03:23 Nube: Mornings, all.  Something I though may help people visualize the index in a Fold
#
# Visual Aid for Fold Index Length
# Nube
# v.01 9.18.18
# Sum of bar numbers using using Sum() and Fold

input barsAgo = 5;
def bn = BarNumber();
    # Subscript for n bars from current
script barsAgo {
    input n = 0;
    def bn = BarNumber();
    def c = close;
    def barsBack = if   !IsNaN(c[-n]) && IsNaN(c[-(n+1)])
                   then bn else barsBack[1];
    plot barsAgo = barsBack;
}

def checkFold = fold i = 0 to barsAgo with b do b + GetValue(bn,i);
def checkSum  = Sum(bn,barsAgo);

AddChartBubble(bn == barsAgo(barsAgo), HL2, "Bar  \n" +barsAgo(barsAgo),Color.Gray,0);

04:58 Nube: Bonds down, dollar down, metals not up is going to be an environment that takes some getting used to.
04:58 Nube: Sorry, Teach. Wrong classroom.
05:22 bmckinney: Is there a way to turn off the sound on TOS without having to turn off the sound on my computer?
05:23 DMonkey: whats making a sound in TOS?
05:24 bmckinney: Closing bell, opening bell, and alerts
05:25 bmckinney: I'm in a classroom, and I need volume on my computer, but I don't want random bells going off.
05:25 DMonkey: alerts....use sound.nosound / opening & closing bell your own your own....
05:31 AlphaInvestor: Settings - Application Settings - Notifications - turn off the Alerts checkbox
05:32 DMonkey: the best solution may be focus on class........
05:43 MTS1: and understand windows / mac; not really a TOS question
05:47 AlphaInvestor: Dmonkey +1
05:54 UpTheCreek: The Windows Volume Mixer can also be used to control the volume and mute the sound from each application that is loaded.  Right-click on the speaker icon.
05:55 JohnnyQuotron: Good morning all...
05:58 Vimes: Ahoy, Matey
06:05 Nube: I still don't even know how to make Windows not ask me for my password, I'll never learn that volume control trick.
06:13 mike__w: Alpha - the other day you suggested I check out FOLD. I watch Mr.Script's previous webinar to help better understand it and came up with with this.
06:13 mike__w: def aug = 20180831;

def barsaway = fold counter = 0 to 1 with lastmonth do (CountTradingDays(aug, GetYYYYMMDD()) - 1);

def x = highest(high[barsaway], 22);

plot p = x;

06:14 mike__w: I still get an error when using highest but the FOLD part works, so thanks for helping me learn something new
06:20 MTS1: Is this a leaning exercise Mike at this point to learn fold while you have your combined indicator working?
06:20 DMonkey: bigworm....you on?

06:21 bigworm: i am
06:21 bigworm: hows the morn
06:22 DMonkey: this is for you....
http://tos.mx/AKrMVG
06:22 bigworm: thank you so much!
06:22 MTS1: Can I borrow it also? ;)
06:23 DMonkey: nope.....
06:23 UpTheCreek: lemme guess, some wacky  zgauss mashup
06:23 DMonkey: lol
06:23 MTS1: thanks DM!
06:24 DMonkey: utc...of course....
06:24 mike__w: MTS1 - yes, just a learning exercise I came to accept that combinding all three won't work but Alpha suggested I check out Fold to see if it could be a possible solution. but I'm still getting the CL function indexer high error
06:25 Nube: Mike, did you see the snippet I posted the other day for getting which bar last months high occured on?
06:27 JohnnyQuotron: Nube... there were some excellent educational elements of that script.  Thank you.
06:27 bigworm: dmonkey, is the alpha and beta always adjusted this way? to put the distribution 1 sd inside the curve for the 4 pole?
06:42 mike__w: Nube - I did check it and appreciate your help but I never got this line to plot anything
06:42 mike__w: plot atBar = if priorMonthBars && high == priorMonthHigh then BarNumber() else Double.NaN;
atBar.SetPaintingStrategy(PaintingStrategy.Boolean_arrow_up);
06:44 UpTheCreek: well look at the code and understand when it WILL plot something.  Is the criteria met by your chart?
06:47 mike__w: UTC - below is the full code, my understaningd is that the critia will always be met because there will always be a highest high in any given month.
06:47 mike__w: #TsL for Mike_W from Nube
# gets highest high of prior month

def month = GetMonth();
def thisMonth = GetLastMonth();

plot data = month;

data.setpaintingstrategy(paintingStrategy.Values_Below);

plot priorMonthBars = month + 1 == thisMonth;
priorMonthBars.SetPaintingStrategy(PaintingStrategy.Boolean_arrow_down);

plot priorMonthHigh = HighestAll( if priorMonthBars then high else Double.Nan);

