DESCRIPTION
Pythagorean Means of Moving Averages

1. Calculates a set of moving averages for high, low, close, open and typical prices, each at multiple periods.
Period values follow the Fibonacci sequence.
The "short" set includes moving average having the following periods: 5, 8, 13, 21, 34, 55, 89, 144, 233, 377.
The "mid" set includes moving average having the following periods: 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597.
The "long" set includes moving average having the following periods: 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181.
2. User selects the type of moving average: SMA, EMA, HMA, RMA, WMA, VWMA.
3. Calculates the mean of each set of moving averages.
4. User selects the type of mean to be calculated: 1) arithmetic, 2) geometric, 3) harmonic, 4) quadratic, 5) cubic. Multiple mean calculations may be displayed simultaneously, allowing for comparison.
5. Plots the mean for high, low, close, open, and typical prices.
6. User selects which plots to display: 1) high and low prices, 2) close prices, 3) open prices, and/or 4) typical prices.
7. Calculates and plots a vertical deviation from an origin mean--the mean from which the deviation is measured.
8. Deviation = origin mean x a x b^(x/y)/c.
9. User selects the deviation origin mean: 1) high and low prices plot, 2) close prices plot, or 3) typical prices plot.
10. User defines deviation variables a, b, c, x and y.
Examples of deviation:
a) Percent of the mean = 1.414213562 = 2^(1/2) = Pythagoras's constant (default).
b) Percent of the mean = 0.7071067812 = [1/sqrt(2)] = [sqrt(2)/2] = sin 45˚ = cos 45˚.
11. Displaces the plots horizontally +/- by a user defined number of periods.

PURPOSE

1. Identify price trends and potential levels of support and resistance.

CREDITS

1. "Fibonacci Moving Average" by Sofien Kaabar: two plots, each an arithmetic mean of EMAs of 1) high prices and 2) low prices, with periods 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181.
2. "Solarized" color scheme by Ethan Schoonover.

發布通知

1) Added a list of mathematical constants to select as a deviation multiplier.
2) Edited script notes.

發布通知

1) updated script notes.
2) removed unrelated indicators from chart.

發布通知

1. Updated constants list.

發布通知

1. Added selection for period lengths based on either Fibonacci Numbers, Lucas Numbers, or Mersenne primes.

發布通知

Updated variable names.

發布通知

1. Added additional number sequences.

發布通知

Edited script: 1) moving averages periods, 2) new number sequences, 3) new constants.
Added script notes.

發布通知

1. Added option to calculate double and triple exponential moving averages. Moving average options include: SMA, EMA, DEMA, TEMA, RMA, WMA, VWMA.
2. Chart displayed shows the cubic mean of EMAs having period length values equal to Mersenne prime exponents (3, 5, 7, 13, 17, 19, 31, 61, 89, 107, 127, 521, 607, 1279, 2203).

發布通知

Added some flexibility in how the plots can be adjusted:
1. increase all moving averages' periods by a specified number of periods.
2. apply the above to high prices or low prices, open prices or close prices, or typical prices.
3. added the OEIS reference number next to the number sequence names within the script notes.

發布通知

1. Added more number sequences: Pell, Padovan, Perrin, Catalan, Narayana.
2. Added more moving averages: Triple-EMA (TEMA), Quadruple-EMA (QEMA), Quintuple-EMA (PEMA).

Note: TEMA, QEMA, and PEMA may not display when used with "long" or "mid" lookback periods with some number sequences. If TEMA, QEMA, or PEMA do not display, select a shorter lookback period, e.g., "mid" or "short", or a number sequence having fewer periods included within the current lookback selection.

發布通知

1. Added the option to displace plots horizontally: 1) plots and deviations generated from Open, High, Low, and Close prices separately from 2) plots generated from Typical Prices.
2. Added the Jacobsthal number sequence.

發布通知

Added options to plot 2 reference moving averages and displace these +/- horizontally by a specified number of periods.

發布通知

1. Added option to choose Zero Lag Exponential Moving Averages. The selected moving average type is what is used in mean calculations.
2. Fixed error in mean equation script notes. Plotted mean was correct. Notes were incorrect, now corrected.
3. Change optional defaults as follows: Cubic mean of EMAs, with EMA periods equal to the Lucas Numbers. (Lucas numbers are related to Fibonacci numbers in that their ratio is also equal to the Golden Ratio.) Offset from mean of typical price (High + Low + Close) / 3 EMAs equal to 3x the Golden Ratio. Mean of typical prices is shifted forward 29 periods. Optional reference moving averages displayed are 50 and 250 EMA.
