If you use a '1' or 'yes' here it will always show the label, Otherwise you define a condition or an input selection-value that evaluates to 'true' or 'false' and reference that condition statement here. else if price == low then "low" see an example under 'VERTICAL LINES (3 STUDIES)'. is the enum value. else if price == hlc3 then "hlc3" An example is: def SlowK = StochasticSlow( 80, 20, 10, 10, smoothingType = "SMA" ).SlowK; Here you have omitted the price parameters. By Krill at http://groups.yahoo.com/neo/groups/TOS_thinkscript/info. Comment 1: The stochastics indicator can be confusing because it is referred to as: 1. GetDayofWeek, GetDayofMonth, RegularTradingEnd and RegularTradingStart all utilize a yyyyMmDd input parameter format:The same output format as GetYYYYMMDD(). plot Vol = volume; If your answer was not 7, rethink it. Defines the price with which the standard deviation and distance are calculated. advnDecl = (advances - declines) / (advances + declines); Studies may be used within a fold. This nested-if reads as: If close is greater than the open then plot the close. The user may adjust the length of the channel as desired from within the settings panel. else if price == imp_volatility then "The price-variable selected is current imp_volatility = " + AsPercent(imp_volatility) The value of the index can be used in the do . There are many readers available but the recommended one is listed in the References at the end of this document. Functions that take a look back value or length, such as average( data, length ), highest( data, length ), etc. Also an esteemed TS coder has written the '3X oscillator' for use specifically with the 9/30 setup.

Conditional coloring can also be had with the addition of if.then..else statements. level = 0; I constantly look advnDecl = AbsValue(advances - declines); or 15 -10 = 5 = change difference; 5/10 = 0.5; 0.5 X 100 = 50% increase. Access to real-time market data is conditioned on acceptance of the exchange agreements. Mobile compatible. Each RGB component ranges in value from 0 (meaning none or 0%) to 255 (meaning the max 100% value). 1600. def Past_Mkt_Start = IfSecondsTillTime(Mkt_Start) > 0), 0, 1); def Past_Mkt_End = If((SecondsTillTime(Mkt_End) > 0), 0, 1); def MktIsOpen = If(Past_Mkt_Start and !Past_Mkt_End, 1, 0); def day = GetDay(); def lastDay = GetLastDay(); def Today = If(day == lastDay, 1, 0); def Show = If(IntraDay and Today, 1, If(!IntraDay, 1, 0; Or do I have to do it myself? This section holds questions and support requests related to our premium ThinkorSwim indicators. left mouse key and drag the chart to the left for as much right-space as you want. A linear regression channel is a representation of trend direction and volatility. Example 7 = A more flexible code having selectable price, length and direction (Choice). PolarizedFractalEfficiency_SFL . Using the '+' symbol is much easier to master and is recommended. Stocks do not have a perfect efficiency reading of 1. To make an 'Info Bubble' for a study and strategy: Above the code lines, place #hint: ???????? If you sort by this scan, the higher ratio stocks will have smoother trends, while reading between .30 to 0 will show very volatile stocks. else if exchange == exchange.AMEX then "AMEX" "ADX" > 40 && DIPlus(). plot MA200= MovAvg200; This means that 'nice' is the with that fold has been keeping tract of internally and '+ idx3' is the current loops calculated value that is to be added to nice. You like trading. I like making it easier. Scanning for stocks that have just crossed over produces less hits that a scan that looks for a xOver within one (1) day. You adhere to the main client requirements and use basic features to build the initial. At times you want to compare the charts DMI with another symbol. The two ways above example, "value1 is what percent larger/smaller than value2." I am looking for something that will calculate linear regression of a series, using the least squares