Formatting is possible using HTML tags. "Upper_Band"[1] and MACD() > 0 and MACD() > MACD()[1]. Each RGB component ranges in value from 0 (meaning none or 0%) to 255 (meaning the max 100% value). Def Example6 = sum(close < close[1],5) == 5;# The has declined for the last 5 bars. This is a hard-fast rule that often comes into play. SecondsFromTime and SecondsTillTime use a HHMM format. Or do I have to do it myself? View full post. 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. This date corresponds to the day whose trading session contains the current bar. advances = close("$ADVN"); : The syntax for GetValue is: GetValue(IDataHolder data, IDataHolder dynamic offset, int max offset); A discussion of fold would not be complete without discussing the GetValue function. Complexity may become an issue especially if the servers are loaded up. Arrow.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP); case "Advance/Decline Ratio": see an example under 'VERTICAL LINES (3 STUDIES)'. Our forum can be intimidating, if not overwhelming. For value1 = 85 and value2 = 38 then: 85 /38 = 2.24; 2.24 X 100 = 224%. The aggregation for this is day. VolPct.SetPaintingStrategy(PaintingStrategy.LINE); else if type == type. The distance at which the lines are plotted can be calculated using different algorithms. }. else if price == ohlc4 then "ohlc4" Inertia ( IDataHolder data, int length); Description. to go to that page When there, you can return to to the TOC by clicking Return to TOC. The resulting interpolation function for each set of bars is defined by equation: y = a * current_bar + b.See the following example for details. Visible. Only a 'Study Filter' is showing now. Futures and Forex are a different story. def barNum = if IsNaN( close ) then Double.NaN else BarNumber(); Join 2,500+ subscribers inside the useThinkScript VIP Membership Club, VIP members get exclusive access to these proven and tested premium indicators: Buy the Dip, Advanced Market Moves 2.0, Take Profit, and Volatility Trading Range. This indicator will work on any instrument and on any time frame. 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. This study presents the 200 day moving average plot and a scan for within 10% of the MA(200). 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. VolAvg.SetDefaultColor(GetColor(8)); All four below produce the same result and also illustrate the ways to use references. You can define each separately and then use the two definitions in a single statement. def count = if crossingdown or crossingup then barnumber else 0; plot onceperchartup = if MostRecentOnly and crossingUP and count == highestall(count) then low else double.nan; plot onceperchartdown = if MostRecentOnly and crossingdown and count == highestall(count) then high else double.nan; onceperchartdown.setPaintingStrategy(paintingStrategy.BOOLEAN_ARROW_down); It may not display this or other websites correctly. https://usethinkscript.com/threads/repainting-trend-reversal-for-thinkorswim.183/, https://usethinkscript.com/threads/buy-the-dip-indicator-for-thinkorswim.3553/, https://usethinkscript.com/threads/answers-to-commonly-asked-questions.6006/. scan.SetLineWeight(5); `def yyyymmdd = GetYYYYMMDD(); `#Returns the date of the charts current bar. Item cut becomes available for pasting. AddCloud(CurrentPrice, Lower, Color.WHITE); input price = close;#hint price:This is the variable (11 choices) that will be plotted. This RSI is in conjunction with a MACD. By the way, you can identify a recursive variable definition when the variable itself, in this case 'count', also appears on right side of the equal sign/equation like, in this case, 'count[1]'. useThinkScript is the #1 community of stock market investors using indicators and other tools to power their trading strategies. level = 0; This result doesnt look like a date especially with the commas but it is. HMA > HMA[1] , THEN paint the plot with the Up color which is defined as color(1) OTHERWISE/ELSE paint the plot with the Down color which is defined as color (2). Below you see 5 conditions and plots showing when each condition is true or false ( 1 or 0). VolAlert.SetPaintingStrategy( PaintingStrategy.ARROW_UP); Vol.DefineColor("Down", Color.DOWNTICK); This document also proovides a reference for future coding activities. To be thorough and clear, you ought to code Harami().Bearish or Harami().Bullish instead depending on what you desire. It is useful to be aware of the techniques so that, when the time comes, you will know where to look to get the how-to-do specifics. Vol.DefineColor("Up", Color.UPTICK); For coding related to the day of week (Monday, Tuesday, etc.) An example is: def SlowK = StochasticSlow( 80, 20, 10, 