There is a complete tutorial named Aggregation Tutorial,PDF available at http://mytrade.com/StanL. 9 loops are run i.e. the liberty to include TOS-platform-features that are not only script snippets but d.setPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP); So within that context, certain functions make no sense, like barNumber(), HighestAll() to name a few, also rec variables. "); case AMEX: 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. 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. Since no parameters are specified, the default parameters specified in the actual code are automatically used. 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. 0 to 100%, -1 to +1, -100 Labels are boxes of info placed at the top-left of a study. 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. each parameter/input has a fixed location in the list.

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). Some examples are below. === below items not needed for a scan # Vol.DefineColor("Down", Color.DOWNTICK); There are no limits to the number of conditional statements but they follow the format if..then.else if..then..else if..then..else. then.

That is literally just a copy and paste job on the linear regression channel that comes free in TOS anyway, at multiples of 0.375. If you want to compare two (or more) indicators that have values much different (1) and (2) are color index numbers. The Linear Regression Slope study displays expected price change based on linear regression analysis using the least squares method. Clusters are powerful points for buy/sell decisions. calendar (not trading) days from an inputted date\n This works only on a lower plot and not for HA and EquiVolume charts., Input DaysToPlot = 20;#hint DaysToPlot: the number of calendar days to plot. This distance is equal to the value defined by the calculation mode, multiplied by the coefficient. This is a reminder of an especially valuable resource for new learners of ThinkScript as well as a refresher for you 'pros' out there. Using the examples guides you re what parameters are applicable and how you may change them to suit your desires.

Compare the two. This includes converting ThinkScript variable-values into text. ' To facilitate implementing a multiple-time-frame approach consider establishing a named grid with each grid component having the charts and indicators at the time frames that you are interested in. Full Stochastics. 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. The defaults are accelerationFactor = 0.02, accelerationLimit = 0.2. As converting from PDF is a lot of work, This is a work in Uses the data of the entire plot. When is used in the do statement, the last value of is used and not the current value. script. def term = x*price2[1]; # = factor * previous high You can tweak it in the input or the code how you see fit for you. #.

This is a limitation of ThinkScript that we must live with as best we can. Set this property to "On" to extend the regression channel all the way to the right. else if price == ohlc4 then "The price-variable selected is ohlc4 = " + Round(ohlc4,2) This study presents the 200 day moving average plot and a scan for within 10% of the MA(200). Portable Document Format = the type of file format of this document. NO BAR THEN THE DATE/TIME RETURNED VALUES ARE NOT RELIABLE. 5 run average: 4.752 s. Relative performance: 0.7% faster.

In order to add the regression channel to chart, choose it from the Active Tool menu. else if price == VWAP then "The price-variable selected is VWAP = " + Round(VWAP,0) level = 0.5; I find that frequently changing the timeframe of charts is much easier to read when I have vertical lines as market start and end times. The defaults are length = 14, threshold = 30. The coding of these may be copied and reused in your own studies but built-ins cannot be changed. During trading hours this is also todays date. You may have a label take on the same color as a plot. #Hint: Plot for ? The statement "if AggPeriod == AggregationPeriod.DAY then else;" reads: if the variable AggPeriod equals (is the same as) AggregationPeriod.DAY then do something else (otherwise) if its not, then do some other thing. input Ref_val = 25;#hint Ref_val:The reference percent. ThinkScripts linear regression function is titled 'Inertia'. Examples will help explain: Using the '' symbol . This code was developed to show the minutes-ago that the stock started to turn up. Each RGB component ranges in value from 0 (meaning none or 0%) to 255 (meaning the max 100% value). since/when close is not a number then 'isnan(close)' reads as true. In realtime coding, the +1 is replace by all kinds of conditions and resulting actions. A powerful signal is present when both speeds are simultaneously below OS or above OB. Orders placed by other means will have additional transaction costs. RSIWilderCrossover: The RSI Wilder Crossover scans for an overbought-oversold indicator of specified levels. For an example, let us create an exponential moving average on our BTC data: that are non-receptive to comparison, you can normalize each of the two (or more) case NASDAQ: else if price == low then "The price-variable selected is low = " + Round(low,2) Note that LinearRegCurve, LinearRegTrendline, and LinearRegressionSlope all have the same eleven price input choices.

This pattern has often been referred to as a 'bull flag' or 'bull pennant'. Note: this action will not recalculate the whole channel, but just extend the existing lines. This is the bubble in e right margin and not on the chart itself. Go to 'Drawings' and select the 'Pan' tool . else if price == IMP_VOLATILITY then "imp_volatility is not a valid choice" So the MACD will look like 'MACD_ME'. The SUM function has some versatile usage as illustrated in the coding examples below. This reads as 'scan for stocks with a DMI_Oscillator value greater than 10 and rising for the last 5 agg-bars. #VolPct.SetDefaultColor(Color.PINK); Hey everyone. However, at times, clicking the right location can take many tries.