method. Using the '+' formatting syntax is recommended and has replaced the original 'Concat' syntax used by the author. For value1 = 85 and value2 = 38 then: 85 /38 = 2.24; 2.24 X 100 = 224%. Color-assigned-index-numbers are explained in the separate topic. try to create a trendline along up and downs of this reg trend line and i see some interesting patterns. The expression used for the IDataHolder dynamic offset often has a length parameter in it and that length parameter is also the value used for int max offset. Another example is 'do nice + getValue(close, n, length - 1)) / length'(a simple moving average) which gets a close value; divides it by a length variable; and adds it to the internal variable, nice. Subjects are often named differently. The names assigned and are persistent variables. Defines the time scale value corresponding to the begin point. may be any TOS features worth knowing. Length. There are no limits to the number of conditional statements but they follow the format if..then.else if..then..else if..then..else. So within that context, certain functions make no sense, like barNumber(), HighestAll() to name a few, also rec variables. The fold will do some action but that action may be subject to certain conditions. ', Alternate 1 = Stocks in top 10 percentile of their 52-week high-low range, Alternate 2 = Stocks between 47% and 53% (or the middle of) their 52-week-high-low range, Alternate 3 = scan to find stocks which made new 20-day-low, Alternate 1: Stocks that have a RSI under 20 for 3 days and a closing price above the 200 SMA, Plot scan = (RSIWilder(length = 2) < 20 && RSIWilder(length = 2)[1] < 20 && RSIWilder(length = [2] < 20 && Close > SimpleMovingAvg(length = 200)), Alternate 2: stocks that have a 3-day RSI under 20 a closing price above the 200 SMA, Plot Scan =(RSIWilder(length = 3) < 20 && Close > SimpleMovingAvg(length = 200)). The reverse is also true when a down-sloped RED bar shows.This is the picture of the subject: Although TOS provides many powerful features, there are also other very useful resources on the Net. //println "l2>${l2.split(/\-/).size()} anyone have any success with Usethinkscript indicators? Try different 'find' entries if you are not successful. Regression channel consists of two parallel lines plotted equidistantly above and below the Regression Line. Price. Traders of all skill levels use our forums to learn about scripting and indicators, help each other, and discover new ways to gain an edge in the markets. Assuming that 20,131,107 was returned it can be formatted into a normal view as follows: AddLabel(yes,"Converted getYyyyMmDd() = " + getMonth() + "/" + getDayOfMonth(getYyyyMmDd()) + "/" + AsPrice(getYear()) ,color.pink); Returns the number of days from the specified date in YYYYMMDD format. The current value would be + 1. You can use either the ThinkScript functions or calculate the variables for Linear Regression and Standard Deviation which ever you prefer. You may add these info bubbles to your studies. Use of a switch inside a switch is possible but is very complex. AD.DefineColor("Down", Color.DOWNTICK); Please read theRisk Disclosure Statementprior to trading futures products. The benefit of doing this is that the builtin and your modified copy stay adjacent in the list and it helps you to keep track of what you may have done two months ago. Granted that not all personal preferences are the same. concept applies to all aggs. Those are the default parameters and cannot be changed because they are in a pre-defined study which is not editable. addLabel(!ShowBubble,"%-value-bubbles available when above " + Ref_val + "% reference line", Color.white); All date/time functions having parameters, except for SecondsFromTime and SecondsTillTime, use a parameter format of YYYYMMDD. Editing existing studies does not have the wizard accessible but the wizard in the following picture can be used and the wizard result can be copied for pasting in the existing