10, high, low, close, "SMA" ).SlowK; Note that you cannot omit any intermediate values or modify their positions. The above reads 'scan for when the 15 bar exponential moving average crosses above the close'. where ???????? StochasticCrossover: The Stochastic Crossover for when the Stochastic Slow or Stochastic Fast crosses overbought (80%) or oversold (20%) level. One basic principle is that when you state for, example Doji(), when a doji is present Doji() returns 'true'. def plotPrice = CompoundValue(1, if timeTest then barnumber else plotPrice[1], barnumber); A 'setup' is a term/title applied to a group of charts and indicators that are used to implement a trading strategy. During trading hours this is also todays date. RefLine.SetLineWeight(2); Mode. 'Any text' is what appears inside the label box. A very common way of specifying the secondary aggregation is: def Agg = AggregationPeriod.FIFTEEN_MIN;# Use the desired constant to specify the time The wizard is auto accessible when coding new studies. At times coloring may also be used to do the same. plot MA50 = MovAvg50; low dispersion or deviation). Compare the two. These numbers are based on the columns "day" However, there are a number of places in TOS like Study Filters, Study Alerts, Custom Quotes, and Conditional orders that are allowed to use referenced studies. input percent = 20;#hint percent: Enter the percent increse/decrease boolean visible' is a true or false statement that defines when the label shows or doesnt show. In this example, if you want to identify what plot is the ORH, you uncheck 'Show Plot' and the click 'Apply'. Figures 3,4,5 brought to light some interesting aspects. Set it too high and you may unnecessarily be wasting server capacity. Also, this is a simple clear example of how the 'switch; function operates. ?-DAY and a ?? This will do it. Or it may be a arithmetic type like 'do nice * index' which multiplies folds internal variable, nice, by the index value. Multi variable linear regression model with 50 percent of the data used for training. The labels text can be defined using using 'concat' or '+' which is known as the string concatenation symbol. The multiple conditions may be used to define a conditional statements. Specify the threshold for the overbought-oversold value desired. Isnt that neat? Other examples of switch usage can be found at S-PRICE DIRECTION SCAN , S-PRICE DIRECTION SCAN, C-ATR TRAILING STOP and C- THE 'AdvanceDecline' STUDY. Note the importance of the index starting with 0. This is known as a runaway calculation. (1) and (2) are color index numbers.

"Advance/Decline Line (Breadth)" then "Advance/Decline Line (Breadth)" In essece, the SD is a measure of dispersion of the 100 datapoints. MACD and is included here for that reason. advnDecl = advances / declines; The distance of each of the 100 datapoints from the average is used to calculate (via a mildly complex formula) what is called the Standard Deviation (often abbreviated as SD). Defines whether to always show the label at the specified position, or on mouse hover only, or to hide it completely. When you have multiple conditions, at times it is difficult to know what conditions are firing and when. Def Example 8: The following code is used to scan for stocks having future earnings. This defines a condition, upon violation of which, the loop (not the fold itself) is terminated when calculating the fold function and TOS procedes to the next bar. They are also excellent for correlating the looks of a candle with its title. If not determine where your thinking went astray. It likely is 'day' but doesnt have to be.

Also the look-back and the look-forward lengths do not need to be the same. A nesting (putting ifs within ifs) example, in the recommended layout for easy reading, is: Note that the last 'else open' relates to the 'if close > open' and applies when the intermediate 'else-if close = open' is not true. VolAlert.SetLineWeight(2); def dayOpen = if firstBar then high else dayOpen[1]; plot x = dayOpen; Uses the data of the entire plot. If aggregation is set to 'Day' then 'agg-bars ago' is 2 days go, Ichimoku scan for crossing above the cloud, close crosses above Max(Ichimoku(). AddLabel(yes, "Arrow is at time = " + AsPrice(time) +" of each day" ,color.white); #hint:
MovingAverage Crossover - Once Per Chart\nThis study shows arrows when the price crosses the moving average. Comment 2: Thinly trader stocks may not have a bar at the time defined. Use of '' and "" Often the single and double quotes are used to identify precise coding, words or statements whose use is not intended to include the quote marks themselves. switch (choice) { Defines the time scale value corresponding to the begin point.
