bollingerbands(src, lkbk, mult, basis)
Bollinger Bands
Parameters:
src (float): float
lkbk (int): int
mult (float): float
basis (float)
Returns: Bollinger Bands
donchianchannels(src, lkbk, band_width)
Donchian Channels
Parameters:
src (float): float
lkbk (int): int
band_width (float): float

Removed:
doublehalfdonchianchannels(src, lkbk, divisor)
Double Half Donchian Channels
- just fixed a huge issue with the previous update from yesterday. so dumb, yet so obvious.
Hoping this works, otherwise I'll feel stupid republishing this library twice in the same day.
Range Channel, below, is designed to use any below chart indicator as a source. I wanted to be able to use the Keltner Channel as another band/channel in my below chart indicators that I will be updating shortly, but because it uses tr, atr, and range(price) it doesn't work with below chart indis. What this function aims to do is take the difference between the highest and lowest values on each below chart indicator "bar", apply a simple moving average to them, and then, like the Keltner Channel, add or subtract that value from a moving average, then multiply by some number.
Added:
rangechannel(src, mult, basis, width)
Range Channel
Parameters:
src (float): float
mult (float): float
basis (float): float
width (float): float
Returns: something like Keltner Channels but utilizing highest and lowest values of a below chart indicator instead of price values,
with an outer band of varying thickness adjustable by the width input
Removed:
rangechannel(src, period, mult, basis, width)
Range Channel
That didn't work. Looks like it's just Bollinger Bands, Donchian Channel, and Keltner Channel (which isn't useful on below-chart indicators).