study editing. The average daily volume length is based on the variable inputted length. The PDF format was selected, with extra features, like the hyperlinked Table-of-Contents, to make subjects easily found. There are three ways to do this. Date/Time. def dayOpen = if firstBar then high else dayOpen[1]; plot x = dayOpen; AddChartBubble(Isnan(Close[-1]) && ShowBubbles, MovAvg200, (MA2_length + "-Day MA"), Color.DARK_ORANGE); addLabel(1,"Mov Avg input price choice = " + (if price == close then "close" The people on the ThinkScript Lounge and Yahoo TOS_ThinkScript generously contribute much time and effort helping those learning and using ThinkOrSwim and ThinkScript. Application will automatically adjust the slope of the lines based on linear regression. def Example2 = Sum(MACDHistogramCrossover(), 8) ;#This plots the count of "Positive to Negative" crosses in the last 8 bars including the current bar. You can edit the study to change the symbol or the type of plot, i.e. The above reads as abased on the close, simple average1 of length = 15 crosses above exponential average2 of length = 30.'. linear regression of the ProjectionBands study. This will create an error. advnDecl = advances - declines; color.CYAN or color.LIGHT_RED. Not all clients will qualify. advances = close("$ADVA"); The code shown is very reusable. During trading hours this is also todays date. plot trendLine = if start then startPrice else if end then endPrice else double.nan; Def DayOfWeek = GetDayOfWeek(First(yyyymmdd)); #Mon =1, Tues =2, Wed = 3, Thurs = 4, Fri = 5, Sat = 6, Sun = 7, Comment 1: 'SecondsFromTime' and 'Seconds TillTime' work smoothly during market hours but beware after-hours. In addition to that, a neat trick is, while in the code editor, drag the editor window down so that you can see the charts label and header values. When editing existing studies and you want to use the wizard, you have two choices: 1. Comment:The following code plots when a cluster exists in the above code. else if price == hl2 then "hl2" SD of 1, 2 or 3 are arbitrary distances-from-the-average of a normal distribution curve, that people use for easy discussion or reference. def volTest = volume >= _volAvg * ( 1+ ( pct / 100 ) ); Specify begin and end points of regression line . Portable Document Format = the type of file format of this document. For intra-day only. A 'setup' is a term/title applied to a group of charts and indicators that are used to implement a trading strategy. If the index was to be 1 thru 10, the current value of price would not be included in the average because the first value would be price[1]. Even the label coding is neat. def avg = average(price, length)[1]; 1 to 366, 1 to 53, 1 to 12, and the year respectively. In general, success in terms of and algorithm of actions, and not some magic scripts. Or it may be a more complicated fold such as: fold i = 0 to 100 with price = Double.NaN while !IsNaN(price) do if getValue(high, -i) > 40 then getValue(high, -i) else Double.NaN; This finds the next high price value greater than 40 among the following 100 bars and terminates looping if price is no longer a number. else' format. "DI+" > DIMinus(). When it turns green you are in the safe zone. Re the recent release & Renaming studies. B- = Basic platform or coding subjects, fundamental principles, fundamental examples and how-to-dos, C- = Coding of studies, strategies, snippets, et al that accomplish a purpose/result, T- = A Tip or Trick on how you might use TOS or TS to accomplish a specific useful purpose, ?