ATR Normalized Indicator for ThinkorSwim

[alvissome]

Hi there I'm new here and I'm trying to come out a thinkscript similar to the video below.

Adam Khoo uses it in combination with William R to determine market bottom. However I couldn't quite get the thinkscript portion of it, anyone is able to offer any insights that comes close to his?

what part don't you get the normalized atr?

 

[alvissome]

The thinkscript, the thinkorswim default only has ATR but not the normalized one. I tried writing but came nowhere near what he’s seeing.

I will take a look at creating one, see what I get.

declare lower;

input length = 14;
input averageType = AverageType.WILDERS;

def ATR = MovingAverage(averageType, TrueRange(high, close, low), length);

plot normal =( atr/close * 1000);

Could easily be all coded together with trigger arrows will look at that tomorrow.

I tested the idea and it has only found 2 times in 15 years it would have triggered, Tried running it on lower time frames than a weekly and it is of no value so not sure worth going any further.

What normalized atr are you using in TradingView?

Hi @inthefutures,

How do you rewrite the tradingview's code below in thinkorswim? Thank you in advance for your help. I am not too familiar with thinkscript and couldn't get it to work.

study(title="ATR Percent Rank", shorttitle="ATR Normalized", overlay=false)

source = close

atrlen = input(13, minval=1, title = "ATR Length")

lookback = input(52, minval=1, title ="Percent Rank Lookback")

atrp = percentrank(atr(atrlen),lookback)

plot(atrp, color=#ff9800, transp=0)

I think I came close, but it does not like my plot statement.

study(title="ATR Percent Rank", shorttitle="ATR Normalized", overlay=false)
;
source = close
;
atrlen = 13
;
lookback = 52
;

atrp = percentrank(atr(atrlen),lookback);

plot atrp (color=#ff9800);

Only work for Year 2009.

Per the requests in this post; I've created a version of this study. I think it's quite helpful in classifying the volatility of the market:

#APTR Percentile Rank for ThinkorSwim Version 1.0
#
#VERSION
# 2020.04.11 V1.0 @diazlaz - Initial Release
#
#
#INSTRUCTION
#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
#
#

declare lower;

input length = 10;
input length2 = 100; #no. of Bars the PercentileRank uses to Calculate Rank
input averageType = AverageType.WILDERS;
input paintBars = yes;
input showLabels = yes;

#LABELS
AddLabel (showLabels, "APTR Percentile Rank for ThinkorSwim Version 1.0", COLOR.ORANGE);

#APTR
def bottom = Min(close[1], low);
def tr = TrueRange(high, close, low);
def ptr = tr / (bottom + tr / 2) * 100;
def APTR = MovingAverage(averageType, ptr, length);

#Percentile Rank Calculation
def percentRankCount = fold i = 1 to length2 + 1 with count = 0
do
  if APTR[0] > APTR[i] then
    count + 1
  else
    count;
def percentRank = Round( percentRankCount / length2 * 100.0, 0);

#PLOTS
plot pATRRank = percentRank;
pATRRank.SetLineWeight(2);
pATRRank.SetDefaultColor(GetColor(8));

plot p25 = 25;
plot p50 = 50;
plot p75 = 75;

p25.setDefaultColor(COLOR.DARK_GRAY);
p25.HideTitle();
p25.HideBubble();

p50.setDefaultColor(COLOR.DARK_GRAY);
p50.HideTitle();
p50.HideBubble();

p75.setDefaultColor(COLOR.DARK_GRAY);
p75.HideTitle();
p75.HideBubble();

#END Of APTR Percentile Rank for ThinkorSwim Version 1.0

I have the same problem. The thinkorswim platform doesn't offer a "normalized" option... Only Wilder, Simple, Exponential etc...

Is there a way to add it to the mobile app somehow? Or did anyone found a solution?

Thanks!

@diazlaz Great job. What modifications are needed for the indicator to be used as a Custom Scan Study? Using just one of the pX's (25 or 50 or 75).

@diazlaz Thank you for the script! I have never been able to successfully scan for NATR in TOS. Are you aware of a method?