AddLabel(1, “This Month” +thisMonth+ “ Prior Month: “ +(month -1), Color.Gray);

plot atBar = if priorMonthBars && high == priorMonthHigh then BarNumber() else Double.NaN;
atBar.SetPaintingStrategy(PaintingStrategy.Boolean_arrow_up);
06:50 UpTheCreek: welcome to debug.  WHEN does the code plot the arrow?  2 conitions have to be met.  Are they?
06:55 mike__w: No there not! thanks for making me think, I had the SPY up but when I switch to ATI I got a print. Will look into it more
06:59 UpTheCreek: thinking is pretty critical in this endeavor
07:00 UpTheCreek: :)
07:00 Nube: Thus why I dislike this endeavor
07:23 artx: I using the Williams Fractal Pattern indicator with default settings.
07:23 artx: But it won't show unless I update the chart.  How do i get the chart to update more often?
07:25 artx: My candle sticks update in real time but the Willams Frac. Ind won't appear unless I type in another symbol name and then retype in the symbol name of the chart Im watching.
07:29 MTS1: artx; confirm how many charts / swatchlists you have open (how much data you may be pulling), make sure you have good internet speeds, and make sure you don't have memory for TOS set to high. Otherwise live support is the best option as they can connect to your TOS instance.
07:31 artx: thanks MTS1, I have the memory set to the Max I think.  I thought that woul be a good thing. But I will change it and close some watchlist.
07:31 MTS1: for normal use memory should be max 2 or 3 GB; check on the maintenance wheel icon on the login window. Initial memory can be about half of that or 1GB. Should be less on a machine with less than 4GB available.
07:31 MTS1: No is counterintuitive for TOS'; Java has issues cleaning up memory when you give it too much.
07:32 artx: ok thanks for the explination
07:34 MTS1: artx; regarding watchlist; especially considering dynamic watchlists / quotes, or custom (script) columns.
08:07 mvm: Does anyone know whether you can extract indicator values for a specific time period from TOS? E.g  RSI(14) values for AAPL for past 30 days. Need  the  data in  CSV or Excel format for  analysis. Thanks
08:14 UpTheCreek: yoiu can export watchlist columns to Excel, that's it.
08:15 mvm: Thanks.  My understanding is that the watchlist  columns can only show today's value but I am looking for historical values as well
08:15 mvm: Is there a way to do that via watchlist cols
08:18 UpTheCreek: you can put custom code in cols.  there is no good way to do what you want.
08:20 MTS1: mvm; you can create a strategy or combination of strategies to put in buy/sell orders at certain points to extract those data points. But better way to analize is use other source or create analysis in TOS by doing the math / stats in tos.
08:20 mvm: Can it be done via Thinkscript -?  seem s like a simple extract of data . The values can be charted so there should be  a way to download the data to Excel
08:20 MTS1: the data is free and not simple to extract.
08:20 MTS1: not sure why you think it should be. .
08:22 mvm: You can get historiclal price data   from many sites - thi s is trying to get historical indicator data. Does anyone know if Yahoo or other sites provides this data
08:22 mvm: if it cannot be done in TOS
08:23 TICKZ: Hi guys.. does anyone have a studie that alerts pin bars and doji at daily atr levels ?
08:23 UpTheCreek: chat rules prohibit mentioning of nonn-ToS sites
08:25 mvm: Ok. Appreciate any help
08:25 UpTheCreek: the admins will give lots of help  :)
08:53 Vimes: mvm, i don't have a solution but can you tell us what you want to di with the historical rsi data?  it likely could be done native in tos
08:56 mvm: I want to perform additional  analysis in Excel on sveveral  tech indictaors - RSI, ROC, Chaikin with some custom statistical analyses I've ceated in Excel. Just need the raw dta  values extracted that are plotted on teh graph
09:09 MTS1: The suggestion is to replicate the statistical analysis to TOS if possible; you can probalby collect the stats you want and then run it on any chart. Otherwise another solution is the best option, either TDA API or another provider.
09:10 UpTheCreek: I'm not even sure if the API is going to be helpful.
09:12 MTS1: true; that'd just pull price data; still have to replicate the indicators. . For TOS replicating the stats is probably best, extracting data can only be done wiht a strategy; you could buy on every odd minute and sell on ever even minute at a 'price' that represents the indicator value. API or 3rd party includes having to replicate the indicators.
09:28 AlphaInvestor: Mvm - get your historical data from another site. RSI(4) is easy to calcualte in excel
09:29 wharfie: Good Morning ... how do I  run a scan that shows stocks in a 52 week downtrend?i tried using one that is below it's MA but essentially that can be an uptrending stock that is just trending below it's MA right?