- = In the subjects heading, ? Conditions here do not preclude the 'do' statements from having an 'if' statement that may also set conditions but those conditions are used in getting the desired result from the 'do' statement. ), your script only runs once and only against the current (latest) bar. case increase: The code for swing lows is similar. Here is a example of the 'switch' function being discussed: The switch statement is used to control the flow of program execution via a multi-branch using the enum Def, and enum input: Its features are: It processes an enumeration: In this case 'input exchange'. This defines how many times the fold calculation loops on each bar. def = becomes Plot =. Also a S&P 500 sector comparison tool may be had at S&P 500 Sector Comparison. Also, this version allows the user to select the number of bars for the linear regression plot in lieu of the previous two studies that use the entire chart (all bars). input Mkt_Start = 0930;#hint Mkt_Start:Show market start time e.g. 'nice + idx3' then becomes the new value of the internal variable nice and nice is available for the next loops calculation. AddLabel(yes,"% Change compared to " + length + " days ago = " + Round(PctChange, 1) + "%",color.PINK); Alternate = current close as percent of the last-52-week-range. SUMMARY. AddCloud(CurrentPrice, Lower, Color.WHITE); JavaScript is disabled. Thanks to everyone here i was able to create a strategy i use into a tos strategy to backtest. def previousDay = if CountTradingDays(CurrentDate, LastDate ) == 2 then yes else no; Comment 1: The '==2' may be changed to represent any previous days-ago, Comment 2: CountTradingDays includes the CurrentDate and the LastDate in the count, Usage: The above two line are conditions that you use to restrict your data. This allows 'smlCount' to rise to 1000 and then it limits smlCount toa value of 1000. plot Test = fold i = 0 to 4 with x = 1 do x + i; What is the value of test? Premium indicators for ThinkorSwim platform. DefineGlobalColor("Purple" , CreateColor(160,32,240) ); See all predefined color constants: See predefined color constants. scan.SetpaintingStrategy(paintingStrategy.BOOLEAN_ARROW_UP); def Example3 = Sum(MACDHistogramCrossover(), 8) >= 2;#If the count of "Positive to Negative" crosses in the last 8 bars is greater than or equal to 2, then Example3 evaluates to 'true' (or 1). The syntax is: If(double condition, double true value, double false value); This is the simplest and easiest to use. Right extension. def Change = (price / price[length] - 1); Plot PctChange = 100 * change; Show label. VolAlert.SetDefaultColor( Color.GREEN ); This document also proovides a reference for future coding activities. addlabel(yes,"Vol as % of " + VolAvgLength + " agg-bar avg volume = " + aspercent(Round(data,2)),if data < 0 then color.RED else color.GREEN); #hint: Plots: 1. Hope you find this document useful. It likely is 'day' but doesnt have to be. case AMEX: advnDecl = advances / (advances + declines); If you want to see a dot anytime the condition is true, then remove the '&& !cross[1]'. or 15/10 = 1.5; 1.5 - 1 = 0.5; 0.5 X 100 = 50 % increase. Alternate 1: Todays cross of a 10-bar MA above 20-bar EMA. The labels will then have their centerline equal to the value of the line. onceperchartup.hidetitle(); Plot CrossUp = !mostRecentOnly and crossingup; Better trades with simple strategies, proven indicators, and a community of support, The Best Collection of thinkorswim Scripts, 2,000+ Traders in the Private Discord Community, 50+ Proven Strategies, Setups, & Chart Examples from Pro Traders, Get Answers To Your Questions From Seasoned Traders.

It appears that "TOS and Thinkscript Snippet Collection" hasnt been update in If most datapoints are widely scattered, the SD will be larger (i.e. The built-in ZigZagPercent study demonstrates the excellent use of conditional showing of the label itself, the use of the + syntax and conditional coloring. Calculates the simple moving average using fold. 'Bearish'. settings (the agg dropdown). You can tweak it in the input or the code how you see fit for you. Returns the date of the current bar in the YYYYMMDD format. Trading privileges subject to review and approval. 