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. This page demonstrates the most useful techniques to debug Pine code. It might be possible to optimize algorithm to overcome this error. security every call to this function will count as a security call. For example: As strings manipulated in Pine scripts often do not change bar to bar, the method most frequently used to visualize them is to draw a label on the datasets last bar. Anyone who has coded in pine-script will no doubt agree that debugging can be a pain in the backside. But neither with the iff() function or conditional operator. I hope you find the articles helpful with your programming tasks. This script showcases a few different uses of plot() maximum length of series used in a script.

Note how the pivot on the bar indicated by the arrow has just been detected in the realtime bar, three bars later, The 'main scope' are all statements that are placed at the script's main indentation level. This gives us a general idea of the values being used in each loop iteration: We can also extract multiple values from loop iterations by building a single string which we will display using a label after the loop executes: When loops with numerous iterations make displaying all their values impractical, you can sample a subset of the iterations. and how no plot is drawn. Values plotted by Pine scripts can be displayed in four distinct places: Note the following in the preceding screenshot: The script in the preceding screenshot used the simplest way to inspect numerical values: a plot() call, we will plot the variable using plotchar() like this: Pine Script labels must be used to display strings.
