average
3 Smoothed moving average
4 Linear weighted moving average
5 Double Exponential Moving Average
6 Triple Exponential Moving Average
7 T3 Moving Average
Average True Range Channels are calculated by adding and subtracting a weighted Average True Range to a Moving Average usually simple.
When the ATR is added it produces the Upper Band.
When subtracted the Lower Band.
In this case there are 3 sets of channels each with an upper and lower band.
Wilder’s Smoothing AKA Smoothed Moving Average
The first value is a simple moving average and all subsequent values are
calculated based on the previous value according to the following formula:
SUM(1) = SUM(CLOSE, N)
WSMA(1) = Simple MA = SUM(1)/N - Wilder’s Smoothing for the first period.
WSMA(i) = (SUM(i - 1) - WSMA(i - 1) + CLOSE(i)) / N
This indicator uses a weighted sum of: single EMA, double EMA, triple EMA etc. For this reason, unlike the regular MA, T3MA is a very smooth line. This indicator uses the following formula:
T3MA = c1*e6 + c2*e5 + c3*e4 + c4*e3
e1 = EMA (CLOSE, Period) e2 = EMA (e1, Period) e3 = EMA (e2, Period) e4 = EMA (e3, Period) e5 = EMA (e4, Period) e6 = EMA (e5, Period) c1 = - b3 c2 = 3*b2 + 3*b3 c3 = - 6*b2 - 3*b - 3*b3 c4 = 1 + 3*b + b3 + 3*b2 (EMA = Exponential Moving Average, b = volume factor (default = 0.7))
