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:
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.

I'm not too familiar with your specific use case, and unfortunately can't offer any advice off the top of my head. Can you share the operation you're trying to pull off and I can give you my thoughts? (ie: share the code line)

@CrackingCryptocurrency, Hey! Thanks for the reply. Actually, I figured it out. I just had an error in my code that was causing it not to work as expected. I was just referring to the standard historical brackets to go back x number of bars for the data you need. Your library works fine, I was just doing it wrong. HAHA. Thanks again! I use this library in all of my indicators/studies. I'm mostly just building to learn how the market moves right now, and plan to get into more elaborate uses down the road.

Thank you for this. Especially the universal Smoothing Function. Makes things a LOT easier. Surprised no other libraries have this. Either way....WAY TO GO!!!
Quick question though, is there no way to use the historical operator with these? I'm trying to pull old values on the smma.
