Bollinger Bands contain three lines: a moving average, an upper band and a lower band. The upper band equals K times a standard deviation above the moving average and the lower band K times a standard deviation below the moving average. The standard deviation uses the same period as the moving average.

Historical volatility, as the name implies, measures the volatility of a market in the past, i.e. the historical fluctuation of price.  As such it uses historical price data for the calculation. The calculation of volatility is the standard deviation of the natural logarithmic price change.  

The PRC indicator applies a polynomial function to the linear regression function to adapt itself to the flow of market prices. Since they are regression bands that self adjust for volatility.

  The Keltner Channel is a moving average band indicator whose upper and lower bands adapt to changes in volatility by using the average true range.

This indicator uses polynomial regression to calculate first the center of gravity of a moving price and 3 standard deviations to upwards (red stripes) and 3 down (green stripes).  

IFRAMA stands for Fractal Adaptive Moving Average and is another stroke of genius from John F Ehlers. It utilizes Fractal Geometry in an attempt to dynamically adjust its smoothing period to suit the changing price action over time.

This is a rework of the PRC by A T. I just added some features to make backtesting easier with this indicator, now you can use ctrl to move the channel, and shift to set its lenght. try it, you won't be disappointed   Changelog 1 - Added the extension feature! Now you can extend the channel beyond its ending point to create pivots that can be a useful substitution for fibonacci and the classic pivots; this method can be applied to swings to see their volatility projection. Changelog 2 - Now if you scroll past the right end of the channel while holding shift you can adjust the projection lenght Changelog 3 - Added trend projection! Now you can switch between static and trending volatility projections by pressing ctrl + alt + left click. Also, the degree of the projection can be changeg by using ctrl + click and alt + click!  

A measure of volatility for the currency pair. The average daily range is the average of the daily range (High - Low) over a given number of days. It can be calculated over different periods.  

Last update: Added: correlation pairs & editable some interfaces  This indicator is used for checking all major currencies strength after comparing them with each other How it works: I. Sum of [(high - low) + Abs(open - close)] in the last [input peroids] II. Average them with one of these (Simple Moving Average, Weighted Moving Average, Exponential Moving Average or use Average True Range instead) III. Compare each of them with each other, then convert it to the percentage Let me know if there's any bug or feedback Cheers