09:37 ameriman: uptrending stock won’t trend below MA
09:37 MTS1: Right; question is how you define downtrend. Can be longer term MA value below 52 weeks ago, sum of up weeks vs down weeks, sum of weeks with faster MA below slower ma, or probably many other options you could think off.
09:39 Vimes: close<close[52]; on a weekly scan - but likely not a reliable def of a downtrend
09:39 ameriman: According to “market makers edge”, market makers use either 8 ema or 20 ema for quick trend determination
09:40 AlphaInvestor: market makers are using 1 min or 5 min charts ... not year long charts
09:41 wharfie: Thanks guys. I just tried to scan within 3% of the 260 day New low.
09:41 ameriman: The book says whatever time frame you are using, they use those ema, and then they also do multi time frame analysis to make sure all time frames aligned in trend
09:42 ameriman: Before they take trade on lower time frames
09:49 UpTheCreek: ok, fine, there is a moving average scan built in to the scanner
09:55 GraceGu: Hi , I was advised by Tos associate to check with you guys, if someone knows how to scan the top/bottom divergence pattern?  I attached the picture --Tsla yesterday's hourly chart for your reference.thank you in advance.
09:58 UpTheCreek: ...someday they will shrink mobile screenshots
09:59 GraceGu: sorry for that, I am the first time in this lounge
09:59 GraceGu: let me see if I can withdraw it
09:59 UpTheCreek: if you are on mobile there's not much you can do
09:59 GraceGu: no, I am use the PC
09:59 MTS1: Grace; I don't see indicator for 'top/bottom' divergence; just trend lines? Not sure what you're scanning for indicator related on that pic
10:00 UpTheCreek: for the scanner to find something, you have to describe it mathematicallyt
10:00 GraceGu: What I'd like to do is to scan the stocks with top/bottom divergence
10:00 UpTheCreek: if you can do that, then code can be applied
10:01 MTS1: define 'top / bottom' divergence?
10:01 UpTheCreek: do you have specific criteria in mind?
10:01 MTS1: repeating does not clarify;)
10:01 GraceGu: In a time period, the price is going higher but the MACD's top is going lower
10:02 MTS1: I believe there's a MACD divergence indicator on Mobius' MuTrade
10:02 MTS1: (though he's against using it iirc)
10:03 GraceGu: ok, I got it,
10:03 GraceGu: thank you for all your kind help.
10:09 MTS1: Grace; I stand corrected, don't think it's on his mytrade, but would check for other indicators. Here's a link; paste this under setup - open shared item: aG0Omj
10:09 MTS1: make sure to read the notes in the script.
10:16 ameriman: Alexander Elder has written a whole book on MACD histogram divergences, he says MACD histogram divergence works best only when analyzed in a particular way when in between the two Diff peaks Diff goes beyond zero line, otherwise regular way doesn&apost work well
10:23 AlphaInvestor: Ameriman - I have heard that crossing zero logic
10:24 AlphaInvestor: I still think they are informational but NOT tradable
10:24 AlphaInvestor: divergence = price and indicator are telling you two different things. But you don't know which one will change to get back in alignment
10:25 GraceGu: yes, they are informational, but they can give you some alerts for the top or bottom will come soon
10:25 GraceGu: I mostly use them in future daily trading,  it helps to make the decision
10:27 ameriman: AI agreed, even the zero cross method hasn’t worked well for me when price is trending, it works when sideways range
10:27 AlphaInvestor: by Informational I mean - Somethings up ... watch carefully ... but still not directly tradable
10:28 GraceGu: yes, agree, not directly tradable
10:29 GraceGu: by the way, not sure , is there someone in the lounge  using conditions trigger  to trade directly?
10:29 harndog: Grace - No Retail AutoTrading in TOS
10:30 UpTheCreek: but conditional orders driven by simple scripts are supported
10:30 JohnnyQuotron: amer...I have never seen a MACD strategy that consistently makes money. That is not to say they are not out there, or that I have seen every MACD strategy.   So please, if you have seen a MACD strategy that is repeatable and profitable, please share it.  I think there is just too much lag in the typical MACD setup for it to be repeatable.
10:31 marketcoding: How do I add a marketwatch column to show yesterday's close?
10:31 harndog: Market, have you taken a FREE platform tour?
10:31 AlphaInvestor: put this in a column at D aggregation      CLOSE[1]
10:31 marketcoding: Correction:  How do I show "yesterdays High"
10:32 harndog: A good starting place is having questions and taking a free platform tour. Contact support@thinkorswim.com
This is a lounge of volunteers who do not work for TOS.
We are not TOS support, just experienced users interested in coding, and helping others learn to code.