is a number. After the above global definition, GlobalColor("Purple") can be use wherever a color is needed. input length = 10;#hint Length:Length of the average I am afraid doing the entire calculation in thinkscript will have a heavy performance toll, especially if it is part of a scan over thousands of stocks. Re the recent release & Renaming studies. The Learning Centers 'charting/ThinkScript' ( Click here to see it ) is a must read for all newcomers to ThinkScript. Comment: You have a watchlist in either the left-hand panel or in 'Market Watch/Quotes'. It is recommended that you use a good PDF reader that has good navigation and search/find capabilities. The thinkscript documentation infers that there are more forms of the if-then-else, but the additional examples are merely the base form shown with nested if-then-else statements/expressions. We get it. This doesnt repaint to my knowledge. For example 4-days is a column agg choice but is not a choice of the chart Ratio_vol.SetPaintingStrategy(PaintingStrategy.HISTOGRAM); If you wanted to define a swing high as a bar high that is higher than the highs of the two bars just before it AND higher than the highs of the two bars just after it, the thinkscript code would look like this: Def swinghigh = if high > high[1] and high > high[2] and high > high[-1] and high > high[-2] then 1 else 0; Or if you are interested in the rise of the last 5 bars, you may use something like this: plot pivotHigh = if high == (highest(high, 5) and sum(high > high[-1], 5) == 5) then high else Double.NAN; The code for a swing low is similar. It is similar to the Market Forecast. else if price == high then "high" A Doji() is neither bearish nor bullish so Doji() is used alone. "DI+"; #MomentumCrossover: Scans for the Momentum crosses the zero line. The upper and lower channel lines, parallel to the centerline (the true linear regression)., indicate the furthest that the data has been from the middle line The '100' in the title means that it shows the upper and lower lines at 100% of the data difference from the centerline . declare lower; input length = 30;#hint length:the number of trading days-ago for the change Comment: The effectiveness of this system has not been verified. ?The answer lies in that this is an internal variable that fold uses. This tip is to use TOS 'ThinkLog' to store those rules for easy reference. On an intraday chart the IV will show N/A and the HV will be annual HV. {default NYSE, NASDAQ, AMEX}, does not have a case, then there must be a case default: In this example, each of the enums has a case so there is no case default:. Comment: A good example of a nested fold. else if price == open_interest then "Open_interest" Plot MFI_below = MoneyFlowIndexCrossover(crossingType == crossingType.below).signal; MovingAvgCrossover: Scans for crossovers of moving averages of different types and lengths. In the above HMA>HMA[1] is the condition that says IF the current HMA is greater than the previous value of the HMA, i.e. Using parameters is explained below. Pre market scans are not very efficient. declare upper; The conditions may qualify the do-actions results or they may define conditions that terminate any further loops at the current bar. advnDecl = AbsValue(advances - declines); If it is omitted, then the default value of 0 is used. for example check this trendline on daily one year chart for swbi , also look at one year daily chart on CIT , join Reg blue trendline for april 27th , june 3rd and present lows to form a trendline. aggregation. A simple example is: plot MyMACD = reference MACDHistogram; Occasionally a study and a function may have the same name e.g. RSIWilderCrossover: The RSI Wilder Crossover scans for an overbought-oversold indicator of specified levels. This section holds questions and support requests related to our premium ThinkorSwim indicators. Any moving average may be had by use of the flexible input selections. The coding of these may be copied and reused in your own studies but built-ins cannot be changed. crossup.hidetitle(); Plot Crossdown = !mostRecentOnly and crossingdown; Basically a swing high is the highest high looking a few bars back and a few bars forward. The MACDHistogramCrossover() has a choice of "Positive to Negative" or "Negative to Positive". There are two way to compose this text using 'concat' or '+' syntax(known as the string concatenation symbol). You take your basic code studythe one that plotted the arrows, and change the 'plot' statements to 'def' statements. Hence, this section will be as thorough as possible with many examples to illustrate their usage. can be any name you want but 'i' or 'index' is commonly used e.g. If you want to see a dot anytime the condition is true, then remove the '&& !cross[1]'. For your convenience, we added a label to the regression channel, which displays its principal parameters: