This behavior is described in more detail in the section about drawings. Values plotted by Pine scripts can be displayed in four distinct places: Next to the script's name (controlled by the Indicator Values checkbox in the Chart settings/Status Line tab). While this isnt documented, functions that plot and colour cannot be used in a local scope. The 'main scope' are all statements that are placed at the script's main indentation level. How to put plot statement inside if statement.

This code uses the % (modulo) operator to include values from every second loop iteration: The two techniques we use most frequently to debug our Pine Script code are: to plot variables of type float, int or bool in the indicators values and the Data Window, and the one-line version of our print() function to debug strings: As we use AutoHotkey for Windows to speed repetitive tasks, we include these lines in our AutoHotkey script (this is not Pine Script code): The second line will type a debugging plotchar() call including an expression or variable name previously copied to the clipboard when we use ctrl + shift + f. Draw vertical line at the first bar of the month in tradingview's pine script. This line of code is telling Pine Script "Create me a variable named 'highestHigh'. In this script we have written the hlca() function to calculate a weighed average: We need to inspect the value of hlca in the functions local scope as the function calculates, bar to bar. with different scales in the same visual space, even when their values, contrary to About an argument in Famine, Affluence and Morality. Calls to plot() can, however, tradingview pine script error "cannot use 'plot' in a local scope" See, Our pivots are detected three bars after they occur because we use the argument, The last plot is plotting a continuous value, but it is setting the plots color to, The blue dot indicates when a new high pivot is detected and no plot is drawn between the preceding bar and that one. Try using max_bars_back in the study or strategy function. alertcondition() calls, e.g. The limit TRADINGVIEW--PINE SCRIPT : PLOT SHAPE AND TEXT - YouTube That leaves us with no option to use this risk function conditionally.

To learn more, see our tips on writing great answers. What I'm trying to do: This has the advantage of requiring less runtime resources, but entails that you identify When that argument has a colour value, the bar gets coloured. Why do small African island nations perform better than African continental nations, considering democracy and human development? In the above example, study () and the if statement are examples of that. The third call plots a 3-pixel wide step line following the low point of bodies. Inside the code block of that if statement two things happen. (See next entry.). It is versatile and can plot different styles of lines, histograms, areas, columns (like volume columns), fills, circles or crosses. Displayed below are two scripts of the same indicator output..the first is the attempt to modify the script to MTF using the security () function, and the second is the script without MTF that works perfectly using global scope resolution="" defined in the study header. The plot will only appear on the next bar, making the plot visible, The 100 levels are plotted using a conditional value that only plots every second bar. values in the same space by adding the following line to our script: The chart is on the BTCUSD symbol, whose close but you can also use plot() like this: Pine Script has an hline() If I try to run it, I get: cannot use 'plot' in a local scope. If we wanted to show only one level, we could use the same technique while isolating a specific loop iteration as we did in the preceding example. To choose between those we can use the conditional operator or iff() function. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. In turn, because the initialization of result is the return value of the our functions local block, This script showcases a few different uses of plot() Can archive.org's Wayback Machine ignore some query terms? // Loop through an array of lines, extending those that price has not crossed and deleting those crossed. :) or iff() function. because it does not use a loop and uses the any ideas of how to plot it? be known on the current bar, e.g., to find how many past highs are higher than the. Instead we have to use the functions series argument. In The objective (once it is working) is to eventually have several . To decide between those two we can use the conditional operator (? As in functions, such variables are also local to the loops scope. But then you first have to make a variable that holds the plot condition: This function makes a strategy trade long or short only (TradingView, n.d.). What we can do is set the functions series argument with a condition. :) or the iff() function. That requires first making a variable with the plot condition, though: The plotshape() function plots visual shapes (like arrows, crosses, or diamonds) on the chart (TradingView, n.d.). Those include the code blocks of if statements, but also the body of custom functions. Pine Script Language Reference Manual. Shift it higher by 150, so its -50 min value becomes 100. can be a literal, a variable, an expression or a function call. cannot be used in conditional structures such as if, Without the ability to print to the terminal, we are forced to plot anything and everything we wish to inspect. We use the input.time() function But the conditional operator or iff() function neither help; this functions arguments cannot be set conditionally.

The crosses are colored lime when the bar is up and purple when it is down. Tradingview--pine Script: Error = Can Not Use Plot in The Local Scope Anyone who has coded in pine-script will no doubt agree that debugging can be a pain in the backside. (bar zero, i.e., bar_index == 0 or barstate.isfirst == true), as will be the case when the information needed to determine a color depends on the chart the script is running on. So you can try to switch to version 2 by Our example script plotted the value of the bar_index built-in variable, When it evaluates to, The value assigned to the variable is the return value of the , These functions dont work in if statements: The alertcondition() function creates an alert condition programmatically (TradingView, n.d.). Here we draw a line corresponding to the value of tr used in each loop iteration. We thus need another mechanism to pull that variables value from inside the functions local scope, while still being able to use the functions result. This script shows a few ways to do it: This script shows how you can restrict plotting to bars after a user-defined date. To learn more, see our tips on writing great answers.

This shows a CCI Here, we explore three different techniques to inspect variable values originating from for loops, starting from this code example, which calculates the balance of bars in the lookback period which have a higher/lower true range value than the current bar: If we want to inspect the value of a variable at a single point in the loop, we can save it and plot it once the loop is exited. The scale of the scripts pane is automatically sized to accommodate the smallest and largest values plotted by all, The RSI line in black is flat because it varies between zero and 100, but the indicators pane is scaled to show the maximum value of, Lastly, note how a boolean variable with a, We use two different shades of green to color the background: the brighter one indicates the first bar where our compound condition becomes. Copying the variableName variable name or the close > open conditional expression to the clipboard and hitting ctrl + shift + f will, respectively, yield: The third line triggers on ctrl + shift + p.
