Papercuts Dynamic EMA - Relative Parameter FunctionThe goal of this is to link two parameters of different known low and high values so one affects the other.
In this case, I want to link Relative Volume to the length of an EMA, so it responds faster in times of high volume.
As an animator I am used to linking values in this way with Maya using a set driven key, took some work to figure it out in pine.
Looking up this concept, it has a few names, Relative values, linear interpolation, or rescale values.
Thanks to pinecoders for writing the EMA funciton that can accept length variables!
Here's a quick look at the root function to link the two values.
f_relativeVal(_source, in_bot, in_top, out_bot, out_top) =>
// float _source: input signal
// float in_bot : minimum range of input signal.
// float in_top : maximum range of input signal.
// float out_bot : minimum range of output signal.
// float out_top : maximum range of output signal.
clampSrc = _source > in_top ? in_top : _source < in_bot ? in_bot : _source //claps source to create a controlled range
//relInput = (clampSrc - in_bot) / (in_top - in_bot) * 100
inDiffIncrement = (in_top - in_bot)
outDiffIncrement = (out_top - out_bot)
out_bot + (clampSrc - in_bot) * outDiffIncrement / inDiffIncrement // rescale input range to output range

Moving Average Ribbon [TheBearFighter]
This code was written using:
•Pine Script Coding Conventions.
This script provides a very useful tool for new community users and professionals. It puts at your disposal a Moving Average Ribbon by hand to graph and easily find the ones with the highest performance. The creation of this script was motivated because in free PulseWire accounts there is a limit of 3 indicators by chart, and with this tool you can draw up to 32 MA's at the same time!
Choose one of 10 types of MA´s:
•KAMA Kaufman's moving average.
•HULL Hull moving average.
•TEMA Triple exponencial moving average.
•LSMA Least square moving average.
•DEMA Double exponencial moving average.
•ALMA Arnaud Legoux moving average.
•WMA Weighted moving average
•EMA Exponencial moving average.
•VWMA Volume Weighted moving average.
•SMA Simple moving average.
Use the tooltips to know the lengths of MA´s.
A main characteristic of the script is that the lengths are in days but when changing the lowest timeframes, the same daily resolution is maintained. This gives us extreme precision in intraday timeframes, e.g 30 minutes.
Once this is understood, we can turning the MA´s on/off, and changing the timeframe to our liking.
Available timeframes: M, W, D, 4H, 1H, 30m, 15m, 5m.
Also the MA´s are colored for easy visualization and know if they grow or decrease.
Thank´s to @midtownsk8rguy to let me know more about HEX colors.
Thank´s to @HPotter for his KAMA.

Supertrend BandsSupertrend Bands
What is the Supertrend indicator?
"The Supertrend indicator is a trend following overlay on your trading chart, much like a moving average, that shows you the current trend direction.
The indicator works well in a trending market but can give false signals when a market is trading in a range.
It uses the ATR (average true range) as part of its calculation which takes into account the volatility of the market. The ATR is adjusted using the multiplier setting which determines how sensitive the indicator is."
"For the basic Supertrend settings, you can adjust period and factor:
- The period setting is the lookback for the ATR calculation
- Factor is the what the ATR is multiplied by to offset the bands from price"
How to use this indicator
This indicator is inspired by a strategy I found. It includes four Supertrend indicators, each with different settings that displays trend strength and support/resistance zones. The default settings are optimal for cryptocurrency but do work quite well for traditional also. I highly recommend you try experimenting with different settings, increasing them to suit the instrument.
The bands are set from low to high, Band 1 being the fastest and Band 4 being the slowest. Band 4 is the one that sets the overall trend so when price is above Band 4, the trend is bullish and vice versa. Trend is strongest when price is above/below Band 1 and gets weaker as it filters through each band. Band 4 provides the strongest support/resistance and if that breaks the trend flips.
In the menu, you will see an option called "Remove Anti Trend?". It is enabled by default and it removes any bearish/resistance bands when the trend is up and any bullish/support bands when the trend is down. When turned off, it will show all Supertrend Bands as they are by default.
Bar Colors
Bar colors are optional and they reflect the current trend strength based on the Supertrend bands.
Alternate ways of using this indicator
You could leave everything as default or you can display individual bands. For instance, because I use many overlay indicators, most of the time I turn off all the bands and only show bar colors:
You can also turn off Bands 1 and 2 and only show the two slowest lengths:
This removes the noise of the two faster Supertrends.
Or just show the two fastest bands:
Any suggestions to improve this indicator are most welcome :) Indicator