the length (as expressed in both number of bars and time units such as days, hours, minutes, depending on the timeframe you are using), the price change correspondent to the difference between its start and end points (expressed in both absolute and percentage values), its slope, and the deviation value calculated in the specified mode (as an absolute value and also as a percentage of middle line start point value). Hence being familar with what is available herein, will enhance recall when needed. === below items not needed for a scan # In general, success in terms of and algorithm of actions, and not some magic scripts. not plotted). Note that the names like 'KPeriod', 'DPeriod', 'priceH', 'smoothingType' and others are as defined in the actual codes input list. Set agg = day. If you want to see the percentage for any bar under your cursor, then: (1) Check the 'show study' box in edit studies; OR (2) Change 'declare upper' to 'declare lower' and check all boxes in 'edit studies'. This code plots candles relative to the centerline of the linear regression channel (the linear regression line) and shows the movement relative to that. There are two ways of referencing constant inputs : smoothingType = "SMA" and smoothingType == smoothingType.SMA are equivalent.The first is the short syntax ("SMA"), while the second is the full syntax . else if exchange == exchange.AMEX then "AMEX" You can edit the study to change the symbol or the type of plot, i.e. You cannot operate on other variables or do anything within the fold. Here is what happens to the strategy if you overlay an Exponential Moving Average on the Linear Regression Curve, and trade using the following settings: I slightly modified this linear regression slop study to include an angle label. VolPct.hide(); can be over-ridden by the edit-studies check boxes I'm looking to further improve it by adding another angle label that changes the angel value as I hover my pointer over the slope line. Orders placed by other means will have additional transaction costs. There are times when a label interferes with the top of a plotted charts data. Script show. EMAs are great but so many times a fast line will cross a slow line but then turn right around and un-cross. Example 5: Uses sum to look for a divergence. The space you panned for will be recorded in 'Chart settings/time axis/expansion area'. Note that the LinearRegCh100 color cannot be changed because it is a built-in study and its code is non-editable. If you are inclined towards the use of concat, here is a guide on its use as well as an example of conditional coloring. Plot RSI_Cross_Below = RSIWilderCrossover(threshold = 30, crossingType = "Below").signal; The above reads 'scan for when the RSI Wilder crosses below 30'. Input Price = Close; Since it is in brackets, it is optional if there is a with . The AddChart function is unsupported in TOS, Hence there is no documentation to support its use and color formatting. Set this property to "On" to extend the regression channel all the way to the right. You can also use color changes to identify various plots. Our forum can be intimidating, if not overwhelming. See REFERENCES for a reader source. So when/why would you include this. But the problem with many shorter timeframe traders is over trading and trying to trade against the trend at times for scalps. . The volume histogram; 2. We'll run it in the context of three different indicators. You must, Super 6x: RSI, MACD, Stoch, Loxxer, CCI, & Velocity [Loxx] for ThinkOrSwim, How To Enable Thermo Mode For ThinkOrSwim, NQ 1 minute Scalping Indicator For ThinkOrSwim, Scan request: current price is down 1.5 times of ATR, Indicator for 3rd consecutive swing low or high needed. Notice that each statement is enclosed within a block (the parts enclosed in the { } ) and must end with a semi-colon. Remember that the fold calculation is executed at every bar as ThinkScript processes from bar 1 to the last bar. In summary, all date/time functions beginning with 'Get..', except for GetDayOfWeek and GetDayOfMonth, have no parameters. input GapPct = 0.5;#Hint GapPct: The gap-up percent The Linear Regression Slope study displays expected price change based on linear regression analysis using the least squares method. else if price == open then "open" Some are especially useful at selecting text by letter, word, line, paragraph, window, etc. The defaults are accelerationFactor = 0.02, accelerationLimit = 0.2. plot RefLine = Ref_val; Alternate 3: Plot a dot below the bar that crosses and only that bar. You can use either the ThinkScript functions or calculate the variables for Linear Regression and Standard Deviation which ever you prefer. CloseLine.SetDefaultColor( Color.gray); #Hint: Plots the %-change-of-the-first-bar-value. This is useful when assessing price changes and comparisons. These can be located within