MovingAveragesLibrary

٢٨ فبراير ٢٠٢٢

Library "MovingAveragesLibrary"
This is a library allowing one to select between many different Moving Average formulas to smooth out any float variable.

You can use this library to apply a Moving Average function to any series of data as long as your source is a float.

The default application would be for applying Moving Averages onto your chart. However, the scope of this library is beyond that. Any indicator or strategy you are building can benefit from this library.

You can apply different types of smoothing and moving average functions to your indicators, momentum oscillators, average true range calculations, support and resistance zones, envelope bands, channels, and anything you can think of to attempt to smooth out noise while finding a delicate balance against lag.

If you are developing an indicator, you can use the 'ave_func' to allow your users to select any Moving Average for any function or variable by creating an input string with the following structure:

var_name = input.string(<title>, <defval>, <options>)

Where the types of Moving Average you would like to be provided would be included in options.

Example:

i_ma_type = input.string(title = "Moving Average Type", defval = "Hull Moving Average", options = )

Where you would add after options the strings I have included for you at the top of the PineScript for your convenience.

Then for the output you desire, simply call 'ave_func' like so:

ma = ave_func(source, length, i_ma_type)

Now the plotted Moving Average will be the same as what you or your users select from the Input.
