With title we name the indicator. When we already have other plots going on and adding debugging plots of variables whose values fall outside the scripts plotting boundaries would make the plots unreadable, another technique must be used to inspect values if we want to preserve the scale of the other plots. If the box is checked, the plot the line. and how no plot is drawn. // Only evaluate the function on the first bar. It is impossible, for example, to correctly plot an But luckily, as an alternative, we can use this function conditionally. This is how it should be done. We can use Pines ability to have functions return a tuple to gain access to the variable: Contrary to global scope variables, array elements of globally defined arrays can be modified from within functions. This line, for example, plots a start whenever the condition (two bars in a row that close higher) is true: With an extra step we can also use plotchar() with an if/else statement.

The We also use a label to display, for each line, the loops index and the lines value. While it is not always strictly necessary to assign individual conditions to a variable because they can be used directly in boolean expressions, series has been shifted to the right (its value is positive). It must be indented by four spaces or a tab. after compilation: Usually this error occurs in version 1 pine scripts, and means that code wrapped up into the main function and the limit of 1000 variables This, for instance, plots a diamond only when the bars close is above the 10-bar exponential moving average: Its not impossible to use plotshape() with an if statement. flow of execution does not allow Pine to inspect the use of series in explaining errors of this kind.

The state of multiple individual conditions can be displayed using a technique like this one, where four individual conditions are used to build our bull compound condition: Variables in function are local to the function, so not available for plotting from the scripts global scope. We cannot access the _hlca variable used inside the function from the scripts global scope. This is the code I have: notPlot = -2000 var ch382= input (true, ".382") if ch382 plot ( ch382? // Set the array's only element to the current value of `_instantVal`. This page demonstrates the most useful techniques to debug Pine Script code. But the conditional operator or iff() function neither help; this functions arguments cannot be set conditionally. Suppose we want to continue inspecting the value of bar_index, but this time in a script where we are also plotting RSI: Running the script on a dataset containing a large number of bars yields the following display: In order to preserve our plot of RSI while still being able to inspect the value or bar_index, If RSI values were plotted as an overlay on the chart, Performing calculations on past bars that cannot be accomplished using Pine Scripts built-in functions, (TradingView Pine Script).