the channel and outside it. Those are the default parameters and cannot be changed because they are in a pre-defined study which is not editable. TD Ameritrade does not make recommendations or determine the suitability of any security, strategy or course of action for you through your use of our trading tools. The names assigned and are persistent variables. The SUM function has some versatile usage as illustrated in the coding examples below. If your definition of the label text involves long and multiple 'ifthenelse' statements, to insure that they all print, enclose each 'ifthen else' statement in parentheses e.g. high dispersion or deviation). scan.SetpaintingStrategy(paintingStrategy.BOOLEAN_ARROW_up); Using 'NumberFormat.DOLLAR' produces the same look as using 'AsDollars'. RegularTradingStart(int yyyyMmDd); Returns the start of the regular trading hours for the current symbol on the trading day specified in the YYYYDDMM format. Building Applications. def LunchTime = TwelveOclock > 0 && TwelveOclock[1] 0; AddVerticalLine(MarketOpen or LunchTime,if MarketOpen then "TIME TO TRADE!" You may want to see how its price varies with the oil futures. Below is a useful list of those available in Win 7, the TS editor and most editing programs. else "") + " for the " If the close is not greater than the open and the close does not equal the open, then plot the open. def a = barnumber - data; Plot Arrow = If TimeTest then close else double.nan; https://usethinkscript.com/threads/tradingviews-linear-regression-indicator-for-thinkorswim.3721/Linear regression channels are quite useful technical analys. GetYYYYMMDD() is the most frequently used. While doing this you can observe which plot is ORH because it disappears. Lower.HideTitle(); plot CurrentPrice = ((price / Lowest_Low) - 1) * 100; AddCloud(HH_LL_Pct, CurrentPrice, Color.GREEN); Even a small anti trend move lowers the efficiency reading. Once again, you must preserve the parameters position rule. Vol.SetPaintingStrategy(PaintingStrategy.HISTOGRAM); So I converted the PDF to Asciidoctor html format. Use of a switch inside a switch is possible but is very complex. "Span B"), Ichimoku scan for crossing below the cloud, close crosses below Min(Ichimoku(). Defines an action to be performed, for each loop, when calculating the fold function. `plot Test = fold i = 1 to 5 with x = 10 do x + i; `. When the counter gets to 5, fold stops and there is no results related to loop 5. Naturally any valid condition may be substituted for the one shown. case "Advance/Decline Line (Daily)": scan = chg >= percent; The format thenbecomes 'if..then.. else if..then..else if..thenelse'. else if price == hlc3 then "hlc3" This is known as a bullish regression channel. The heart of the fold function is the 'do expression' which is crucial for success but is not naturally intuitive. Plot scan = reference MypriceTrend(Price = hlc3, length = 7, choice = "increased"); Note that 'hlc3' may be any parameter such as open, hugh, low, hl2, volume, etc. "Advance/Decline Spread (Issues)" then "Advance/Decline Spread (Issues)" If you are new, or just looking for guidance, here are some helpful links to get you started. JavaScript is disabled. level = 0; input VolAvgLength = 50;#hint VolAvgLength:Insert the base agg-bars volume length Long series of 'if conditions' also can create the 'too complex error'. Forex accounts are not available to residents of Ohio or Arizona. A chart may also have one or more secondary aggregations. No other changes, except that I added Bitcoin to the test group. To make an 'Info Bubble' for a study and strategy: Above the code lines, place #hint: ???????? 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. TOS has also assigned names to 23 colors per the following: Reference: [See all color constants](https://www.thinkorswim.com/tos/thinkScriptHelp.jsp?laf=dark#constants). Fast Stochastics; 2.

When GetYYYYMMDD() is compared to an inputted date the commas are omitted in the input date. What is a swing high / low? This simple fold sums the 'index' values. Many items herein originated on the those chatroom postings. Also configure the chart to synchronize the cursor across all grid charts via Chart settings/general tab/Synchronize crosshair position. The Revenue Optimization Analyst will track revenue over time and determine how . Also the decimal places can be gotten by using the Round() function as shown above in the 'AsDollars' example. This indicator will automatically curve-fit a polynomial regression channel. to +100, or whatever you want. Setups frequently have rules re what needs to exist to implement its buy/sell strategy. TOS has defined ten colors corresponding to index numbers on two different background colors as below: The colors are used via the function 'GetColor(index number);' Example: GetColor(1) as used in the HullMovingAvg previous topic.