When you're setting up your platform tour, request the chat room scripts created by TOS support.
When looking for scripts ask a search engine: Thinkscripts, TOS scripts or check out MyTrade/Mobius
10:32 harndog: Vend me a soda, AI...lol
10:32 UpTheCreek: Grace, no regular here has ever admitted to using conditional orders on a frequent basis
10:33 AlphaInvestor: Harn - dat was too easy to force them to learn a bunch of thinkScript
10:33 harndog: +1
10:33 AlphaInvestor: Up - I have never used a Condition Order ... Period
10:33 harndog: Only when ordering with my family...:)
10:34 UpTheCreek: and your intchy finger is on the mouse to sell off your TRLY
10:37 mthfr_vaxxed: im trying to develop a conditional order i can fire off after good signals. not there yet.
10:38 ameriman: JohnnyQuotron agreed with what you said, that is why I dont use it anymore
10:39 bigworm: you on mobius?
10:42 ameriman: JOhnny there used to be a trader in shadow chatroom who used MACD histogram divergence but he used it discretionarily along with tape reading and price action, he was very successful daytrading 60% annual return on account size on a million dollar account. But I have not been successful with it
10:42 Splectacular: Hi everyone ; first time here, are there any think sript people that have created linear channel regression scans for price approaching plus or minus 2 sigma? :)
10:47 mthfr_vaxxed: #Mobius  channel scan
# LRC Variable Scan
input price = hl2;
input n = 252;
input widthOfChannel = 69;

def MidLine = InertiaAll(price, n);
def dist = HighestAll(AbsValue(MidLine - price)) * (widthOfChannel / 100.0);

# Scan only allows one plot. Set plot to Upper or Lower and def to the other
def "Upper Band Cross"  = close crosses MidLine + dist;
plot "Lower Band Cross" = close crosses MidLine - dist;


10:47 mthfr_vaxxed: change your width of channel to 2 sigma
10:53 bigworm: whats up mthfr
10:54 bigworm: I just got my textbook for machine learning.  Super different from what I have been reading all summer. :(
10:59 mthfr_vaxxed: i liked this article "Machine learning - is the emperor wearing clothes?" ... favorite quotes ... "jargon in machine learning usually doesn't deserve the shock and awe the name inspires". and "quit anthropomorphizing machine learning already".
11:00 mthfr_vaxxed: textbook you wanted? or for a ML class?
11:00 bigworm: its for class
11:00 Vimes: Spectacular, there is also a built in std deviation channel scan from TOS - add study filter>statistical>standarddeviationchannel
11:00 bigworm: learning with kernals
11:00 bigworm: looks like a big proofs book
11:04 mthfr_vaxxed: dont know much about svm actually. gotta read more
11:04 Splectacular: ?Sorry just got back is there a link that you can  put in  the chat room?
11:05 bigworm: just a way to classify data
11:05 Splectacular: I am not a coder lol :)
11:06 AlphaInvestor: I am too lazy to copy that , can you please make it even easier for me - SMH
11:07 Splectacular: I know I can copy it sorry I just dont know where to past it  :(
11:08 AlphaInvestor: LEARN
11:08 mthfr_vaxxed: study button. looks like a chemistry flask
11:08 Splectacular: yes I will
11:09 Splectacular: yes I will thanx a bunch!
11:13 Vimes: there is a built in scan for std deviation - just use the tool provided from tos
11:15 Splectacular: @mthfr_vaxxed yes I see it thanx...let me ask how do you know what number corresponds to 2 sigma  to replace the "69" in the code were it says:  "inputwidthofChannel =69" ?  thanx
11:16 Splectacular: @Vimes : thanx!
11:25 BenPotter: Hey does anyone know how to get papermoney started?
11:25 BenPotter: I would like to try day trading that way before i get into it with real money
11:25 mthfr_vaxxed: need to learn gaussian statistics. then you'll know the answer. bell curve. and then study mandelbrot and realize there is room for error because life isn't "normal"
11:26 BenPotter: Anyone?
11:28 FrankB3:   BEN::  call trade for a free tour of TOS
11:29 Ron1982: Hi, I would like to try an strategy that has the possibility of defining a maximum amount of days to keep the position and then close it. So, Is there any function or script that allows to count the number of days from the day I opened the position and compare it to a limit amount of days?. Thanks
11:29 Splectacular: I know  guy that worked with mandelbrot
11:30 Splectacular: He is into  the fractal energy thing ;)
11:35 MTS1: Ben; you have the choice on your login screen
11:35 mthfr_vaxxed: im reading taleb's book still. he's a fan. the book is a little annoying though.
11:36 MTS1: Ron; yes you can use recursion in a script; check out chapter 10 of the TS Tutorials.
11:36 mthfr_vaxxed: what else you got besides looking for 2 sigma events?
11:37 bigworm: so for a gaussian z score , should the length of the gaussian be the same length as the normalization moiving average and sd length
11:37 MTS1: Basically you record when the entry order is triggered, and add one on each subsequent bar till your max is reached and use that for the close order.
11:37 MTS1: OR you can record the BarNumber() and calculate the difference with the current bar.
11:38 MTS1: ^Ron
11:43 MTS1: yw. .
11:43 bigworm: who ron
11:44 JohnnyQuotron: I need a little help with math theory... At least I think its math theory.
I have data for which I have created a five peiod Gaussian Mean using the Mobius script.  The line is still choppier than I would like for trend identification purposes.  Am I better off:
a: Increasing the Periods in the Gaussian calculation
b. Smoothing the Gaussian Mean with an SMA smoothing factor
c. Smoothing the Gaussian mean with a Gaussian smoothers

