@diazlaz was kind enough to help me port this version of ATR Percentile Rank from TradingView over to ThinkorSwim. I thought it was interesting.

CM ATR PercentileRank - Great For Showing Market Bottoms.

When Increased Volatility to the Downside Reaches Extreme Levels it’s Usually a Sign of a Market Bottom.

This Indicator Takes the ATR and uses a different LookBack Period to calculate the Percentile Rank of ATR Which is a Great Way To Calculate Volatility

Be Careful Of Using w/ Market Tops. Not As Reliable.


***Ability to Control ATR Period and set PercentileRank to Different Lookback Period

***Ability to Plot Histogram Just Showing Percentiles or Histogram Based on Up/Down Close

Fuchsia Lines = Greater Than 90th Percentile of Volatility based on ATR and LookBack Period.
Red Lines = Warning — 80-90th Percentile
Orange Lines = 70-80th Percentile

For this ToS version:
  • Magenta = Greater than 90th Percentile
  • Orange = 70-80th
  • Red = 80-90

This looks promising. I will definitely test it out.
It would be nice to have an intraday study version that adjusts automatically. Just like the volume profile for ORB indicator.

@BenTen, I see thanks. Where on the script can i rem out the coloring on the candlesticks? I ask because the screenshot you have here is exactly what i was expecting but the current script colors all the candlestick

@BenTen if possible, can you please consider updating the code to support the colored bars on mobile? right now they're either green or red indicating up/down moves, would really appreciate it! thanks.

Hey all - just found this awesome community. I'm a new thinkorswim user coming from Amibroker. One indicator or calculation I'm missing (or having found yet in ToS) is PercentRank. It's built into a variety of platforms (TradingView, Amibroker, Tradestation, etc.). Amibroker describes it as such:

Code:
PercentRank( array, range )

INPUTS:
array - input data
range - lookback range
Returns percent rank (0...100) of the current element of the array within all elements over the specified range.

A value of 100 indicates that the current element of the array is the highest for the given lookback range, while a value of 0 indicates that the current value is the lowest for the given lookback range.

It is equivalent (but 2x faster) to:

function PercentRank2( Data, Periods)
{
   Count = 0;
  for ( i = 1; i <= Periods ; i++ )
   {
   Count += Data > Ref( Data, -i );
   }
  return 100 * Count / Periods;
}

Does this exist in ToS and I just haven't found it or would it require custom coding?

Any help greatly appreciated!

Droskill, were you ever able to figure this out? It is exactly what I am looking for as well for ToS.

I love this ATR Percentile Rank Indicator and would love to do something similar for both OBV and Implied Volatility. I tried tweaking the script and referencing those studies, but wasn't quite sure how to define OBV for this. Any help is greatly appreciated!

I think I finally figured it out!! Here is what I have so far for those interested. This Indicator Takes OnBalanceVolume and uses a different LookBack Period to calculate the Percentile Rank of OBV. Feel free to adjust, correct, or improve. I am still fairly new at ThinkScript.

Code:
#OBV_Percentile for ThinkorSwim Version 1.0
#
#VERSION
# 2021.02.17 V1.0
#This Indicator Takes OnBalanceVolume and uses a different LookBack Period
#to calculate the Percentile Rank of OBV
#

declare lower;

#INPUTS
input price = close;
input averageType = AverageType.WILDERS;

#LOGIC

#//OBV PercentileRank Calculations

def vol = OnBalanceVolume();
input TimePeriod = 252;

def data = if !IsNaN(vol) then vol else vol[-1];
def hi = Highest(data, TimePeriod);
def lo = Lowest(data, TimePeriod);
plot Percentile = (data - lo) / (hi - lo) * 100;
def lowend = Percentile < 25;
def highend = Percentile > 50;

input over_Bought1 = 98;
input over_Sold1 = 2;

Percentile.DefineColor("HighVolume", Color.RED);
Percentile.DefineColor("Normal", Color.YELLOW);
Percentile.DefineColor("LowVolume", Color.GREEN);
Percentile.AssignValueColor(if Percentile > over_Bought1 then Percentile.Color("HighVolume") else if Percentile < over_Sold1 then Percentile.Color("LowVolume") else Percentile.Color("Normal"));

Well I finally did - here's the code:

Code:
declare lower;

def percentRankCount = fold i = 1 to length with count = 0
do
  if close[0] > close[i] then
    count + 1
  else
    count;

def percentRank = percentRankCount / length * 100;

plot PRank = percentRank;

That pretty much is the full code - here's an example of it using a Simple Moving Average:

Code:
declare lower;

input length = 50;

def rb = movingaverage(length,close);

def percentRankCount = fold i = 1 to length with count = 0
do
  if rb[0] > rb[i] then
    count + 1
  else
    count;

def percentRank = percentRankCount / length * 100;

plot PRankSimpleAvg = percentRank;

@droskill it shouldn't show anything when I paste that code, thanks
Hmmm....ok here's a simpler example that does work - not sure why that isn't working. This ranks closing prices over the 100 days.

Code:
declare lower;

input length = 100;

def rc = close;

def percentRankCount = fold i = 1 to length with count = 0
do
  if rc[0] > rc[i] then
    count + 1
  else
    count;

def percentRank = percentRankCount / length * 100;

plot PRankClose = percentRank;

Today's range is at what percentile of the previous 252 days - I have been trying to get this by modifying the above code. But I am having a difficulty. Can someone please let me know what I am missing in the below code?

I basically changed this
input length = 1; #ATR Length
input length2 = 252; #no. of Bars the PercentileRank uses to Calculate % Values

This is a clever concept - thank you. What would we add to this code if the label would actually show the value of the last measurement rather than just the name of the script?