5 run average: 4.752 s. Relative performance: 0.7% faster. add-ons, and strategies, private VIP-only forums, private . Comment: This is a good example illustrating the use of the Assert function. Pre market scans are not very efficient. For anchoring a regression line to some event such as a fractal pivot many find it easier to use the mathematical approach rather than the TS function. This will do it. "Span A", Ichimoku(). This is a scan that works well in a dynamic watch list with your favorite companies to trade. plot Data = ( price - close1) / close1 * 100; Privacy Policy. def crossingover = close("Greatest Show Ever! MACDHistogram Crossover default parameters of fastLength = 12, slowLength = 26, MACDLength = 9, AverageType = EMA. On an intraday chart the IV will show N/A and the HV will be annual HV. Any suggestion for improvement or inclusion are welcome. The date and time functions take a lot of time to learn and much usage to feel comfortable with them. ?-DAY and a ?? Comment: A good example of a nested fold. This can be done by setting up a grid of 4 components, as an example. For example, there is a 9/30 setup that is openly discussed on the internet. Vol.SetLineWeight(3); Plot Stoch_Slow_OS = StochasticCrossover(stochasticMode = "StochasticSlow", crossingType = "Oversold").signal; The above reads as 'scan for when the 14 period slow stochastic crosses below 20'. The statement "input Show_ChartPeriod = yes;" reads: assign (or set) the memory location labeled 'Show_ChartPeriod' to yes (boolean TRUE); The double "==" is the logical equality operator. level = 0; ` else if price == high then "high" DAYS AGO, Return 'the day-of-the-week' of the first bar of the chart, SecondsFromTime() & SecondsTillTime() & others, C-'BATTLE OF THE BANDS' RE IMPLIED VOLATILITY, C-VOLUME LABEL AS A PERCENT OF AN INPUTTED X-DAYS-AVG-VOLUME, T&C-EXAMPLES OF THE USAGE OF THE 'SUM' FUNCTION, C-HOW TO SHOW WHEN A CANDLE PATTERN EXISTS ON A CHART, C- IMP_VOLATILITY() PERCENTILE PLOT WITH LABELS, C-MINUTES-AGO SINCE A TURN-UP OF A MOVING AVERAGE, C- NORMALIZED MACD AND STOCHASTIC PLOTTED WITH A SQUEEZE INDICATION, C-ILLUSTRATION OF SAME RESULT WITH DIFFERENT CODING, C&S-FLEXIBLE 200-DAY MOVING AVERAGE PLOT AND SCAN, C-AN ALTERED 'PERCENTCHG' TO MAKE IT MORE USEFUL, C-LINEAR REGRESSION OF THE PROJECTIONBANDS STUDY, C-CLARIFICATION OF THE FOLLOWING THREE COMPARISON STUDIES, C-COMPARISON OF ALL SECTORS OF THE S&P 500 (SPX), C-PERCENTAGE PRICE OSCILLATOR (PPO) WITH COMPARISON SYMBOL, C-'Ichi_TK_Exit_Warning' --- AN EARLY ICHIMOKU T-K EXIT STUDY, C-'IchiOneGlance'--ALL MAIN ICHIMOKU CRITERIA IN DASHBOARD FORMAT, C-'Ichi_Signals'IDENTIFIES ALL MAJOR ICHIMOKU SIGNALS FOR LEARNING OR USE, WLC-PRICE-TO-EARNINGS (P/E) RATIO FOR A WATCHLIST COLUMN, WLC-WHEN A DIVERGENCE EXISTS BETWEEN PRICE AND THE MACD, S-DMI_OSCILLATOR SCAN FOR TRENDING-UP STOCKS, S-SCAN RSI UNDER 20 & CLOSE > 200-DAY SMA, S-SCAN CROSS OF STANDARD DEVIATION CHANNEL, S-NOTEWORTHY RESOURCE FOR PREDEFINED SCANS, S-NEW BULLISH CLOSE ABOVE THE ICHIMONU CLOUD, S-CROSSING ABOVE & BELOW THE ICHIMOKU CLOUD, T-A REFERENCE RECALL OF A STRATEGYS RULES (SETUP), T-USING MULTIPLE TIME FRAMES TO PLAN ENTRIES, T-WIZARD ACCESS FOR EDITING EXISTING STUDIES, T- VERTICAL LINES AT MARKET OPEN AND CLOSED TIMES, T-EASILY VIEWING CHARTS OF STOCKS IN A LIST, T-NAVIGATION VIA KEYBOARD HOTKEYS vs THE MOUSE, T-DEFINING AND APPLYING CONDITIONS IN A STUDY, http://demo.thinkorswim.com:7001/manual/metal/thinkscript/reference/Functions/Others/If.html, http://demo.thinkorswim.com:7001/manual/metal/thinkscript/reference/Reserved%20Words/if.html, https://tlc.thinkorswim.com/center/charting/thinkscript/reference/Functions/Look---Feel/GetColor.html, https://www.thinkorswim.com/tos/thinkScriptHelp.jsp?laf=dark#constants, http://en.wikipedia.org/wiki/List_of_colors:_A%E2%80%93F, http://en.wikipedia.org/wiki/X11_color_names, http://tda.thinkorswim.com/manual/metal/thinkscript/tutorials/advanced/referencing/other%20study.html, https://tlc.thinkorswim.com/center/charting/thinkscript/tutorials/Chapter-13---Past-Offset-and-Prefetch.html, http://groups.yahoo.com/neo/groups/TOS_thinkscript/info.