thoughts? Advantages or disadvantages of each?
11:45 bigworm: so you smooth it
11:45 AlphaInvestor: You are better off finding a series that isn't chopping
11:45 UpTheCreek: what is a Gaussian mean?  a mean you calculate after you Gfilter the values?
11:47 mthfr_vaxxed: im assuming john ehlers 4 pole gaussian filter
11:48 JohnnyQuotron:  # Trying to achieve Normal Distribution
# Mobius
# V01.09.2015
#Hint: Plots a Gaussian Mean with Standard deviation Envelope. If Normal Distribution is met, then at minimum, 68.2% of the close values should be inside a One Standard Deviation Envelope and 95.4% of the close values should be inside a 2 Standard Deviation Envelope.

def c;

beta = (1 - Cos(w)) / (Power(1.414, 2.0 / betaDev) - 1 );
alpha = (-beta + Sqrt(beta * beta + 2 * beta));
G = Power(alpha, 4) * c +
                 4 * (1 – alpha) * G[1] – 6 * Power( 1 - alpha, 2 ) * G[2] +
                 4 * Power( 1 - alpha, 3 ) * G[3] - Power( 1 - alpha, 4 ) * G[4];

GaussianMean = G;

11:49 JohnnyQuotron: please ignore the hint... its a left over
11:50 Splectacular: @mthfr_vaxxed  Not much else just trying to coupl those events with multitime fram MACD analysis ...
12:02 UpTheCreek: well the hint pretty much describes Gaussian filtering, which is intended to force the data series to a Gaussiian or 'normal' probability distribution function. not smoothing in a MA sense.
12:02 Ron1982: Hi MTS1, thank you very much for your help. I will check  chapter 10 and follow your recommendation. Thank you again
12:03 cajun: JQ, ill venture a wild guess... and suggest increasing the periods. 5 is small for an approx of normal
12:10 JohnnyQuotron: I really wish I had taken more math in college rather than accounting....
12:13 mthfr_vaxxed: never too late. turn off tv. read more books.
12:13 mthfr_vaxxed: im dusting off the cobwebs
12:14 AlphaInvestor: JQkpa - Kahn Academy
12:14 AlphaInvestor: I had to re-learn Calculus to help my daugher pass her university class - you can teach an old dog new tricks
12:15 JohnnyQuotron: alpha... on Kahn now.
12:23 JohnnyQs_BackupWks: On a different subject.  The distribution among the Sectors today is astoundingly large.     http://tos.mx/hHkI9U
12:24 UpTheCreek: speaking of distribution, anyone know exactly how money flow in and out of ETFs is calculated?
12:25 Tb8: JohnnyQ: Do you have a buffer from the start of the day?
